Unity Vector Graphics Preview Package

I also have a problem with the SVG coordinates (may be I'm using it wrong?).

I created tree layers of objects I like to import as seperate objects. After this I want to create 3D-objects from the tessellated shapes out of the SVG planes.


As mentioned on page 3 using SVGRuntimeLoad.cs I manipulate the vector scene to create three objects out of the source SVG. I remove the unwanted nodes in each copy. The problem is that the SVG coordinates are not stored on each part resulting in a wrong positioning. Is this the result of the SVG coordinates bug mentioned earlier on page 4?

Code (CSharp):

1.  
2.         var sceneInfo = SVGParser.ImportSVG(new StringReader(svgText));
3.         int NrOfLayers = sceneInfo.Scene.Root.Children.Count;
4.         m_Sprites = new Sprite[NrOfLayers];
5.         SVGParser.SceneInfo[] m_SIArray = new SVGParser.SceneInfo[NrOfLayers];
6.         List<VectorUtils.Geometry>[] m_Geoms = new List<VectorUtils.Geometry>[NrOfLayers];
7.         for (int i = 0; i < NrOfLayers; i++)
8.         {
9.             m_SIArray[i] = SVGParser.ImportSVG(new StringReader(svgText));
10.             int removed = 0;
11.             for (int c = 0; c < NrOfLayers; c++)
12.             {
13.                 if (c!=i)
14.                 {
15.                     m_SIArray[i].Scene.Root.Children.Remove(m_SIArray[i].Scene.Root.Children[c- removed]);
16.                     removed++;
17.                 }
18.             }
19.  
20.             m_Geoms[i] = VectorUtils.TessellateScene(m_SIArray[i].Scene, tessOptions);
21.             m_Sprites[i] = VectorUtils.BuildSprite(m_Geoms[i], 10.0f, VectorUtils.Alignment.SVGOrigin, Vector2.zero, 128, true);
22.             GameObject go = new GameObject();
23.             SpriteRenderer s = go.AddComponent<SpriteRenderer>();
24.             go.transform.parent = transform;
25.             s.sprite = m_Sprites[i];
26.         }

m_Sprites = VectorUtils.BuildSprite(m_Geoms, 10.0f, VectorUtils.Alignment.Custom, Vector2.zero, 128, true);

m_Sprites = VectorUtils.BuildSprite(m_Geoms, 10.0f, VectorUtils.Alignment.SVGOrigin, Vector2.zero, 128, true);

How can I get all layers aligned to the original SVG origin of the source SVG?
Thank you and kind regards!

 

Hi, it's me again.
After some work and research, I was able to create an editor script to generate UV coordinates for sprites in the asset folder using the SpriteDataAccessExtensions.SetVertexAttribute(...) method. However, it turns out that this change isn't permanent. As soon as I either relaunch the editor or modify the import setting of an SVG file, the UV coordinates are reset to 0. Unless I missed something, it appears there's no way to change the UV coordinate permanently.
Here's the code I use to set the UV :

Code (CSharp):

1. public class GenerateUV
2. {
3.     [MenuItem("Assets/Fill UV")]
4.     private static void FillUV()
5.     {
6.         foreach(Object obj in Selection.objects.Where(x => x is Sprite))
7.         {
8.             Sprite sprite = obj as Sprite;
9.  
10.             NativeSlice<Vector2> UV =
11.                 SpriteDataAccessExtensions.GetVertexAttribute<Vector2>(sprite, UnityEngine.Experimental.Rendering.VertexAttribute.TexCoord0);
12.  
13.             NativeSlice<Vector3> Position =
14.                 SpriteDataAccessExtensions.GetVertexAttribute<Vector3>(sprite, UnityEngine.Experimental.Rendering.VertexAttribute.Position);
15.  
16.             Vector2 min = new Vector2(Position.Min(x => x.x), Position.Min(y => y.y));
17.             Vector2 max = new Vector2(Position.Max(x => x.x), Position.Max(y => y.y));
18.  
19.             NativeArray<Vector2> newUV = new NativeArray<Vector2>(UV.Length, Allocator.Persistent);
20.  
21.             Vector2[] UVarray = new Vector2[UV.Length];
22.  
23.             for (int i = 0; i < UVarray.Length; ++i)
24.                 UVarray[i] = new Vector2((Position[i].x - min.x) / (max.x - min.x), (Position[i].y - min.y) / (max.y - min.y));
25.  
26.             newUV.CopyFrom(UVarray);
27.  
28.             SpriteDataAccessExtensions.SetVertexAttribute(sprite, UnityEngine.Experimental.Rendering.VertexAttribute.TexCoord0, newUV);
29.  
30.             newUV.Dispose();
31.         }
32.     }
33.  
34.     [MenuItem("Assets/Fill UV", true)]
35.     private static bool TypeValidation() => Selection.objects.Any(x => x is Sprite);
36. }

 

@mcoted3d: Thank you for the hint. I tried all possible ways of calculating the correct pivot but failed in getting correct results. The best way - which worked so far - is using topLeft positioning and changing the position of the created child gameobjects:



m_Sprites = VectorUtils.BuildSprite(m_Geoms, 1000.0f, VectorUtils.Alignment.TopLeft, position, 128, true);



and later reposition of the created gameobjects with the resulting Bounds-positions
go.transform.position = new Vector3((localBounds.x)/1000f, (fullBounds.y - localBounds.y) /1000f , 0);

There is still a problem with the positions, so that this is not perfectly aligned:


In the original SVG the positions fit perfectly:


I hope on the updates you've mentioned. Is there a release date for the next update of the toolset?

For testing purposes I've attached the source code I used.

Thank you and kind regards!

 

I've sent you the example file via PM as it contains a production asset I don't want to put into the public.

 

There seems to be an issue with the pivot. When using the SVG Importer from the asset store and setting the pivot to an arbitrary point on the SVGs original canvas size, the animation plays back smoothly.

However when using the vector graphics package by Unity Technologies, we set the pivot to "SVG Origin" but still have some frames "jumping" or "moving" out of their supposed position. Is this a known issue?

 

Works like a treat! only wishlist is to somehow compare the id that is exported out from Ai incase someone decides to move the layers in Ai.

And also if there's an easy way to reference the svg string of a svg file in the Project assets. Wasn't sure if this was already been asked previously. Such as a svg file to be assigned to a custom ScriptableObject public variable.

 

I was wondering, is it possible to use SVG in a ParticleSystem?

Edit: Found a way to do this. You can generate a Texture2D from the SVG sprite and use it in a ParticleSystem by using his method :

Code (CSharp):

1. public static Texture2D RenderSpriteToTexture2D(
2.     Sprite sprite,          // The sprite to draw
3.     int width, int height,  // The texture dimensions
4.     Material mat,           // The material to use (should be Unlit_Vector or Unlit_VectorGradient)
5.     int antiAliasing = 1);  // The number of samples per pixel

 

Hi, I have an issue when import SVG runtime
I use SVGRuntimeLoad.cs in https://github.com/Unity-Technologies/vector-graphics-samples.
Mesh generate runtime different with svg import direct. See image below.


How can i get the result same with direct import?
Thanks,
Deviros.

 

Are there performance advantages to using this geometry based drawing over using bitmaps (and eating up fillrate) on modern mobile devices?

 

Still experiencing this in preview.15. Is a fix under way?

 

This is great. Any idea on when anima2d will support this and when it will be supported in UI elements?

Thanks!

 

It work.
Thanks

 

Thanks, I'm still not using it in production. So I can wait for the update ;-)

 

@mcoted3d for all that is good in the world, please add render-to-texture with alpha!

Please!

I will personally donate funds. And pizzas. And beer. And donuts. Whatever it takes.

 

THANK YOU.

WONDERFULL!!

No need compression, no need mipmaps. Both of these can be done manually, thanks to having the vector format and render to texture, with alpha!

Let me know if/when/where pizzas/beer etc needed to make this happen faster/better.

 

Are these new vector sprites supposed to work with UnityEngine.UI.Image?
If not, is support planned in the near future?

The SpriteRenderer seems to have different sorting rules, and always draws behind our UI, and I haven't found a found a way to make it sort normally.

Thanks

 

I though Anima2d was an in-house asset: the developer is set to "unity technologies". If this is not the case, this is very misleading!

https://assetstore.unity.com/packages/essentials/unity-anima2d-79840

 

I believe, Anima2D is no longer in development except for simple support/fixes.

Unity has a replacement for Anima2D in development: https://forum.unity.com/threads/2d-animation-preview-packages.521778/

I would love to see the Vector stuff work with this new 2D animation system.

 

Could you please comment on why this is?

I considered trying to rig something up myself, which would have involved inheriting UnityEngine.UI.Image, and overriding OnPopulateMesh to use the vertices from an SVG asset instead or the standard quad or 9 patch. Does this sound viable, or is there something I'm missing?

Thanks

 

I've attempted to use a AssetPostprocessor method to fill TexCoord2 with UV mapping using this method.

SpriteDataAccessExtensions.SetVertexAttribute(sprite, UnityEngine.Experimental.Rendering.VertexAttribute.TexCoord2, newUV);

However, while I'm able to confirm using GetVertexAttribute(...) that TexCoord2 is indeed filled, it appears my shader's TEXCOORD2 (as well as any other TEXCOORD) parameter is using data from TexCoord0 instead. I'm not sure if the root of this problem lies outside the scope of this package, so I'm sorry if that's the case, but right now, Filling TexCoord2 isn't cutting it.

This is the AssetPostprocessor class to fill the UV.

Code (CSharp):

1. public class SVGPostprocess : AssetPostprocessor
2. {
3.     void OnPreprocessAsset()
4.     {
5.         if (!(assetImporter is SVGImporter)) return;
6.         SVGImporter importer = assetImporter as SVGImporter;
7.  
8.         if (!(importer.targetObject is Sprite)) return;
9.         Sprite sprite = importer.targetObject as Sprite;
10.  
11.         NativeSlice<Vector2> UV =
12.             SpriteDataAccessExtensions.GetVertexAttribute<Vector2>(sprite, UnityEngine.Experimental.Rendering.VertexAttribute.TexCoord2);
13.  
14.         if (!UV.All(x => x == Vector2.zero)) return;
15.  
16.         NativeSlice<Vector3> Position =
17.             SpriteDataAccessExtensions.GetVertexAttribute<Vector3>(sprite, UnityEngine.Experimental.Rendering.VertexAttribute.Position);
18.  
19.         Vector2 min = new Vector2(Position.Min(x => x.x), Position.Min(y => y.y));
20.         Vector2 max = new Vector2(Position.Max(x => x.x), Position.Max(y => y.y));
21.  
22.         NativeArray<Vector2> newUV = new NativeArray<Vector2>(UV.Length, Allocator.Persistent);
23.  
24.         Vector2[] UVarray = new Vector2[UV.Length];
25.  
26.         for (int i = 0; i < UVarray.Length; ++i)
27.             UVarray[i] = new Vector2((Position[i].x - min.x) / (max.x - min.x), (Position[i].y - min.y) / (max.y - min.y));
28.  
29.         newUV.CopyFrom(UVarray);
30.  
31.         SpriteDataAccessExtensions.SetVertexAttribute(sprite, UnityEngine.Experimental.Rendering.VertexAttribute.TexCoord2, newUV);
32.  
33.         newUV.Dispose();
34.     }
35. }

This is how I attempt to pass it to the shader.

Code (CSharp):

1.             struct appdata
2.             {
3.                 float4 vertex : POSITION;
4.                 fixed4 color : COLOR;
5.                 float2 uv : TEXCOORD2;
6.             };
7.  
8.             struct v2f
9.             {
10.                 float4 vertex : SV_POSITION;
11.                 fixed4 color : COLOR;
12.                 float2 uv : TEXCOORD2;
13.             };

It seems like the shader is ignoring TEXCOORD2 altogether and get whatever is in TexCoord0 instead.

 

Fantastic! Native SVG support coming to Unity.

I've used RageTools svg in a previous game and spent a year with SVG Importer asset making this game. Everything apart from the 3d doors and food is a vector (mesh).
http://www.cowlyowl.com/games/sizzle-stew/

I'm trying to entirely using SVGs and if I can do that without relying on a third party plugin, great! I've downloaded 2018.2.6 and the package to give it a try on my game assets.

I like that the original SVG is unaffected, still there for you to update without making a new asset.

Are the shaders for SVG sprites transparent or opaque?

I used entirely opaque in my game, no sort layer order, used z position for depth for better performance.

How do you get around z fighting on a sprite that has many layers that overlap? In SVG Importer (asset) you had to have some z distance between layers.

As mentioned above, the ability to colour tint without effecting draw calls or performance would be great (something I can do in SVG Importer).

Someone mentioned particles, it depends on what your particles look like. I ended up making all my particles as svg shapes (smoke etc), using SVG Importer to save out the raw Mesh and using that in the Particle System. The ability to export a mesh from this package would also be very welcome.

Keep up the good work.

 

Do you have any plans to write an opaque shader, or provide details how this one could be changed to be opaque?

If you aren't using any alpha, then it is a performance hit. It is much better for mobile to use complete opaque objects and avoid overdraw.

Otherwise using the built in SVG is going to be a big no go for may people.

Thanks

 

Still no plans/schedule for Canvas UI?

 

I'm trying to do something along the lines of this post (top of page 5) – which is itself based off of the samples – but in the editor instead of at runtime. The idea is that we'd like to make a prefab which is an imported SVG broken down into its component parts, so we can manipulate it in the editor (make animations, &c).

However, it keeps tripping up at the VectorUtils.BuildSprite() line, with:

Not allowed to override geometry on sprite ''

Looking elsewhere, it seems like this might trace back to BuildSprite() using Sprite.overrideGeometry, which apparently cannot be used in the editor.

Is there a way around this, or some other way I could interrupt/complement the SVG importer to create the different layers of the SVG as assets on disk?

 

Thanks a bunch for that, you pointed me in exactly the right direction. Using
OnPostprocessAllAssets(), I call this function, which is a slightly modified version of (rab's version of) the sample code:

Code (CSharp):

1. static void SvgLayerImporter(string assetPath) {
2.     var originalSvgPathFull = Application.dataPath.Substring(0, Application.dataPath.LastIndexOf("/") + 1) + assetPath;
3.  
4.     var sceneInfo = SVGParser.ImportSVG(File.OpenText(originalSvgPathFull));
5.     if(null == sceneInfo.Scene) {
6.         Debug.LogError("Could not parse SVG at " + originalSvgPathFull + "!");
7.  
8.     } else {
9.         Debug.Log("Custom import: " + originalSvgPathFull);
10.  
11.         // this could probably stand to be specified elsewhere
12.         var tessOptions = new VectorUtils.TessellationOptions() {
13.             StepDistance = 100.0f,
14.             MaxCordDeviation = 0.5f,
15.             MaxTanAngleDeviation = 0.1f,
16.             SamplingStepSize = 0.01f
17.         };
18.  
19.         // duplicate the original SVG prefab and create a GameObject that will serve as a pretend "instance" of that prefab
20.         var newPrefabLocation = assetPath.Replace(".svg", " (Split).prefab");
21.         var newPrefab = PrefabUtility.CreateEmptyPrefab(newPrefabLocation);
22.         var instPrefab = new GameObject();
23.  
24.         // go through each layer of the SVG, and in each layer, remove SVG info nodes that are *not* in that layer
25.         int numOriginalLayers = sceneInfo.Scene.Root.Children.Count;
26.         for (int i = 0; i < numOriginalLayers; ++i) {
27.             var newSceneInfo = SVGParser.ImportSVG(File.OpenText(originalSvgPathFull));
28.             int removed = 0;
29.             var layerName = "";
30.             for (int c = 0; c < numOriginalLayers; ++c) {
31.                 if (c == i) {
32.                     layerName = "Layer " + c;
33.  
34.                 } else {
35.                     newSceneInfo.Scene.Root.Children.Remove(newSceneInfo.Scene.Root.Children[c - removed]);
36.                     ++removed;
37.                 }
38.             }
39.  
40.             // instantiate the current layer as a new sprite in the scene, and attach it to our new prefab which will soon be saved to disk
41.             var geom = VectorUtils.TessellateScene(newSceneInfo.Scene, tessOptions);
42.             var newSprite = VectorUtils.BuildSprite(geom, 10.0f, VectorUtils.Alignment.SVGOrigin, Vector2.zero, 128, true);
43.             newSprite.name = layerName;
44.            
45.             // each SVG layer will have a corresponding GameObject that's part of the new prefab
46.             GameObject go = new GameObject(layerName);
47.             SpriteRenderer s = go.AddComponent<SpriteRenderer>();
48.             s.sprite = newSprite;
49.             go.transform.SetParent(instPrefab.transform);
50.  
51.             // bundle the new sprite (for this layer) in with the new SVG prefab
52.             AssetDatabase.AddObjectToAsset(newSprite, newPrefab);
53.         }
54.  
55.         // now apply the changes from the instantiated prefab to the saved prefab on disk, and destroy the instance
56.         PrefabUtility.ReplacePrefab(instPrefab, newPrefab, ReplacePrefabOptions.ReplaceNameBased);
57.         Object.DestroyImmediate(instPrefab);
58.     }
59.  
60.     return;
61. }

This creates a new prefab "next" to the imported SVG, and it has each layer as a separate child GameObject, as well as having saved the sprites to disk as well.

Next step is to see if we can get the layer names from within the SVG (via SceneNode?) in order to properly name the child GameObjects and Sprites. Not sure if that's feasible right now or in the future.

I also haven't tested this on more than a trivial SVG – there's the SVG offset bugs that are mentioned up above that worry me, and of course I guess this being a preview extension, it's subject to change.

 

@mcoted3d: Thank you again for your hint on the geometry bounding boxes. Now everything is fitting together like in the svg import.

Result: SVG import to a GameObject with corresponding meshes and materials for each layer in the SVG.

 

Is it possible to work with SpriteRenderer.Color if you are using SVG files. I am playing around with that right now, but it doesn't see to be working for me..?

 

I also wanted to use the SpriteRenderer.Color so I modified the shader a bit, now it works with gradient and solid vectors.



I just uploaded a small repository here so anyone can use it and improve the shader as they wish, I noticed that I broke the flip functionality but I fixed it by using transform properties, I also needed to skew the vectors so I added that to the shader as well, here's the shader only:

Hi, loving the vector graphics preview, thanks! One quick question. When importing svgs from Adobe Illustator, they don't scale when adjusting the PPU settings. This works when importing them from photoshop. Is this a bug or am I missing something? Many thanks!

 

I see, I use "export selection" so I have to open the exported SVG then save and uncheck "Responsive" in the advanced settings. Hopefully one day the unity importer can strip the viewbox attribute. Thanks for the heads up!
