[FREE]MicroSplat, a modular terrain shading system for Unity Terrains

Look at the top of your editor, if it says "DX9 or "DX11 emulated via DX9" then the editor is running in DX9 which doesn't support texture arrays. If not, check to make sure your not set to graphics emulation mode.

 

Thanks!

It indeed says DX9.. But the DirectX Diagnostics Tool says I have DirectX 12...

Edit: Well, changing it in Player Settings helped. Thanks for pointing me in the right direction!

 

Sorry for double-posting, but I think you might have missed my other question before, because I edited it in after the fact:

Multi-editing doesn't seem to work with MicroSplatTerrain. The script MicroSplatTerrainEditor seems to have the CanEditMultipleObjects attribute, but if you select multiple objects and assign the Template Material, it only gets assigned to one of them.

I believe I had this problem with my own code as well at some point. I forget the details, but I think the OnInspectorGUI was still applied only for the "real" selected object or something. And it was my job then to apply the changes to the rest of the objects manually...

 

Yeah, that's most likely because it uses a custom editor, and once you use a custom editor, you have to driver everything through serialized property or use hacks to apply changes across the selection. It's on my backlog to fix this, but not super high priority yet.

 

Hi there, i'm having some issues with Microsplat system.

1) This issue is with another shader asset called Stylized Water:
As you can see in this screenshot there is no intersection of the water with the terrain and also some other things are disabled:


And this is with the standard shader of terain:


2) The other problem is that i'm seeing objects under the terrain as you can see in the next photo:


Cheers!

 

I’d check with the other asset author and see if he has some special requirements for his effect.

 

Hi, thanks in advance, how about the transparency issue?
I think all of this is related to depth buffer.. But i'm not sure.

 

MicroSplat doesn't use the depth buffer in any way, however, most water effects will use the depth buffer for things like shoreline, so there's a good chance you are correct. It could also be possible that the water effect is set to draw earlier than it should be, but without seeing the shader or scripts it's hard to say..

 

Yeah, the water writes to depth buffer, however i have it enabled on the camera.

Let me know what do you need and i will try to help you.

Edit: About the water problem i contacted the author, and i explained the problem to him.

Edit2: The author took a quick look at the problem, however he will take a deep look when he can.

 

About the transparency issue i found that is related to the shadows, however i'm not sure what's causing this.

With Shadows:


Without Shadows:

 

Send me the scene and I'll take a look- but there's nothing in MS that should make it to not write to the depth buffer..

 

Hi there, my project is really big actually : / I will try to make a simple scene.

If i use your MicroSplat material of the example folder in my terrain there is no transparency issues, maybe it's anything related to the TextureArray.

Things i already tried:
-Change textures. (It doesn't work)
-Remove Textures. (It doesn't work)
-Recreate the shader and the data (It doesn't work)
-Changing settings around. (It doesn't work)
-Reinstall MicroSplat (It doesn't work)
-Tried with your material and data (It works)


Also amazingly, with your material works the water too.


Edit: I managed to workaround the bug by duplicating your example material, however i believe that is something wrong with my splat count, i will redo the texture paint tomorrow and see if that fix it.
Probably the grab textures from terrain button got a corrupted texture of my terrain data unfortunately.

Sorry to bother by the way!

Thanks!

 

Hi,

I had the same problem as DevKirbyrawr on a newly created terrain (shadows could be seen through the terrain, and also no shadows were projected directly on the terrain) in the latest Unity version 2017.2.0f3. However, after I removed the MicroSplat script from the terrain and deleted the MicroSplatData folder, and then added the script again and re-generated the shader it worked. It could be related to normal maps, because I first didn't include any normal maps, or hadn't marked the texture as normal, or because I experimented some with reverting to the old terrain shader and then back again. It's a very simple terrain with just two textures.

Just a side note: Have you considered releasing an addon to MicroSplat to allow more than 16 textures? I'm doing low-poly, so don't really need all the features of MegaSplat, but I'd love to have a greater number of texture.

Thanks!

 

That's odd- I can't imagine what would cause that to happen, but if you manage to get a clear repro of how to make it happen please let me know. MicroSplat is limited to 16 textures because Unity's toolset is limited to 16 textures - To go beyond this, you basically have to replace the entire toolchain and use a different technique, which is basically what MegaSplat is.

 

Hi there, for reproduce it i only created a terrain, used microsplat converter and no more, i didn't fill the normals or anything.

Edit: Also doing the work around works but as soon as you put more textures it will break.

Except this, your system is really good, i bought triplanar module and it made me happy to see how well it's.

 

So, I don't seem to get the shadow issue at all - but if I add a texture to the TextureArrayConfig, I have to press Sync on the MicroSplatTerrain component to get the terrain painter to update with new textures. I can fix this for the next patch, but for now, pressing sync will update the terrain with the new textures after they are added to the array and you press Update on the array.

If one of you can send me a scene with the shadow issue that would be really useful.

 

Ahh, I see. I will likely get MegaSplat in the long run anyway, but thanks a lot for releasing this for free! I'll definitely let you know if I manage to reproduce the error.

 

I sent a repro project with steps to reproduce the issue and a screenshot to your gmail, let me know if you need anything.

Cheers.

 

I am having the same shadow issue as DevKirbyrawr. Object shows through terrain and shadows aren't projected, as shown below (new project, terrain on left was converted to Microsplat, terrain on right is normal Unity terrain, only objects on scene are terrains, cube and directional light):



I was going to send a repro project but I see DevKirbyRawr already did. If necessary I can provide further information or examples. It does work normally if, as DevKirbyrawr did, I use the material given in the Microsplat example.

 

Fixed- if you want to fix this yourself and not wait for the UAS to update the package, open MicroSplatShaderGUI_Compler and change the WriteFooter function to:

Code (CSharp):

1.  
2.       void WriteFooter(string[] features, StringBuilder b, string baseName, bool blendable)
3.       {
4.          if (blendable)
5.          {
6.             b.AppendLine("   CustomEditor \"MicroSplatBlendableMaterialEditor\"");
7.          }
8.          else if (baseName != null)
9.          {
10.             b.AppendLine("   Dependency \"AddPassShader\" = \"Hidden/MicroSplat/AddPass\"");
11.             b.AppendLine("   Dependency \"BaseMapShader\" = \"" + baseName + "\"");
12.             b.AppendLine("   CustomEditor \"MicroSplatShaderGUI\"");
13.          }
14.          b.AppendLine("   Fallback \"Nature/Terrain/Diffuse\"");
15.          b.Append("}");
16.       }

 

Can confirm fix works. Having no problems now. Thanks for the quick response.

While I'm here, let me ask a question about one of the MicroSplat modules; is the Alpha Hole purely cosmetic or does it also make a hole in the terrain collision? I checked the documentation but found nothing specific on it.

 

I don't have an example currently included, but wrote an example one and just haven't had a moment to see if it works yet:

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class AlphaHolePhysics : MonoBehaviour {
7.  
8.    public class ExampleClass : MonoBehaviour
9.    {
10.       public LayerMask disableLayer;
11.       public Terrain terrain;
12.       public Collider terrainCollider;
13.       public string tagName = "Player";
14.  
15.       void Start()
16.       {
17.          if (terrain != null)
18.          {
19.             terrainCollider = terrain.GetComponent<Collider>();
20.          }
21.       }
22.  
23.       void OnTriggerEnter(Collider other)
24.       {
25.          if (other.CompareTag(tagName))
26.          {
27.             Physics.IgnoreCollision(other, terrainCollider, true);
28.          }
29.       }
30.  
31.       void OnTriggerExit(Collider other)
32.       {
33.          if (other.CompareTag(tagName))
34.          {
35.             Physics.IgnoreCollision(other, terrainCollider, false);
36.          }
37.       }
38.    }
39. }
40.  

 

That should work , i have the same system in my game and it works good.

 

Thanks for the quick fix, this also fix the water issue i was having!

 

Hi, Mr Booth! After I updated MicroSplat recently, the triplannar function seems gone on the blended object.. Do you have any clue about this?

 

I'm not sure if this is the case, but you have be wait with updating the core module until the additional modules are also updated (to the same version as the core)

 

I'll check it out- the recent update was a minor one that shouldn't break compatibility between modules.

 

Ok, so I see what happened here. When snow is on, you want to use the terrains normal so that snow appears on the edge of the objects, so what the change did was blend the normal across the blend area. However, this means the triplanar's normal is also blended, causing it to blend between the terrain (top down mostly) and triplanar projections over the area, which in your case is undesirable. So what I've done is to add a second terrain distance to control this blending. With it, you can make the blend area for the normals very small, while the blend area for the texture remains much larger. I'll ship a patch for this tonight when I get home (doesn't break compatibility with core, so doesn't require a big update).

 

I just noticed that Interpolation is now an option for per-texture -- that's fantastic, I was gonna ask about that!

But I'm having a new issue as I set up MicroSplat in a new project -- I get this error whenever I toggle a feature on or off. Main MS features still work despite the error, but the per-texture settings don't work at all. Any idea what's wrong?

EDIT: On Mac, 2017.1, tried both OpenGL and Metal editor.

 

Never seen that before. Does it show any of the MicroSplat files in the rest of the call stack? The smallest texture I generate is 16x16..

try changing line 114 in MicroSplatTerrain.cs to:

Code (CSharp):

1. terrain.terrainData.baseMapResolution = Mathf.Max(16, oldBaseMapSize);

I think when Unity goes to generate the basemap which it uses for it's distance rendering (Which microsplat does not use) it's getting set to 0 pixels in size, and Unity is no longer checking that value before it tries to create a 0 pixel image.

 

Thanks...but that didn't help. Same errors, though this time they don't mention MicroSplat, so maybe that was a red herring. But these errors do appear whenever I toggle MS features on or off.

Spoiler

What size does the terrain say the basemap is set to? Both errors seem to be with basemap generation, which Unity triggers any time a shader on the terrain is changed, which is what happens when you toggle an option and MicroSplat regenerates the shader.

 

Base Texture Resolution is 16.

 

Are any texture's assigned to the terrain (unity's UI)?

 

yes, the terrain has for splats assigned to it, on the terrain textures pane.

 

Can you send the scene over? Maybe it'll repro on my mac.

 

I'll try to extract something I can post for you.

 

I haven't got the snow module, so I'm not sure if I could understand this.. Maybe it's time to give it a try on the next fix

 

No, it was a fix to the snow module so the snow would object-blend with the terrain too, but this broke triplanar working the way it used to (with or without snow). Anyway, you'll be able to control the distance of the blend (like before) but also the distance of the normal blend, which will allow you to get the old behavior as well.

 

I'm trying to set up River Auto Material on my terrain, and having the same problem that DevKirbyrawr reported above -- the river loses transparency when I assign my MicroSplat material to it. So then I tried his solution -- assigning one of the MS demo scene materials/data files, and that worked! But then if I make any changes to that material/shader (change number of textures, or toggle on any of the features), then the river loses transparency again. I've tested that several times (reverting the demo files) and it's totally replicable for me -- as soon as I make any change that triggers the MS shader to regenerate, the river loses transparency. Any suggestions?

 

Did you get latest of core?

 

I thought I did, but I see there's a new one (you really crank those out!), so I got that, and initially the river had transparency, but loses it as soon as I make any changes to the material settings. (And I'm definitely current with all modules now.)

 

Can you look in the output shader files and see if they have Fallback "Nature/Terrain/Diffuse" at the bottom?

 

They do not -- I see that fallback line in the un-regenerated shader for the Core demo scene, but it's not in the other shaders that have been regenerated.

 

Hmm, I wonder if the UAS didn't prop the latest build? If you go into MicroSplatShaderGUI_Compiler and swap the write footer function to this one:

Code (CSharp):

1. void WriteFooter(string[] features, StringBuilder b, string baseName, bool blendable)
2.       {
3.          if (blendable)
4.          {
5.             b.AppendLine("   CustomEditor \"MicroSplatBlendableMaterialEditor\"");
6.          }
7.          else if (baseName != null)
8.          {
9.             b.AppendLine("   Dependency \"AddPassShader\" = \"Hidden/MicroSplat/AddPass\"");
10.             b.AppendLine("   Dependency \"BaseMapShader\" = \"" + baseName + "\"");
11.             b.AppendLine("   CustomEditor \"MicroSplatShaderGUI\"");
12.          }
13.          b.AppendLine("   Fallback \"Nature/Terrain/Diffuse\"");
14.          b.Append("}");
15.       }

then it should write that in there when you recompile the shader (toggle an option). I'm doing another push tonight, so hopefully it'll come through this time.

 

My apologies -- we're using MAD Compile Time Optimizer and it moves files around, and usually the Asset Store finds those files when importing updates, but apparently not this time, so I was still using older versions. I fixed that and now all is well. Sorry for the trouble.

 

Got your point, Mr Booth. Also, when I use the slope feature on the blended object, there is a distortion effect on the object surface that moves with the camera. Could this be the same problem due to the snow module changes? Can't post you a screenshot because it's not on the same machine, but if you are not sure what I mean, I'll try..

 

Don't think so - it should be totally stable.
