[RELEASED] 2D/3D Paint

Hi! Thanks for your question!

Yes, you can replace methods for new input system in InputController.cs, but if you want to draw frame rate independent, it requires to modify logic of drawing points and lines as they uses only one input data per frame. This is in my todo list for version 2.6

 

Yep, I have the new input system running and so far so good. I'm running into an issue with painting though that I'd like your feedback on.

My intended usage with 2D/3D Paint is to just paint greyscale masks at runtime. When painting with the default settings (ARGB render texture, 8 bits per channel), painting soft strokes is fairly low quality. Banding occurs or otherwise poor brush painting results. Do you have any suggestions? Maybe the painting should be done without gamma correction?

If i switch to a 16bit render texture, the greyscale reproduction and brush stroke softness is much better but of course the framerate takes a hit. Any help is appreciated!

 

Which platform and graphics API are you using? Can you share with me your paint object shader?

 

Version 3.0 released!

What's new:
Core:
- New features: layers and blending modes. Asset works with layers and supports 26 blending modes;
- New tool: grayscale - tool for discolorating parts of the texture;
- Undo/Redo functionality was rewritten from scratch and now supports layers parameters change;
- Added support for the new Input System and Pen support;
- Added support for submeshes and UV channels;
- Added 48 new brushes;
- Added support for perspective cameras when using the SpriteRenderer component;
- Added ColliderPainter component to paint with collisions;
- Added ability to set default texture color;
- Fixed brush preview offset;
- Fixed bug when Canvas UI didn't lock input interaction in case of RawImage painting;
- Optimized memory usage for tools;
- Improved VR support.

Editor:
- Added CustomEditor for Settings.

Other:
- Updated Manual;
- API changes (see "v.3.0_API_Changes.pdf" for details);
- Bug fixes.

 

Congratulations! 2D/3D Paint is now the first and only painting asset in the store to feature layers and blend modes.
Maybe the marketing material should promote and feature this more, I am sure a lot others look to this as well!

 

Really awesome update! Even the UI is neat. Am gonna buy this very soon.

Have only two suggestions:
- A thing that's really missing compared to regular art programs: An "airbursh", aka a brush with very soft edges. Maybe the main brush can do that just by providing a simple fading circle? Procedurally generated in the shader might yield best results.
- The blur brush is really cool but is there a way to avoid it pulling the color from the layers beneath onto the blurred layer?
Just blurring the current layer and change transparency to blend with the underground would be more intuitive (and what I'd need for something I have in mind).

In every case keep up the great work on likely the best drawing asset out there!

 

Thank you! I never thought about it, and it sounds so cool!
I plan to do another promotion video focusing on the layers feature

Thank you!
- For "airbrush" you can use Default Paint Mode with small brush opacity value, hardness ~0.15 and turned on flag "Draw On Brush Move" in the tool settings, I attached an image, is that what you need?

Spoiler: Example

- Yes, you can turn off flag "Use All Active Layers" in the tool settings. In this case only active layer will be blurred
Thank you so much, I have huge plans to improve it and add new features

 

I am guessing the next thing in line is image effects & adjustment layers?

 

Nope, but I'm sure this will come as a pleasant surprise

hello @kmedved

I had recently purchased this tool, I want to know if we can create a mechanism through which user can paint using Raycast mechanism lets say user has a gun, the raycast would be done from the nozzle to say x distance and if it found the objects is paintable then it would paint the object. Hope to hear from you soon.

 

Hello! Yes, you can paint with collisions using "ColliderPainter" class or create similar functional to paint with raycasts. Also, drawing from code might be helpful: https://unitymedved.bitbucket.io/XDPaint/3.0/Docs/index.html#drawfromcode

 

Hello @kmedved Is there any way to paint two different meshes simultaneously? let say I have a spray gun and some part of water is on the half part of first mesh and other on another half but only the one half is painting, Do you have any solution for that, please guide me.

 

Hi! Yes, you can create the PaintManager for each mesh. Note that it will work if you use different materials for each object.

 

Hii, I already have paintmanager on both the meshes and different mateial as well but still facing the same issue, Any other solution?

 

Can you send me a small Unity project with an issue?

My email: unitymedved@gmail.com

 

Nevermind @kmedved I had solved the issue by taking a combined mesh, Another question is that any way to control the speed of painting?

 

Can you tell me, please, what you mean by the speed of painting?

 

Kind of progressive painting Paint as per time, Suppose if we have to brush on a model it will not directly paint as whole but after 3 to 4 hands of the brush on the model the color will be seen as whole

 

To achieve it, you can set the brush opacity to ~0.25-0.35 with Additive Paint Mode, or ~0.05 in case of Default Paint Mode

 

thank you, I used opacity as a speed parameter

 

Version 3.0.6 is out!

What's new:
Core:
- New tool: BUCKET - tool for filling texture parts with selected color;
- Decreased memory allocations in Runtime;
- Fixed VR Input.

 

Helllo @kmedved I don't know exactly what it is but suppose if i have two models if one model is exactly behind another and if we apply the paint then the paint will be applied to both.
Note: I have different material on both models and different texture as well.

 

Hi! This is what I'm working for right now for the next update
Please, write me an email and I'll share my current implementation

My email: unitymedved@gmail.com

 

sure i will mail you the same

 

Hello, the version I use is 3.0.6, and I use SkinnedMeshRenderer to paint the object. When I change the position of the object in transform, the drawing ray can only recognize part of the object, and some parts cannot be drawn. This problem does not exist in 3.0.4.

Here, the left arm cannot be painted.

 

Hey, thanks for your reply! I already fixed it and planning to release version 3.0.7 with a fix soon, for now, can you import the attached .unitypackage and check it, please?

 

Thank you! It's good, and no problem now

 

Hi! I want to paint together and use this wonderful asset to access the multiplayer online function. Is it difficult to do so? Can you give me some advice? Thank you so much

 

Hey! Thanks for your question!

If you need to draw using a few online clients, subscribe to events of drawing lines and dots (PaintManager.PaintObject.OnDrawPointHandler and OnDrawLineHandler events), then send the data to clients and reproduce each action from received data. Also, you can send other data such as brush parameters (size, color, angle, etc.), selected layer index, etc.
This approach minimizes traffic and gives you the fastest way to achieve multiplier painting.

How to draw from code you can read here: https://unitymedved.bitbucket.io/XDPaint/3.0/Docs/index.html#drawfromcode

 

Version 3.0.7 is out!

What's new:
Core:
- New features: Brush and Bucket tools support painting using pattern texture! You can also control the scale, angle, and offset!
- New feature: RaycastController can use Depth Texture to prevent paint on the multiple PaintObjects at the same time;
- Fixed a bug when Undo/Redo system would clear a layer if the order of the layers was changed;
- Fixed a bug when Undo/Redo system invoked PaintManager.Render() multiple times per action;
- Fixed a bug when SkinnedMeshRenderer has incorrect boundaries;
- Fixed a bug where painting on the SkinnedMeshRenderer would not work if the position was changed;
- Fixed memory leak when a material field didn't have the source texture.

Editor:
- Added PropertyDrawer for ToolManager;
- Added the ability to manage settings for each PaintManager tool;
- Tool settings were rewritten from scratch and now can set Texture fields;
- XDPaintSettings now shows the current version of the asset.

Other:
- The demo scene has been updated, and the user can now invoke the context menu with the right mouse button to manage the settings of the selected tool.

 

Thanks for your answer! I will try it. Awesome new version update!!!

 

Thank you so much for your suggestion! I tried it and it's pretty good! but i ran into a problem

I send the data to other clients in the OnDrawPointHandler action, then other clients reproduce each action from received data as shown in the picture below, in which the OnDrawPointHandler action will be called when Render() is executed, and then the receiver will send the data to the sender. It stuck in a loop.

Is there a suitable place to get the data and send message to avoid re-sending message when draw from code?

 

Hey! Thanks for your question!
You can add a flag to avoid the loop stucking, for example:

Code (CSharp):

1. using UnityEngine;
2. using XDPaint;
3.  
4. public class SomeClass : MonoBehaviour
5. {
6.     [SerializeField] private PaintManager paintManager;
7.     private bool isReceivingData;
8.  
9.     private void Start()
10.     {
11.         paintManager.PaintObject.OnDrawPointHandler += OnDrawPointHandler;
12.     }
13.  
14.     private void OnDestroy()
15.     {
16.         paintManager.PaintObject.OnDrawPointHandler -= OnDrawPointHandler;
17.     }
18.  
19.     public void OnReceivedDataFromServer(Vector2 texturePosition, float pressure)
20.     {
21.         isReceivingData = true;
22.         paintManager.PaintObject.DrawPoint(texturePosition, pressure);
23.         isReceivingData = false;
24.     }
25.  
26.     private void OnDrawPointHandler(Vector2 texturePosition, float pressure)
27.     {
28.         if (isReceivingData)
29.             return;
30.      
31.         paintManager.PaintObject.DrawPoint(texturePosition, pressure);
32.     }
33. }

In the example, if isReceivingData is true, painting in OnDrawPointHandler method won't be invoked.

Alternative, you can comment line 354 in BasePaintObject.cs to not invoke event when drawing from code:

Spoiler: BasePaintObject.cs

 

Hi! Thank you for your answer! now everything is working perfectly fine!

 

hello @kmedved
I want this specific layer texture during we paint, but I cant able to get the painted texture reference but only the unpainted texture. Can you please tell me how we can get this painted texture reference?

 

Hey! If you need to RenderTexutre of the layer, you can invoke:

Code (CSharp):

1. var layerRenderTexture = PaintManager.LayersController.Layers[1].RenderTexture;
2.  

In case if you need Texture2D, you can invoke (don't forget to destroy it when you don't need it anymore, as it may lead to memory leak):

Code (CSharp):

1. var layerTexture = ((LayersController)PaintManager.LayersController).GetLayerTexture(1);

 

@kmedved But I don't want the non painted texture from this method I am only getting the initial texture that i had applied but instead i want the texture of that layer while I am painting. For eg if on the layer 1 i have some dirt applied now at runtime from that layer I am erasing that dirt so just want the reference of that particular layer texture yeah I also don't want the merge layer texture i.e. texture combination of layer 1 and 2 just want the texture of that particular layer at runtime

 

If you need result RenderTexture, you can invoke:

Code (CSharp):

1. var combinedRenderTextrue = PaintManager.GetResultRenderTexture();

In case if you need Texture2D:

Code (CSharp):

1. var texture = PaintManager.GetResultTexture(true); //argument - whether to hide brush preview

Note that it should be destroyed as texture creation is definitely a possibility for memory leaks in Unity if you're not disposing of the old ones properly.

 

Version 3.0.8 is out!

What's new:
Core:
- New feature: added support for multi-finger allowing users to draw with more than one finger at a time;
- Fixed a bug when mesh bounds size had an incorrect value;
- The events PaintManager.PaintObject.OnMouseHoverHandler / OnMouseDownHandler / OnMouseHandler / OnMouseUpHandler / OnDrawPointHandler / OnDrawLineHandler were marked as obsolete and PaintManager.PaintObject.OnPointerHover / OnPointerDown / OnPointerPress / OnPointerUp / OnDrawPoint / OnDrawLine were added instead.

 

Does it just paint basic color? Or can it paint on normals, too? I am thinking of a more "organic" brush isntead of just a color... thank you for a quick answer!

 

Hey! It paints on any shader texture (except the normal map textures, but I have this item on my to-do list and will be implemented it in future updates). The asset does not paint on vertices or normals, only on textures

 

That would be great, because I might want to use it for blood. Without an impact on the normals, it would not fit my needs 100%, so I hope this will be integrated. Here is an example of what I mean:

https://assetstore.unity.com/packages/vfx/shaders/realistic-blood-shader-218900

I believe that this use case and others of that kind will be very attractive for developers. The question is, if you implement that into your painting asset, or if you might plan a different asset for such uses cases. I don't know how your current asset is structured, I'd prefer an easy integration in general - I assume, that your painting tool is somehow "modular" to use it in such a use case, although I see that it is focused somehow on traditional painting.

Would be happy to know how near you will get to that use case (using also normals), and if I should wait for a new asset or grab it maybe now...

 

It looks very interesting! I'll try to implement it in a few next updates, but currently, I don't have estimates for this feature

 

hello @kmedved Can you please help me with this issue?
As seen in the image , there are two layers on a surface one is dirt and one is cleaned now I am erasing the dirt from the active layer and now the issue which I am facing is that i can't able to get the texture of that particular layer only, I don't want the combined texture .i.e. layer1 and layer2 but the texture of the active Layer, I do get that texture but its not have any progress of my erasing, so in brief i just want the progress of my erasing the active layer and have to apply that texture in my emission map so that only the only dirt part can emit on surface. Hope to hear from you soon!

 

Hey! As I said before in this thread, if you need to RenderTexutre of the layer, you can invoke:

Code (CSharp):

1. var layerRenderTexture = PaintManager.LayersController.Layers[1].RenderTexture;
2.  

In case if you need Texture2D, you can invoke (don't forget to destroy it when you don't need it anymore, as it may lead to memory leak):

Code (CSharp):

1. var layerTexture = ((LayersController)PaintManager.LayersController).GetLayerTexture(1);

 

Hi, this looks like a great tool. Does it currently have the feature to paint on quads/triangles? Other applications, like Blender, have the ability to fill the mesh's quads or triangles with a solid color. This is very useful for low poly texturing.
