Question Sprite set color of vertices on individual meshes.

I'm trying to assign vertex colors to Sprite, different for each instance.

I've managed to write a script that sets vertex colors for Sprite mesh:

Code (CSharp):

1.  
2. private void SetVertexColors(Color32[] _vertexColors, Sprite _sprite) {
3.         // set Colors NativeArray from Array
4.         NativeArray<Color32> _vertexColorsNA = new NativeArray<Color32>(_vertexColors, Allocator.Temp);
5.  
6.         // set Vertex Colors
7.         _sprite.SetVertexAttribute(VertexAttribute.Color, _vertexColorsNA);
8.  
9.         // dispose NativeArray
10.         _vertexColorsNA.Dispose();
11. }

The issue is, vertex colors are changed for every Sprite instance:


Is there a way to make vertex colors individual for every Sprite?
From what I know, Sprite Renderer sets vertex color with Color on individual level somehow. How to copy that behavior?

 

I imagine you probably just need to clone the sprite first, then change that clone.

Steps:

- get a reference to the original Sprite
- clone it with

Instantiate<Sprite>( original);

- modify that copied Sprite
- assign that copy to the SpriteRenderer

 

Thank you, that actually works!

One downside of this is - Sprites no longer are 'saved by batching', which is real issue for eg. grass objects.

 

[edit] it batches nicely, 'GPU instancing' na material need to be turned off.
