dynamically painting on an object @ runtime

Question

Hello People I am trying to basically make a coloring book, where the user can paint on an object with touch.

I think this would use recasting, but I am not sure how Texture2D.SetPixel works for this v. renderTexture.

Any advice is greatly appreciated

best,

SetPixel method is not defined on RenderTexture class. It's only defined for Texture2D.

But you can always assign Texture2D as a texture on a shader, or you can do Graphics.Blit and copy Texture2D to RenderTexture.

Hmm Thanks Paulius

Seems like a lot of work for a coloring book.

The idea of assigning it to a shader is interesting. Then I could draw on any object using that Shader?
