Painting on Textures

Does anyone have or know of a good example of painting one Texture2D on another Texture2D with alpha-blending?

It can use either SetPixels or RenderTexture (Pro only). I’m just looking for something to get me pointed in the right direction either way for starters.

Thanks!

Thanks, Fattie. I actually did just that but none of the existing posts have a complete or working example.

Use
Vertex Paint
