I've searched a lot and I didn't find anything useful for resolve of my problem. I believe you can help me with it. My project displays a model with heat distribution on the surface. An object is builded via code. And I have normals for each triangle of this object. I need to build normal map and temperature value map by shader on the first render pass and then use this maps on the second pass. I used to did it byWebGL, but I don't understand how can I do it with Unity?
