Can someone explain how exactly we are drawing on the Render Target? In the Stream they only say: “yeah, here is the SplatMaterial and you can use every other brush you want”. Nice jokes that you can draw unicorns and stuff, but it feels like you also have no idea how exactly to accomplish this. Especially the SplatMaterial was poorly covered. Can we get a full explanation, saying we raycast on the plane, get the UV coordinates and paint on it doesn’t help much. What is all the math involved in the SplatMaterial, how do you need to change the material to make those lovely unicorns you were talking? In the Stream you were only reading the nodes, no explanation at all, only stuff like “bascially, we need this to do stuff”. <3

All you have to do is change the Texture that is in the Splat Material and you will have a new effect when you use it.
