Oh awesome. I do wish I could remember all the nice math tricks. But sadly there is too many complicated things for me. I do really like math, so thanks for sharing Still I wish there was a way to actually paint directly on the surface. And use direct UV space of the ground instead of world space.
Glad you got use out of it. Hope to see some screenshots of that.

To be honest, it’s not working too well on the landscape which is not covered with snow but rather sand What I mean by this is that I can’t render decals without landscape but with landscape they are mixing with landscape albedo color and then I can’t cleanly get prints out of SceneCapture.
I’m just doing a prototyping now as proof of concept and most likely I’ll have to make a copy of the landscape, with a completely black material, under the main landscape, just to place white decals as a mask.

Did you used content of alpha channel of Scene Capture? Cause for me it’s all black, nothing is getting rendered into it.

The better approach is a custom shader to render both landscape and decals, on demand into a different render target, outside of the main render pass but that requires some C++ code so won’t work with just a native version of the engine.
