I have this on my list for features I want to add in the future. ^^ It is technically possible by using some sort of decal which is placed inside the heightmap buffer, similarily like it's done in Unreal Engine. The only disadvantage is that I can't paint.
"best renderers out there, if it's used correctly" Do you plan to write tutorial or smth like that to share your knowledge? It would be extremely helpful for anyone who tries Godot for 3D games
Or maybe just a video where you expand on that? I have very little knowledge when it comes to stuff like that so I would love to hear what an expert has to say on these things.
"It also has one of the best renderers out there" Is it? The general consensus is that the current renderer is a joke in comparison to the 2 big game engines.
