Are there any assets out there that allow painting onto 3d models directly in the engine? Almost exactly how the terrain painting works but being able to paint onto other objects to add more detail quickly. If not this would be an awesome tool for blending in scenes more such as moss growing from a rock onto a house seamlessly.
Hello.
You should try ‘vertexpainter’ on assets store ( it’s free ).
You can set 4 textures to one material , and paint on it.
Did a quick search on youtube and it looks very promising! Will give it a try!
If you prefer using your own shaders(so no changing currently used materials) or bake painted texture I think Surface Painter can be very good for you too:)
