Need to paint a happy trail on mesh that’s textured? Try Vertex Painter. It’s made by the same guy who makes Megasplat.
Basically, I just followed these steps:
- Select the mesh
- Chang the shader to
VertexPainter/Splatblend_2layer - Set the First Albedo/Height to my Trail Texture
- Set the Second Albedo to the main (original) mesh texture
- Paint Black to add in the trail
- Paint White to add in the main mesh (erase the trail)
Ten minutes in and it’s still working, so that’s a good sign.
I don’t know how to make this work for actual Vertex Painting, but for now, I’m just going to hope that I don’t need to. :-)
Stuff That Didn’t Work
Polybrush
This was my first try and it really should have worked. But instead, it either failed to work entirely, or it would crash and lock up Unity after working for a few minutes. I tried this on both Unity 2017.4 and 2018.1 – same result each time.
P.S., the only way to get it to kind of work was to use the Polybuilder shader NOT the Polybrush shader.
Other stuff
I tried a couple of other things, but I forogt what they were now… It was a whole day of excruciatingly slow trial and error.
