I popped over to the wiki for Sync1b’s neat-looking LayerShader but am having trouble getting it to apply anything but _MainTex. The mask doesn’t seem to be working.
I know nothing about shaders, so if anything strikes you as immediately wrong about the screenshot below, please forgive me!
That shader uses alpha channel of PathMask texture to interpolate between the other textures. You should set “generate alpha from grayscale” in import settings of your texture.
I also updated the wiki page of that shader to use less funky combiner setup and added some notes.
