Can't help but stare in awe at your progress every time you post. Incredible!
I wanted to ask how you get your heightmap edges so clean? Once you submitted, may I ask for a quick step-by-step on how your layers are set up on a cog or something. When I did mine, the cog seems to bulge out from the mesh, rather than have a hard edge (even with hardness set to 1).
Cheers! And keep up the amazing work!
