PBR Heightmap Curved Surfaces
Hello!
I'm having trouble with my PBR heightmap. I've seen on YouTube that it's possible to use PBR to create textures on curved surfaces that have a transparent silhouette. but it's not working for me. My spheres look more like crystal balls. Does anyone know how to get that effect? I'd rather not use gl.material because I want to spare my computer and use GPU because I want multiple of these shapes.

jit.gl.material is probably still your best bet for this in terms of efficiency. It's all done via textures and shaders on the GPU so is quite fast. An alternative is to use jit.geom ops, specifically jit.geom.displace. This will likely give you more control, but is run on the CPU.
The PBR implementation never fully materialized (no pun intended) unfortunately.

I've added a feature request ticket for additional heightmap functionality in jit.gl.pbr.
