Hello! I’m trying to use the stencil buffer to clip a GLTF on the Y axis. I’m building off of this ThreeJS example: https://threejs.org/examples/webgl_clipping_stencil.html When I clip the torus primitive model it looks great. But when I load the Damaged Helmet GLTF file I get some weird rendering…

that seems sliced just fine to me? also you could do real-time slicing in the shader with no problems and I thought this is what clipping planes do, apparently not? never thought that they use stencils

Seems related and happening on all nontrivial models - 3DM clipping flickering
