Getting ever so slightly closer…! Seems like dumb luck that plugging the normal’s x/y values into the p5.geometry UV’s draws the texture within the form… nevertheless… almost there !

Curious if to do it right and have the texture also around the outside of this object requires the custom vertex class in csg as previously mentioned… ooor… wondered if it’s possible to use a modulate within the parsing of vertices to alternative the [0,0] » [0,1]… etc etc… I know far too little about WEBGL, obj, uv’s etc…
Curious why you had previously disabled the ‘ib’ and ‘ic’ normals? when reactivated, one gets the very smooth materialNormal() shading rather than more polygon style – both interesting, but smooth seems more expected (just tested disabling again with texture applied… and yeah, needs both active to not be pixelated).
