Really weird issue with not rendering faces of cubes, procedural generation

this didn’t happen before I added randomization to the placement and scale of the meshes. does anyone have an idea what’s wrong?

Note* it doesn’t render what I’m looking at in any direction (visual effect is the same on all angles basically)

My third bump

Inverted normals? Or negative mesh scale? Although negative scale generally works ok. Hard to tell without seeing how the scaling is done.

They’re instanced meshes, and they do have negative scales.

What is stopping you from trying non-negative scales and eliminating / confirming this as an issue? If you’re using (H)ISMs, that’s very likely to be the culprit. Judging by what is shown, there’s no need for negative scale here, but perhaps you’re planning something funky later on, ofc.
