Opacity map with depth?

[Jpjapers]

It's probably would be best to attach scene for inspection. Most likely you did some mistake here, as i see no reason for such setup not to work.

Its the translucency applied to the acrylic material. I removed it and it worked fine. There are various major artefacts when using anything more complex than basic primitives however.
Ive noticed you get a really thin slice of the base object material before it changes to the inside edges. Is there a way to control the thickness of that edge?

Distance map is known to produce artifacts in some cases. If your cutter has sharp angles, you can try to add tiny amount of chamfer and see if that helps. Also try to subdivide intersecting objects - that might help also.

Are you using round corners on that material? Try to remove it and see if thin line disappears.
