Title: Slicer material artifacts
Post by: 3dsloth on 2022-04-18, 23:39:57
Using the slicer material to boolean objects seems to leave strange artifacts.

Haven't seen that before, best bet would be to use "Send a request" over at support.chaos.com, when you do that, let us know which version of C4D, which OS and version of OS, and attach the scene file so we can explore it directly.

Also, just to be clear, when you say "to boolean objects" - you aren't actually doing any sort of boolean operation in C4D, right? You are just applying the Slicer material to the object you want to use to do the cutting-away, and then nothing more than that (and positioning it in the right place of course :) ).

Thanks, and no, I wasn't using any actual boolean operation in C4D. Just the slicer material on a cube object.

Thanks for confirming! If you can send in the scene, that would be great (and ty if you have already done that :) ).

Hi,
I encountered a similar problem and I think I figured it out.

This happened for me when the Object I am slicing has no thickness, sometimes it shows the overlapping backfaces of the subtraction object with the slicer material, but only the inner faces. In some cases it glitches out and shows there artifacts like the OP encountered.

So what I did to fix it was, select the object and give it a thickness, in my case I could use a cloth surface with a 0.1 thickness.
I cant provide a scene file, since the objects are confidential.

As it turns out the normals in one of the objects were reversed so switching them back fixed the issue.

Thanks for providing your solution with us and others.
