Blender Booleans Not rendering properly

(Ra3id) #1


I recently built this stereo stack in Blender. The areas in question is only the mesh that has booleans applied…I believe that mesh has no thickness and is empty, but that shouldn’t be a problem. The boolean when applied seemed clean by my standards…no messy or irregular faces…although it does look like there may be the some n-gons in there? I don’t know…

I tried both OBJ and FBX, and both meshes import with tearing…

I looked around for answers, but none of the topics solved my issue.

Thanks in advance!

Hi @ra3id,

This is actually a polygon tesselation issue.
Boolean operators generate concave polygons very often, that messes up the mesh during tesselation step, when converting thoses concave polygons into triangles.

If you use the Triangulate faces operator in Blender before exporting the scene, it should fix your issue.
It’s available in the operator search (Ctrl+Space and then search for the tool).

I hope it helps :slight_smile:

This fixed it. Big thanks to you!!!


We just shipped an improvement to better tesselate nGons during processing. Uploading models like this should now work as expected.
