Hi all, here's a small issue i've been having, want to overlap 2 geometries, boolean them to get rid excessive bits that are sticking out, then apply a surface and render it.

Lets say i have a hemisphere, apply a basic white surface to it, and then i mirror it to make a sphere, and render it, it looks fine.

IF i have a hemisphere, copy it and move it so that the copy overlaps with the first sphere, boolean them to get rid of the overlap…

now when i render this, something bizarre happens. The parts of the hemispheres that were booleaned come out fine. But in and around the edges of the hemispheres render out with a black surface.

Is there something that i have to assign in the boolean to make it render out right? because when i remove the boolean, everything looks fine.

As a general rule boolean operations don't create the type of geometry that should be considered render-friendly.

The more complex your shapes, the worse the issue become.

I would highly recommend rebuilding your surfaces (manually) after a boolean operation.

Thanks for the info, i will do just that!
