!div style="display:none"!fjrigjwwe9r2content:tip!/div!!div style="display:none"!edf40wrjww2content:tip!/div!This is just a little tip from the Stratalist.

! I have an extruded rectangle, I subtract a
! smaller extruded rectangle, I then make a
! extruded rect.
! to fit inside of the boolean, but when I render it
! weird dark areas appear across the infill rect.
! If I move the infill out of the boolean they
! render as a frame and a solid rect.
! What's goin on here?

The answer from Jean Probert:

Initially, all Boolean operations except cut are actually boolean renders, so that you can undo later if you want. Because of this, you sometimes get render
errors such as you describe.

If you are sure you want the boolean subtract you did to be permanent, select the object and convert it to a polygon mesh. Try your render again, it should work properly.

Also from Reagan Johnson:

And if you're not sure, make a copy first! Once you convert to polymesh, there's no turning back. I usually just copy, paste, then hide my original booleaned shape for safe storage. You can always delete it later.
