I tried to use a bevel modifier and then there one point in the object has weird face. I tried to erase each face and combine differently but no matter how, this shows up again. All faces are directing outside correctly. How can I remove this black/gray face? Why this happens?

  • $\begingroup$ That is probably caused by that triangle fan. Try converting it two quads, and it may solve your problem. May also be caused by overlapping geometry $\endgroup$ Oct 26, 2016 at 19:04

    $\begingroup$ @Duarte Farrajota Ramos I tried that too, it changes slightly but the face is still there. but I could solve by limiting angle in the modifier. Thanks for your help! $\endgroup$

  • $\begingroup$ Isn't there a partially connected / deconnected face inside ? You could check that quickly by deselecting all in Edit mode and in Vertex / Edge selection mode running Ctrl+Alt+Shift+M. $\endgroup$

I could solve it! If I limit bevel by angle in the modifier, the weird face disappears.
