I am working on a bedroom project in Blender while following a tutorial. I'm not sure what I did wrong, but while attempting to color the walls of my bedroom, I realized some of the parts were- folding in on themselves?

I'm not sure how this happened, I recently merged the vertices by distance to fix a different issue; would that have anything to do with it?

Here is the blend file: https://blend-exchange.com/b/OsmXJW7G

I feel a bit silly asking another question only minutes after my last got resolved. I'm just not sure what else to do.

Help and advice very appreciated!

  • Hello, for the moment you still have overlapping vertices, so you need to Merge by Distance, and also you have a Bevel modifier, which creates bevels, but I'm not sure what you mean by "folding parts" (but I can't select these half faces like you show) – moonboots Aug 17 '22 at 08:20
  • I think I figured it out! I removed the Bevel modified then re-added it, but instead I set it to "by vertices" rather than "edges". Thank you for the help! – Scarxiett Aug 17 '22 at 08:25
  • oh ok yes it's the Bevel modifier that created this effect for some reason – moonboots Aug 17 '22 at 08:27
  • Well, are you sure you want to bevel the vertices? What was the problem with the edge bevels? – moonboots Aug 17 '22 at 08:29

  1. check your face orientation and repair it -> if you click on "overlays" -> check "face orientation": red means: wrong orientation.

To repair, select red object, TAB -> edit mode -> A (select all) -> Shift N

if all is blue...

  1. delete double faces -> select object, TAB -> edit mode -> A (select all) -> M -> merge by distance

after that your problems should be gone.

You have internal faces which is considered non manifold geometry and messes up the Bevel Modifier causing your distorted geometry.

And don't forget this side as well. Once you have deleted these internal faces, your Bevel Modifier will work perfectly :)

    +1 This probably happened because you Extruded > Changed your mind > right-click canceled the move (Leaving the extruded geo in place) > Decided to inset > Inset the now doubled face you had selected. Remember that when you press E to extrude you are actually doing two things at once: Extruding the geo and then moving it. When you right-click to cancel you only cancel the move part. Be aware of that. – Jakemoyo Aug 17 '22 at 09:24
