Can a back face culling work on a simple cube? We’re trying to build a room and instead of building different planes into one, we’re using a cube.
Please advise what’s the best option.
*Correction*it seems that my backface culling doesn’t work at all. When the cube was created and windows added as a separate object- nothing was happening besides window dissappearing when backface culling is on.
Backface culling works. Be aware of the Normals!
Backface Culling off:
And the same with Backface Culling:
Thank you very much @spikeyxxx. I have tried to do exactly the same but it doesn't seem to work at all. Am I forgetting anything?
Right, when you enable the Face Orientation, you will see the Faces that are facing you ('front-facing') in blue and the ones that are facing away from you (meaning you see the backside of those Faces) in red.
What I did in my screenshots was turning the default Cube 'inside out'.
Select all in Edit Mode and press SHIFT+N:
and then check 'inside' to flip the Normals:
Now you can see the effect of Backface Culling.
It's a bit tricky to explain, but I hope this helps.
Feel free to ask again if it still isn't clear :)
