Mesh Error | Random Hole?

Solved - will be kept up to help others :+1:

Hi everybody!

Is anybody able to help me? I’ve made a tree mesh, the logs in one mesh and the bush shape in another (check attached images), the log/trunk mesh is fine, but I think there’s a camera error with the bush as you can see straight through it in whatever position you move the camera as? I’ve also attached the .obj file.

Please help ASAP. Thanks!

I think your normals are flipped. In blender, go to edit mode, select everything, and then go to normals → flip.

You can see if the normals are flipped in blender by going into object mode, and then going here:


And turning backface culling on.

Hi there, thanks so much - I’ll try this out now.

I think I know why this is happening.

In Blender, there is an option to make the mesh “negative”. When it is negated, it is like, the outside turns into the inside and the inside turns into the outside.

It’s kind of like flipping it.

The outside (or Shell) of a negated mesh is transparent, and the inside of a negated mesh is visible.

The outside (or Shell) of a regular mesh is visible, and the inside of a regular mesh is transparent.

Is your mesh negated?

Yes, I think it is! Do you know how I make it normal? (lol no clue what the word is, just made my first mesh 30 mins ago)

Yup issa dem good ol normals.

The way I fix them, go into edit mode, press A then shift+N that’s it. Do NOT click fill inside, just unselect all and re export. This is a painful issue happens to a lot of developers but yeah good luck!!

I’ll try that now, thanks a bunch.

I do not use Blender, sadly.

you can try looking it up on google.

Look up: “How to make my mesh negative in Blender?” and just do the opposite of that.
