Holes in 3D Models

Troubleshooting graphics

Hey Guys, can anyone imagine why most of my 3D Models have holes in them? It looks like this:

Those Models are exported as .obj with .mtl files and use .png Textures. All of them are in the Opaque BucketQueue.

Thanks in advance

Could be that some of the faces are wound backwards. You could try to change the face cull mode to see.

If they are built in blender, use show normals to see if they are facing outward. You can try recalc normals, however, this doesn’t always produce the desired effect and often you have to select the problem faces and just flip them.

Thank you. I tried that, but it didn’t change anything.I’m pretty sure that it is because of the partly transparent png texture. I changed the texture to another one (a weird one :smiley: ) and it wasn’t that perforated. Do you know how I can change that weird behaviour?

@t0neg0d
thank you, I will try this in a moment

kind regards

Well, transparent textures with holes in them will end up being holes in the model. So that could be your issue.
