Artifact/Error with transparent 3D model

Hello everyone

I’m working with a 3D model, but when I try to make the model transparent, strange errors appear (see images 1 & 2). Many small triangles form within the model and it looks different depending on how you change the camera

I have already tried to solve this problem with depthWrite and various blending modes, but unfortunately this did not help much. With depthWrite = false, the transparency looked good, but the surface was very flawed as a result (see images 3 & 4)

Thank you in advance for your assistance!

Looks like a corrupted model. But besides that, if the model has multiple overlapping transparent parts, it will unfortunately render poorly - regardless whether there’s depthWrite enabled or not. This may help eventually (demo), but it’s not available yet.

Thank you very much for your advice!
I am currently testing it with a new model.
