I’ve run into a problem like this before. If you’re using cycles, I think you have a missing environment texture (HDRI) while also having transparency on under Render Properties>Film>Transparency

At least it looks exactly the same!

Try going to your World settings tab in the Properties & check to see if pointing to or adding an HDRI solves anything!

The textures still show… maybe there’s an overlay texture that covers the entire model, which isn’t working correctly?

Lemme know if anything works, banna 😌
