Hello I have an issue when I want to render.
This is how I look in the preview.
and this is the final result.
Anyone have an idea of what this is happening?
This type of artifacts (looks like a bunch of triangles) is usually caused by an issue with the mesh itself. You'd have to fix it in the original program you created it in. If you can send the .obj that you imported and the screenshot of the issue to firstname.lastname@example.org I'll have the engineers take a look!
Done. I sent the email.
