Strange triangulation when rendering this model

natman

Hey all,

I've finished up this scene, but when I render it the model looks oddly triangulated. I made sure to scale those faces flat, so I'm unsure why this is happening/how to fix it. There are two instances of this model in the scene and they both have this issue.

Thanks for any advice!

whatever you're rendering it in is probably winding your hidden edges differently from the maya viewport.  triangluate the mesh before export.

Hmm, I am rendering with arnold straight from maya

Did you bake this? And if so, where did you bake this? Remember that Maya uses its own tangent basis, so if you've baked it outside of Maya this could be your issue.

Kinda looks like a locked normals issue but I can't be sure from what I'm seeing.

I checked out the normals and they look fine, but thank you for the suggestion!
