Missing poly's on imported model.

Unity Engine
1

Okay… let me explain what’s happening:

I’m importing an fbx, which is a biped rigged with a physique modifier. under the physique i have unwrap uvw.

when i import the above, its missing polys around the throat area. when i import it without a uvw map its fine, no missing polys but now i have no uvw map :frowning:

as you can see in the image, for no reason the polys are gone. but show up in 3ds max.
for some reason the arm on the right is pushed inwards, which is a question for another thread. :confused:

does anybody have any idea how i can fix this?!? also on a side note, anyone know why the arm is being pushed in and moved from its rightful place?

Thanks!

your normals are flipped on the polys you don’t see in unity.

Turn on Backface Cull in Max and see if they vanish in Max (select object, right click > Properties > tick Backface Cull).

Looks like the normals are just flipped so their drawable surface is pointing inwards. You can fix that by selecting the polygons and clicking the Flip button from the command panel on the right.

Also try collapsing the UVW Unwrap modifier down.

As for the arm being pushed in - it’s likely to do with some dodgy weighting or an issue with the exported base pose.
