Hi Billabong, I think it has something to do with this area here:



If I separate out that piece then it gets a consistent orientation for everything else.

I'm still narrowing it down to try and find what is going wrong in that spot.

Hi Michael, how do you manage to isolate the problematic area ? was it just a guess ?

Hi PaQ, I tried testing some isolated chunks of the model and saw that they were making consistent normals ok and with repeated testing narrowed it down to that area.

Now I'll see if I can narrow it down further yet, there is probably a damaged trim boundary in there somewhere.

It appears to be these 2 faces here, if these are removed the orientation is ok:

There's an edge in there that's squashed down to to a point.

Hi Billabong, please try with this attached version. I removed the squashed edges (using untrim) that were on those 2 faces.

Hey Michael,

Sorry for the late reply. Thank you so much for fixing this. If you have a min. can you explain in some more detail on how you found the error? Did you just export out sections and bring that into 3D package to see if the problem?

@ PaQ,
Thank you for trying as well. It so much appreciated.

Hi Billabong,

re:

Yes I broke it up into chunks and noticed that some pieces were exporting unified normals ok. So I took those pieces and gradually made them larger.

Understood. Thank you again
