Bunch of black strips in PTEX auto Ambient Occlusion.

[BillyGoat]

I need some help with a PTEX Ambient Occlusion issue i'm getting. 

I have baked out the Auto Amboc on an imported 3ds max OBJ mesh via the PTEX "Paint" window. I successfully baked out one a bunch of times previously with no issue.
But just recently is has seemed to always finished the amboc on a PTEX model with black and white strips. 

Images of this can be found below. I have changed the texture size to 4k and 8k, with varying mesh density both above and below the resolution i set with the same results. I have also tried the standard 64 bit 3dcoat without CUDA support. 

Has anyone had this issue before? and is it something really simple that I've started doing wrong? 

I am running  4.5.19 3D-COAT DX64 (CUDA).

On the below spec machine.   

OS:              64 bit Windows 7 Proff service pack 1. 
Processor:   Intel i7 5820k CPU @ 3.30GHz
RAM:           32GB
GPU:           NVIDIA GEfORCE GTX 970 

All with latest updates. 

It would be amazing if someone could get back to me on this as soon as possible. If i need to post up any more information or screenshots let me know. 

Thanks in advance. 

Billy.

A more severe case of the issue.

I have simply gone back into the source mesh and re-exported it out as the same mesh type (OBJ) and everything now seems to work now. So i guess this turned out to be some sort of corrupted mesh and not any issue with 3d-Coat. 

Feel free to move this out of the Urgent thread. 

Cheers, Billy.
