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.
