So, I figured out my issue with Sketchfab, apparently I managed to save the view from VR somehow, creating the super off center Model-Nav. Man, the past few days have been terribly-awesome. I am feeling the “burn” from putting in “work at the gym.” Had to work through the issues of getting texture sets to import into substance painter which starts with some changes in Zbrush. And had to fix exporting them all as separate objects/uv maps from from Substance into sketchfab, (ctrl+J in Blender was the hot-fix) and think about how to correct the UV map issues I ran into in the future. For whatever reason, even after changing the names of the sets, it was still somehow associating old-names with files. Not sure I am through the woods on that yet but, all in all, feeling good. Was able to work through the problems I was having and generate my final submission for this thread.
It’s only the base materials for the textures sets or body parts. Nothing detailed, no real effects other than some smudging and scratches. Hope to give the eyes a marbled/glass like quality … and some pupils! I’m okay with this though, and will post a polished result somewhere many moons from now.
