Oh, and if anyone was wondering why the leg bone in the Sketchfab has stickers on it, I was trying to add points of interest for PhotoScan to match to. The only one that it keyed in on very well was the star sticker. These of course won’t be in the final product 
I’m currently working on the skull again, this time taking the shots in the light tent, on the turntable. The only problem is I have to mask every single texture. With the leg bone, this wasn’t bad because it fit entirely within the borders of the turntable, which was black. This offered enough contrast that the quick select mask took in Photoshop did a pretty good job most of the time. But the skull is big, and a lot of time the backdrop behind it is the light tent itself (which is white), so the contrast is not so good. This makes masking a PAAAAAIN. In the future, I’ll probably be changing the backdrop to a more contrasting color. Or green screen.
