Hi @BoneLady
Great job Pamela , not easy , it is all about the right angle , difficult areas produces shadows preventing the infrared to enter the areas .
If you want to keep textures , you need to keep pause the scans and change the angles , if you don’t need textures you can scan individual angles and merge them together by cutting off mist the areas that are captured already leaving around 20% overlapping.
Another thing you can do is convert the RGB color per vertex data into textures after merging so you still keep the color data but that would require some experiences with other 3D editing software like Zbrush, Blender or other …
Try to evaluate your bones to find the perfect angle entire , you can try it with simple mini flash light to see what angle produce less shadows … since each part is unique and complex you have to evaluate it each time as there are no shortcuts.
