Hello,
When preparing artwork for rigging, where do you spend most of your repetitive setup time?
We are building anysplit to streamline this preparation phase, and we want to hear directly from modelers.
Which tool would save you more time?
Option A:
Recognizing fine boundaries like hair strands, clothing details, and accessories to split them into clean layers.
Option B:
Filling transparent areas and extending occluded areas behind overlapping parts for mesh.
Please reply with A or B in the comments below.
Thank you for your time and feedback!
