Did a simple pocket pulling gimmick, could be fun for animation and posing! #b3d

That's actually cool!

Could you tell me if there are any techniques for evenly spacing the topology, or do you basically have to adjust each vertex one by one? I’ve been watching a lot of character head modeling videos recently.

EdgeFlow is great for spacing out loops/vertices evenly, I use it all the time!

Is that a separate plugin, or is it a feature within another plugin?

That's the name of the free addon, just make sure you download the version that matches your blender version for compatibility.

Thank you! I’ll keep following your work.

Make it two bones for fun, so it can stretch out less like an arch but more like a square/palm ;)
