I noticed we don't sort the image files correctly (1, 10, 11, ..., 18, 2, 3, ...). We've fixed that up in 4.0.42-beta!
Seeing you clear all those mesh paths one-by-one makes me sad, so we've added that in 4.0.42-beta also, for both meshes and regions. :fiesta:
A tip that could help a tiny bit: at 9:55 you need a bone at the tip of another bone. An easy way to do that is to select the parent bone, then in the tree properties choose New...
Bone. If you have the axes set to parent or local, your new bone will be exactly at the tip. If you have the axes set to world, your new bone will appear at the 0,0 world position.
I guess you don't actually need the 6 bones for the "spokes". You could use them to position the rock bones, then move the rock bones up a level and delete the spoke bones.
At 14:22 you could turn off the tree "scroll to selected" button, so it won't scroll when you click each bone, then you don't have to scroll back down to the images. Maybe not worth it for the 6 rock images, but I think a lot of people forget about it completely. In a larger project the scrolling can be pretty far.
"that looks terrible guys" hahaha! π It shows how to do it well though and it's obvious it could look better pretty easily. π Another great video!
