I'm kinda new to UV unwrapping so I'd like to have your help here.
So, I unwrapped all my individual pieces, collapsed all the pieces together and applied an UVW unwrap modifier to the collapsed object. Selected all the UV islands, rescaled them, and when I go and use the Pack: Custom button, for some odd reason it doesnt spread the UVs on the little square, it kind of alligns them on the bottom and last side, leaving A LOT of unused space in the middle, right and up areas.
I've done it before where it packed everything perfectly, I just can't figure out what I did wrong this time for this to be happening.
Thank you in advance
