The new one is on the right, in the model you can see just a shinier color, but in the texture you notice that is more than that :*

First (Left)
Verts: 3.047
Tris: 5.457

Last (Right)
Verts: 2.023 (1.024 less)
Tris: 3.475 (1.982 less)

Sooooo… less is better? hell yeah!!! smaller filesize and faster loading, long live low end computers!!!

The main filesize was 18MB, now 11MB, buster arm is separated for animation purposes, each were 3mb (6mb for normal and shooting angle) now 1mb (2mb for both), so…13mb instead of 24mb, it may not sound great, but it makes a difference.

I guess i could have done it better, but is better than before so… maybe one last update in the future (Or maybe not e.e)
