Been working on supporting weapon camos and charms to directly support Gunsmith.
It may be a while before this is implemented as we're still proving the workflow, and only the M4A1 has skin options. Here is an example of what it could look like.
We're also working on weapon charms. These attach to the side of a gun and move in line with the weapons movements. Again, early stages but fun to see.These cosmetics will be unlocked through using the weapon or through achievements.
