The camos aren’t working on some armor/clothing. Did I install the mod wrong?

No. It’s a well-known issue that we are slowly working on fixing, but it is a painstakingly slow and tedious process.

Limb Armor (Arms and Legs) camos showing as missing/pink/purple textures is an issue within the mod itself. Not user error. Only the base colors work for the Limb Armors currently.

DTO Vest, all 3 Holsters, and the BDU camos should work fine though with the exception of the DTO Vest CADPAT Arid not working.
