Bright it would be the same as switching the standard RP, honestly the server needs this to spice up the gun skin's cus honestly there not that cool and WAY to rare for ppl to actually "search" for them.
Its not that easy to just switch the rp. Making a whole new rp from scratch could take months or even longer.
But you dont need to make a whole new one, just replace the outer layer of the model with the patern and colors you want and save it, then apply. I could be wrong, but this makes sense to me.
