I just remade the textures or... you can say ported them. I dunno if I should post them because of this post being the og one ssoooooooo.... I'll just tell the method :). [+this ain't a noob friendly tutorial]
Step 1: Go to (BO1 folder)\main\iw_13.iwd\images\ and extract ' ~~-gmtl_t5_weapon_m1911_mp_s-~bffff598.iwi ' and ' ~~-gmtl_t5_weapon_m1911_s-rgb~a819b527.iwi '
Step 2: Extract the .iwi files using texture toolkit and resize the images from 128x128/256x256 to 512x512 pixel resolution. Not doing this can cause the textures to not load.
Step 3: Rename the ' ~~-gmtl_t5_weapon_m1911_mp_s-~bffff598.dds ' to ' ~~-gmtl_t6_wpn_pistol_m1911_s~5546ff61.dds ' and ' ~~-gmtl_t5_weapon_m1911_s-rgb~a819b527.dds ' to ' ~-gmtl_t6_wpn_pistol_m1911_col.dds '
Step 4: Use the texture toolkit to convert the renamed files from .dds format to .iwi and place them into Plutonium\storage\t6\images . Now you should be good to go...
