DPropertySheet - Possible to use custom silkicons?

I’ve noticed a severe lack of Silkicons in Gmod, so I converted a few of mine to vtf format, and they work (in game, with other methods). However, when I try using them with DPropertySheet, they give the missing texture image (ie black / purple checkerboard). Can anyone clear up if you can use custom silk icons on DPropertySheet or not?

You also need a vmt, use the silkicon packs floating around on gmod.org.

Yeah, I just realised the VMT I made was pointing to the wrong area, Thanks though.
