solly6WiethoofdI used the same path. It turns out I had "No fullbright" on the .vmt files which causes them to have missing textures/no textures at all but blank. The only problem is that it's stretched(and for some reason sniper's portrait is a crosshair)solly6materials/vgui/replay/thumbnails is the path where I placed the texture files. Still doesn't work.Did you also add VMTs for each VTF, fixing the path inside the VMT to the new path in the thumbnails folder?
And which path are you using in your .res file pointing to the thumnails, this should be something like "image" "../vgui/replay/thumbnails/scout"

You've probably got two VTFs with the same name in thumbnails, rename the sniper one to sniper_2 or something and it should work, also change the path in the vmt to sniper_2 as well. I don't know about the stretching, other than checking the original size of the VTFs.
