Nice to hear you again. You´re using DXTBMP?,then you go to prefs menu and set PSP as your favor editor. If you load the texture you want to edit with DXTBMP and doubleclick on that texture then PSP will be opened and loads the texture over the windowsclipboard.. before you close PSP you may set in DXTBMP “reload before close editor” then the edited texture will appair in DXDBMP.
I hope that helps you to retxture your rolling stuff.
