Looking at them now, I realize I never made them cross-compatible between Studio/Part Designer and LDraw—and indeed, the sticker (or patterned) parts I have created don't appear in LDCad. So I've got more of that process to look into; perhaps then I'll realize why most modelers avoid it. :-)
Far as I know studio uses it's own texture mapping extension on top of the LDraw part geometry.
So any textures will be lost when 'exporting' to LDraw.
