How would i go about replacing a picture in a frame?

[DRedshot]

I'll try doing it myself, i'll see what I can do - I'll edit this message when i'm done.

Edit: It is either impossible, or too difficult to do without a 3d modelling program :/
If you have Maya I can write a quick tutorial for you.

All i'll say is, try opening the .dae file with notepad++, scrolling down to about line 60, and replacing the file path with your .dds's file path. (get the file path by opening it with notepad++, then at the tab rightclick>copy file path) make sure to replace "\" with "/"

Finally, try creating a .mat file and applying it to the entity in Notepad++

As I said, if you have a modelling program it's easy, so just reply and let me know
