[MDL ED] Regarding Custom Items

[Romulator]

I think for the sake of the game, as long as it is the same filetypes, it should work fine. If you can't make .tga formats with any current applications, I recommend using Paint.Net

Also - open up your broom in the Model Editor, and open up the User Defined Variables under the Settings up the top. Assuming you have your broom set to an "Item" (Type) and "Puzzle" (SubType), there is a little box which says ImageFile. Be sure to make that your broom image

And whatever the original size (IIRC, 60x60) is, the broom DOES NOT have to have the same size as a graphic, but will cause bugs otherwise if larger or smaller.
