So... is there any easy way to get a good quality png out of an in game weapon? I'd like to look into extracting several of those pinwheels and then using them for a Day of the Dead. And because the pinwheels would be a single shot graphic, the system load would be a fraction of what it is now. I guess I could write code to translate the weapon patterns into a graphic, but that's would be effectively rebuilding a portion of the game engine, which seems redundant.
Hmm, not an easy way. But if you set up a new tileset where everything is black/transparent, then set up a test chamber to use that tileset, you can probably get a room that has nothing rendering in the background. Then spawn whatever shots and take a screenshot (those are saved as .png, right?) and cut up as desired.
