Is it possible to generate assets on the fly? Are all assets and configurations parsed only at launch, or can this be refreshed automatically mid-game? Are there library functions available that can write files to the assets (or mods) directory structure? If not, then how do the custom signs work? Are there library functions that can call other applications or scripts sitting in the game directory structure? (I realize this would be extraordinarily insecure, but it would certainly not be without its uses.) If it is strictly impossible to build completely new assets mid- or in-game, then knowing now will allow me to put my focus on developing tools that will allow for quicker mod asset generation, rather than a single mod in-game asset generation engine. Thanks, y'all.
