Does anyone use this software to update old assets ?

Trainz Content Utilities - 1.0.1

I've used it for new assets although the naming of the mesh files is a pain. For repairing older assets I use AssetX although its becoming out of date for TANE and TS19 although still usable.

I'm toying with the idea of making my own tool.
