Tools for inspecting and manipulating asset bundles from Rogue Trader. Currently, it can export all of the asset bundles as text. End goal: produce a working Unity project export. It fully supports asset bundles from 2022.3.7f1 (all other tools fail on at least a few assets). Heavy emphasis on performance. The entire game imports and processes in under 15 seconds on my machine. Exporting all assets to disk takes 80~ seconds (50gb on disk).

Entry point for developers is at RogueTraderUnityToolkit/Main.cs. Pro tip: don't run it through your IDE if you care about perf. It disables optimizations and it takes a gazillion times longer.
