Maybe I’m not understanding how a Total Conversion works. I’ve put an empty folder in the mods directory, cleared out the map name and selected cook total conversion. Ive made no changes to core files and its cooking over 197K shaders. At this rate it would be over a 2hr cook for a TC thats unedited. Is that normal? Cooking my mod, I never noticed it take this long or cook this much.
Edit: Reading is fundamental 
saw in the dev kit documentation that it will need to recompile shaders and that subsequent builds wont be as long as they will be cached. I guess updating to the latest dev kit cause shaders to recompile for anyone else wondering.
