I'm curious. Will Houdini 5.5 Apprentice open files last saved in Houdini 3.2? I tried it without any luck. I set my HOUDINI4_COMPATIBILITY to 1 which opens my Houdini 4 files okay (albeit with many error reports) It seems that Houdini 5.5 doesn't load any geometry or textures at all from 3.2 .hip files. Does anyone know of a utility or something that can update old files. Cheers.
