Houdini, unfortunately, has no native support for the PRT file format used by Krakatoa. There’s
an old plugin from Thinkbox that comes in as a Python module.
It compiles, but I never got it to actually do anything. If you get it to work, please let me know!
Luckily the good people from Robotika and Fiction released their own exporter for Houdini 12 some while back.
I forked this and modified it slightly to compile with HDK14 and VS.
These were compiled and tested with the Indie version on Windows 7. I’d assume they work with the full version and maybe Apprentice too, but I don’t know.
Here are the DLLs for a few builds. I’ll update this post if new versions come along. No warranty or anything of course. It’ll either work or it won’t…
