Bug Fixes
-
HTOA-2517 - Added a warning if the HtoA HDK API version doesn't match the Houdini API HDK version For example, i you use HtoA for Houdini 20.5.370 with Houdini 20.5.410, this warning would be printed because the HDK API was changed:
- An HtoA release for an older HDK version may still work in newer Houdini production builds.
- If a warning isn't printed, then that means HtoA is binary compatible with your Houdini version and you shouldn't need to worry about crashes or instability.
- There will still be a HtoA build when a new Houdini production build is available. This is just a plugin stability sanity check if you need to use an older HtoA build in the newer Houdini while you wait for a new HtoA release.
- HTOA-2762 - Cryptomatte metadata is now saved correctly when using the raster product type in Houdini 20.5.410 or newer. Note: In Houdini 20, you must currently use the latest daily build to take advantage of this fix.
