Hi,
Support for UE5.4 was added in 20.0.689, so can't be retroactively added to a previous build.
See the
changelogs [
www.sidefx.com]
If you download any daily 20 build - you'll get the 5.4 plugin.
We purposefully removed the 5.4 plugin from the production build - Epic broke a ton of things with 5.4 - and we didn't want to ship a production build with an untested version of the plugin.
@isaac There won't be any new 19.5 production build - once a new version of Houdini is released, we generally stop doing production builds soon after (though we generally try to do a couple extra ones - but rarely more).
