The Houdini Engine for Maya plugin could not be initialized March 20, 2024, 2:24 p.m.

Hi, thank you for your reply!

I used the launcher to install everything, Houdini 19.5.493 itself and also the plugin. I noticed that it first checks the $HFS variable in the code so I manually added the path to environment variable and it is able to load the plugin now. So somehow the paths I put in the houdini engine preference are not recogonized.

Hello could you be more specific how to modify this??

It's been a while, but since I just ran into the same issue, I thought I'd answer for the benefit of those who come later. You need to edit the file maya.env, which is described here: []

Mine was completely empty, so I just added the line, as described by Bobcat:
HFS = D:\Production\SideFX\Houdini 20.0.625

That's obviously the path to my Houdini install—you'd change it to wherever yours is. Once I'd made that change, Maya loaded the plug-in without complaint.

Ah, I see. I should probably defer to the folks who understand USD at a lower level than I do. Although responses may be slow this week due to an event in London.

There's not really any such thing as a best place. Put it wherever makes sense for your workflow. Personally, I like to segregate USD from the rest of Houdini's geo, so I stick it in $HIP/usd/…
