Hey guys,
What's the little hack to fool Deadline 10.4 to use H21+, Only supporting 20.45 off the shef. I'm trying to set that up on our side, but i'm not getting anywhere yet. If anyone could point the way or give me a complete breakdown to make that work i would really appreciate. I understand it's perhaps a question for AWS / Thinkbox but they not super responsive on that side.
Thanks in advance.
A.

I updated to 10.4 and H21 myself couple weeks back and it was pretty much the same as with 19 and 20. You need Deadline json to point to right place as as package and also submitter dir to both HOUDINI_PATH and HOUDINI_MENU_PATH. Then of course in that location you need to have deadline scripts and also python libs. It should look something like this:

, json attached too.

I'm still getting that error:
Unable to locate '
CallDeadlineCommand.py', please ensure your Deadline ROP installation is correct.
I edited the paths in the Deadline plug in config, i edited the json as well to point to the right place. (i think). But nothing does it yet.
Cheers,

Supposedly this should work. I have not tried yet with 21+ though.
