HtoA Loading AWS SpotFleet Linux Instance

Hello,

I’ve been able to launch Houdini Jobs via an AWS custom instance(via Deadline) and am attempting to render an HtoA job within Houdini.
I’m having trouble getting Houdini to load Arnold using the Houdini.env on our instance.

Somedetails:

/home/ec2-user/houdin17.5/houdini.env
reads as below:
HOUDINI_PATH=/home/ec2-user/htoa-4.1.1_rf2c4e45_houdini-17.5.293;&

My htoa install path is here:
/home/ec2-user/htoa-4.1.1_rf2c4e45_houdini-17.5.293

However doesn’t seem like it’s getting loaded when the deadline slave launches on the spotfleet instance:

I guess I would start with hconfig -a

And strace to see if HtoA is even found during startup

Hi Stephen,

Thanks!

strace hconfig -a showed the following

......

write(1, "HOUDINI_PACKAGE_VERBOSE := 0\n", 29HOUDINI_PACKAGE_VERBOSE := 0 ) = 29 write(1, "HOUDINI_PATH := '/home/ec2-user/"..., 72HOUDINI_PATH := '/home/ec2-user/htoa-4.1.1_rf2c4e45_houdini-17.5.293:&' ) = 72

........

Is there supposed to be any other HtoA related var that I should check?

Thanks,

-Jake

Hi Stephen,

I moved the houdini install to the "opt" directory and it worked. I'm guessing it was some sort of permissions thing.

Thanks,
