Hello Alex,
Thanks for your interest in Qube!
Our software does work with the 3dsmax/v-ray combination.
You just need to "Assign" the v-ray renderer as you would normally do in the "Render" dialog,
save your file, and submit to Qube!
This of course assumes that 3dsmax/v-ray are set up to run properly on the farm machines--
there is not a version of 3dsmax that runs on Linux, or any render management system
out there that render 3dsmax jobs (or v-ray) on Linux.
