Yeah I have no problem having only 1 instance running at a time, but in the past you could fire off 3 renders and not attend to the machine again until they're all done (because multiple requests rendered in parallel). That functionality has been lost - now you have to manually render each pass sequentially. It would be a huge improvement, back to previous efficiency, if multiple render requests could organize themselves to render sequentially so that I could leave the PC and have lunch for example, and not hang around checking every few minutes and firing off the next render.

Amazing.. so realistic.

It sounds like you need to install a later version of Houdini as the license server (hkey) is bundled with Houdini…
