advanced rendering for AutoCAD
How much does it cost to use cloud rendering?
I pulled the option to use my Azure Batch cloud out of the current product. There wasn't much interest in it. You can set up your own Azure account with Microsoft and use it, it's not trivial but also not too hard. I would also be willing to give you access to my account so you could experiment.
I think the most expensive machine I've got listed is a code f8 -- a fast 8 processor machine which rents for about $.40 / hour.
Here's a link to some Azure Batch pricing.
