I have an NVIDIA GeForce GPU, but it’s old and wimpy and this fancy new iRay render engine scorns it. Kicked me right back to CPU mode, jeering “Get your lame-ass GPU outta here!” 😛
I see the DAZ folk have at least pinned a forum topic with links to other multi-page topics to browse.
I have no patience for that right now, but I’ve downloaded a few PDFs to read. I’ll switch back to 3Delight until I get a better handle on this. (And it’s not like I’m all that interested in photorealism anyway.)
Though I have to say, that shadow catcher bit? Nice!
