Thanks for the info although it confirms that VR Tools might not be ready for primetime. That's my guess too. But without some way of calculating, do we know if 32GB is enough? And if SLI will get you there or does it have to be a single card? The lack of info on this is disconcerting. -----Original Message----- From: After Effects Mail List <AE-List@media-motion.tv> Sent: Thursday, June 21, 2018 1:31 PM To: After Effects Mail List <AE-List@media-motion.tv> Subject: Re: [AE] VR Tools GPU/CPU VRAM limitations On Jun 21, 2018, at 9:19 AM, Stephen van Vuuren wrote: > I can find no useful information on: > > * Is there a way to force CPU rendering? > * How much VRAM is required and can you use SLI to split via multiple cards as 8+ GB VRAM cards are very expensive. > * What frame sizes does the VR tools support? We have 5600 x 4200 and 8000 x 8000 - the weird part is simple projects are fine, but bring in lots of layers, bitmaps and the errors begin. > The VR tools are GPU-only, and this has been a huge problem for us. Due to the nature of VR, the resolutions are often very big. We were rendering 8000x4000. We working working at quarter rez or smaller, happily rendering at half-rez to see our revisions. Big mistake. When it came time to render full-resoltion, most of our machines were incapable. Among our 30 Macs we had just 4 that could do it. Weirdly, we had other machines with the same graphics card and everything else that couldn't. I guess we were lucky to have the 4, or else we couldn't have rendered. I'd guess having as much memory on the Graphics card as possible would improve your chances of being able to render, but this business of not falling back to the CPU is untenable.
