DAZ doesn't use my GPU to render with Iray

[MissFortune]

No, it prevents Daz from always using the CPU (alongside the GPU), it will still fall back, even when unchecked, if the GPU runs out of vram

Hmm. That's never happened to me. Every time I've went over the VRAM limit (10GB in my case) I just get black screen on render, and I tend to keep a close eye on my CPU temps/usage while rendering (as my AIO's been finnicky lately.). There's not a whole lot saying it's being used (20% usage, with Daz and any combination of Edge/Spotify/Discord/etc. (Also forgot to menion earlier that I also have 'allow CPU fallback' unchecked, as TheDevian, again, mentioned.)

If that's the case, though, I stand corrected. Wasn't aware.

In my experience, with it all unchecked, it will just not render.

Ah, yes, I didn't see that mentioned, I thought you were only talking about the upper checkboxes, not the lower three. Of course, if fallback is disabled, it won't fall back

Yeah, that was my bad.

I do have scene optimizer, didn't use it though. I am doing some test renders for a VN I'm working on and just through some stuff together, without too much thought of optimization. I've been CPU rendering for quite a while and memory hasn't been an issue, though rendering this scene even with CPU rendering is probably pushing the boundary's a little.

I'm thinking I may split the render into parts, ie. render the figures, background and debris field separately. My thinking is that the GPU should spit them out quickly and it gives me more lighting flexibility.

Have you used instancing for the debris field? It will save vram.

No the debris field I'm using is actually a single asset, though if I do a little editing instancing could work great. Cheers!

That is probably my biggest complaint about daz vendors. The amount of time I spend chopping an asset up into usable pieces annoys the hell out of me.

I just want to open a kitchen cupboard, move the fridge or even open the french doors. Why make the whole thing one model? I try to stay away from the vendors that do it.

It took me a bit of time before I even realized you could edit geometry.
