Howdy fellas! I have a question.

I'm trying to render a scene with 5 characters in bar. Buut... I just can't. I have pretty decent GPU RTX 2070 Super. But every single time when I'm trying to make some renders DAZ just crashes. Any ideas how to fix this?

Characters are G8, render with Iray.
My PC does the same thing sometimes. I always check the shaders and make sure they are all Iray Uber for the shader.
I have 2 gtx 1660 gpus.

Maybe try rendering the scene in sections? If there is little light interaction (like shadows) between the background props and the characters - render the background separately first?
Or maybe render the characters separately (with transparent backgrounds) and then overlay the files in a program like Photoshop or something similar?

tk99 Boogie I'll try I have 12GB RAM but I'll try Optimizer. Thank you ;)
If the render uses more VRAM than what's available in GPU, Iray will drop to CPU and if there is not enough DRAM and no pagefile, the render won't proceed. These are just my very, very rough guesstimates of how memory is used in Daz:

memory for render = total - 2GB (assuming the GPU is also used for OS and mutltitask) so you have 6GB VRAM
G8 character @ subD2 = 1.5-1.8 GB each without scene optimization subD4, i.e. HD characters use multiple times that each.

2070 has 8GB VRAM but only 6GB can be used for render. You have 5 characters so that's at least 8GB and probably more than 10GB with the other stuff, which is why the render won't go through even when it drops to CPU and looking to fit the scene into system memory (12GB - 2GB = 10GB).

Daz3D memory management is a blackbox, a terrible, terrible blackbox.

The aim for my new rig is to have 64 GB of DRAM on top of the two GPUs I want to add - just for the reason that DRAM is used when VRAM is used up. Also use a SSD for pagefile.

I read once that the max amount of Ram you ever need when rendering with Daz3d was 16GBs whats more important is the video card. The more powerful the Video card, the faster the render. But I could be wrong. Its a topic I'm always intrested in learning more about.
