Presently, one can push sims through Reallusion, in a roundabout way, and then to Unreal Engine. Either of the latter two have connectors for Omniverse. The sheer amount of render power required for such thing, really could use that. I'm on a 32 core threadripper with an RTX 3090 with 24 GB of VRAM and 256 GB of RAM, and a 1080x1920p clip of just the clothes and a simple, single-color avatar, took 40 minutes, and nearly see the CPU on FIRE!
