>>780 (OP)
HunyuanWorld1.0, a new 3d-world generating model, seems great, but I was unable to make it run on a 4090 and 64 gigs of ram, seems you need about 100 or so, even with my script editing to make it more efficient.
The part it can't handle is the generation, the Panorama and world masks were surprisingly not very intensive, I could not run it originally either, but switching the model to use SDXL over FLUX, made it take shockingly little compute resources, could probably run on a 12gb model.
The actual mesh generation itself is poorly optimized by the gooks and has a ton of RAM eating processes running in parallel instead of sequentially, I don't have the time and it is not worth it for me to fix such a huge flaw.
The panorama however can be used with Hunyuan3D Mesh Gen model locally to create the worlds however, but it's more intensive process obviously, good for HDRI generation though.
Hunyuan3d2.1 is amazing but the topology is mid, only real downside, the mesh generation takes little resources, texturing is more, but I could "max" out all settings on texture gen with my system, just high requirements for the model itself to load, after that increasing settings is gentle on compute.
OneTrainer is the best LoRA trainer I am aware of, works well, Hydrus for image tagging, the documentation for Hydrus is pretty bad, and UI is horrendous, but working with it is really smooth and great.
