Note: as you increase the parameter numbers (quality settings) it causes more work for the cpu and memory, so a 1 to 3 min model generation on default settings with boosted settings for highest quality it can take 5 to 10 mins per model. 

Batch mode: Dont work on a single model at a time to use . Use your time effiecently by workin working on multiple images and models to get the best quality and a batch workflow going. While the GPU is busy in batch mode generatig the 20 models you can could be editing the 2d images into parts or doing other needed work like inspecting model gen results, upscaling or cutting out heads as higher res parts, inspecting the many model generated already to select the best one, creating walkmeshes and other housekeeping tasks

Its best to use higher settings and submit multiple times the same image so you can try different output quality to find the best models generatable. (basically By not waiting for the current run to finish you just submiting again with multiple either a new image or different parameters and it queues up and runs automatically and you can do many images/models in a batch run at the same time).. When you queue it may group the generated models and so do stages with multiple models to make generation more effiecent. You can monitor the batch run via the log or on the top left there is a batch queue toggle button to show the queue and results. You can right click and choose load workflow on the preview image it will load the workflow with image and settings from a previous submission. 

ComfyUI queue sumbission makes it very So its efficient to try multiple settings (recommeded to get the best results) with long generation time (5 to 10 mins per model) as Comfyui batch mode runs in the background to convert to models. It runs in the background for an hour or two can run for hours and then you can inspect results and can decide what you want to do with the models or resubmit with new settings in another batch run. Or While your GPU and pc is busy you can do the work of 2d image management or do light blender use work to inspect the models but you cant really use your gpu as much as its busy at 100% use most of the time.do gpu heavy tasks while its doing batch mode.

Workflow node properties tuneable:

Num Faces – Controls polygon count
Octree Rendering – Helps with structure refinement
Steps Count – Affects model detail level (aim for 50 to 100)
Guidance scale – Affects how much the 2d image will be used exactly to generate model/texture or how much freedom AI can get to make up its own design. able to set between 0 and 10. 0.75 default which means 75% follow the image. Higher values tend to produce better looking models. lower values result is more like playdo mess. It works fine at 9.5 or 9.8 if you want to follow the image exactly. 
Texture Size – Defines texture resolution
Delight Settings – Adjusts texture lighting and color balance. Can make a big difference so worth adjusting per starter image. default 0.75 try range between 0.50 to 0.90 for whats works for your image brighness.  
Upscaler 4x – Improves texture quality (OFF by default; should be turned ON). A 6x better quality ai upscaler extra plugin is recommended.
