My advice (for both version) you shouldn't only use this lora to achieve desired output, this will get you on the track, on this particular position at least but not always all the way there. It is probably already what you guys do, but just to be sure, it's not a solid enough trained lora on its own to make the 'perfect' video each time. I tend to use 0.75 to 1 strenght on the high model, and anywhere from 0.6 to 0.9 (rarely 1) on low model, but this is very trial and error, and depend on how many other lora you have, sometimes you'll need less sometimes a bit more...

V1.2 is a small upgrade, most of the time it will be better (enough that I don't use the previous model anymore) but it is probably not as stable, a touch more hit and miss (but when it hit it's better) trained using higher resolution, and two more video in the dataset, and slightly revised caption, possibly still undertrained... or over trained, no ideas, but clearly not the most optimal it could be.

example prompt : A beautiful woman is lying on top of a man, her legs are spread, the man is holding her legs up as he fuck her in the ass, reverse anal cowgirl position

It does reverse anal cowgirl (Yes, not very original I know) PROS : Quite good at one position in front view, CONS: Quite stubborn (because the one position and one view proficiency, meaning too rigid) also have strong tendency to create almost flat chested small breasts woman body type (mostly because training date hadn't enough big boobs, this will be 'corrected' in V2 if V2 ever exist one day) which tend to create too young looking women for my taste (but this can be somewhat corrected by using macromastia and other character lora so not an impasse, even if it's a weakness.

Trained on windows 10 with my crippled undervolted vastly underclocked and under powered RTX 3090 and 32 GB ram (if DDR4 ram wasn't so expensive i'll immeditatly go for 64 or 128...), no deepspeed, no sageattention, nothing just barebone (but it work, a bit slow but it work so...) using the very easy to install/use Musubi+GUI by https://github.com/PGCRT/musubi-tuner_Wan2.2_GUI

This model is probably under-trained, (trained only 8 or so hours in total for High and Low train, I suspect I needed at least 10 more epoch (so about 2-4 hours more) only 7 clip used of about 3-4 seconds each, still I would say in my test at least 4 out of 5 video are of good quality (no major missing part) and probably closer to 5 out of 5 if you add some other NSFW loras to fine tune, also maybe more steps (5 in my tests, with 6-8 it should already be more stable) I used rank 32 alpha 16 in the training (default on the GUI was 32/8... Not sure if it's better, maybe it's not, not really sure how 8 to 16 change anything to be honest, not enough experience training wan2.2 loras
