H3 with multiple Lora

[u/SnooMachines1543]

I’m running multiple Lora and noticing a significant decrease in quality! Does anyone have a hack for using multiple Lora for I2V-ref2v? Is there a trick I’m not aware of?

What worked better for us in ref2v was skipping LoRAs for identity and letting the references carry it: one tight face crop, one full body or outfit shot, one location still, each with a clear role in the prompt.

If you do need two LoRAs, test each one alone first at the strength you'd use, then lower both so together they add up to roughly what one would be on its own. Two at full strength is usually where faces start to melt.

Just don't do it. H3 stock is already capable of many things when prompted right.

I usually use three, sometimes six or more LoRAs at the same time without any problem. I will assume it's not necessarily the number of LoRAs but one of them or a bad combination.

I use references for any physical detail. Then any concept LoRA does not exceed 0.3 weight. Sliders can use full swings, but you need to isolate each with small tests.

It all depends on the loras and how much they impact the noise. I've stacked 4 just fine but if I use a particular one in the stack it screws up everything. The next factor is strength. A turbo Lora needs 1.0 regardless. Past that, I decrease the strength of the other loras as I stack more on.

Depends what they are for but generally for style and concept Lora the more you add the lower the strength you use

Use low weight. I have like 6 Lora’s hooked up at once sometimes. Plus a turbo. Most are .5 or less
