Hello ! I am just a regular user without any knowledge of what’s going on under the hood, but I wanted to share something about Lora Block weight : I think I found the face layer.

Since this topic came up, I was thinking about this node pack and I wanted to run some tests. First, I checked the Lora was actually making the face correctly before testing. Then, I loaded the node and used the first presets. I generated one picture with these presets : DBL-ALL ; DB-FRONT-7 ; DBL MID-6 ; DBL-TAIL-6. I both used fixed seed and random seed in the block Lora weight and got the same results.

Here are the tests made with a Gigachad Lora but I tried others Loras with same results. I won’t put every pictures I made, but you can try by yourself and maybe discover other things :)

Without the last block, NO Gigachad

1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1 : Gigachad is here

About the single

Without DB but with ALL the single : Gigachad is back

I tried the other singles preset but I don’t get his face anymore, so this is the moment where I can’t explain what’s happening and I will need to do… more tests (removing one block at a time), will update when it will be done :)

So, what’s the point? It needs some more tests, but it could be interesting when you want to combine Loras (example a style and a character), or if the Lora was trained on specific clothes you don’t want to get (example : a dataset with only bikinis).

TLDR : use 1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1 on this node pack in comfyui and you will get the face trained on your Lora. Need more tests for the single part and I don’t know yet if it can be useful.

I think there is more to find with this, so if you try it and get something interesting, please share it here !

Thanks for reading
