Block explanation?

[MrReclusive]

Is there any detailed info on blocks?
I've been working with lora's, specifically 2 character lora's I trained.
By themselves they work great
but as soon as I used them together it became a mess, looked like a video that was compressed 300 times.
after some experimenting with block editor, i figured out removing all single blocks helped, removed all weirdness from stacking lora's

so I continued to play with that.
with the male character on double blocks 0 through 9, he looked nothing how he was supposed to.
but the female character on double blocks 10 through 19, still looked exactly like her.

so it seems to me, specific blocks are doing specific things, anyone figured out what yet?
i assume certain ones control motion, certain control style, certain control looks of people, etc.
just curious if anyone has dug into that yet?
