There used to be a great guide/tutorial for Super Merger posted here to citivai. Unfortunately it seems to be gone now. I am posting parts of it here that I had copied. It was the parts I found to most important to understanding what effects different blocks have when merging models. It covered in general, what each block does. It is not the complete tutorial, but hopefully it is enough to be helpful to anyone trying to learn how to do merges. The parts I was able to find are posted below:
Output layers are more impactful for aesthetic.
Input layers are more impactful for composition.
Fine Details Layers: Minor, but important aesthetic polish. Sub surface scattering, shadow textures, eye lashes, nipple textures, etc
INPUT 00 -> OUTPUT 11
INPUT 01 -> OUTPUT 10
INPUT 02 -> OUTPUT 09
INPUT 03 -> OUTPUT 08
INPUT 04 -> OUTPUT 07
Major Details Layers: General Aesthetic and Flair, Photographic or Anime
INPUT 04 -> OUTPUT 07
INPUT 05 -> OUTPUT 06
INPUT 06 -> OUTPUT 05
INPUT 07 -> OUTPUT 04
INPUT 08 -> OUTPUT 03
INPUT 09 -> OUTPUT 02
Core Composition Layers: Pose, Outfit, Background, Base Elements of the Image
INPUT 10 -> OUTPUT 01
INPUT 11 -> OUTPUT 00
M00
GRAD_A: Blends Model B’s composition onto Model A’s image details, with healthy overlap.
FLAT_25: Model A absorbs 25% of Model B’s weight data. Mostly resembles Model A.
FLAT_75: Model A absorbs 75% of Model B’s weight data. Mostly resembles Model B.
WRAP08: Only Model A's fine details are overwritten by Model B's fine details. Composition remains A.
WRAP12: Modal A's major details are combined (not blended) with Model B's details. Composition remains A.
WRAP14: Model A's major image texture is combined (not blended) with Model B's image texture. Composition remains A.
WRAP16: Model A's core aesthetic is combined (not blended) with Model B's core aesthetic. Composition remains A.
MID12_50: Model A retains its fine and major details, but it absorbs 50% of Model B's composition.
OUT07: Model A retains its core composition but its fine and major details are overwritten by Model B.
OUT12: Model A retains its core composition but the entirety of its aesthetic is overwritten by Model B.
OUT12_5: Like OUT12, but Model A also absorbs 50% of Model B's composition.
RING08_SOFT: Model A retains its fine details and core composition but Model B's major details and some composition overwrite Model A's. Result is a composition unique to model A or B. Aesthetic is heavily combined (not blended) together, seems to lean towards Model B.
RING08_5: Very similar to RING08_SOFT. Higher influence of Model B.
RING10_5: Very similar to RING08_SOFT. Still higher influence of Model B.
RING10_3: Very similar to RING08_SOFT. Very high influence of Model B.
SMOOTHSTEP: Model A retains most of its composition, but has some blend with Model B. Nearly all of Model B's aesthetic is absorbed by Model A. Has mild blending.
REVERSE-SMOOTHSTEP: Model A retains most of its composition, and aesthetic, but its aesthetic is slightly influenced by Model B.
SMOOTHSTEP*2: Model A retains its aesthetic, but almost entirely absorbs Model B's composition. Has mild blending.
R_SMOOTHSTEP*2: Somewhat similar to RING08_SOFT, but the aesthetic is almost entirely Model B, but with more blending.
SMOOTHSTEP*3: Model A's composition is combined with parts of Model B's. Model A's major and fine details are overwritten by Model B.
R_SMOOTHSTEP*3: Model B's composition is combined with parts of Model A's. Model B's major and fine details are overwritten by Model A.
SMOOTHSTEP*4: Similar to RING08_SOFT, but the aesthetic is heavily blended. Leans towards Model B's aesthetic.
R_SMOOTHSTEP*4: Model A's composition is overwritten by Model B's. Model A retains a few of its core details. Most of the aesthetic is Model B.
SMOOTHSTEP/2: Very similar to GRAD A. Composition leans slightly more towards Model B.
R_SMOOTHSTEP/2: Very similar to GRAD V. Compositions leans slightly more towards Model A.
SMOOTHSTEP/3: Somewhat similar to RING08_SOFT. The unique composition is more exaggerated, and the aesthetic, while blended, leans more towards model A.
R_SMOOTHSTEP/3: Model A has big parts of its major details and composition combined with Model B. Model A retains its fine details. Aesthetic is leans Model B.
SMOOTHSTEP/4: Similar to RING08_SOFT. Aesthetic is heavily Model B with fine details from Model A.
R_SMOOTHSTEP/4: Model A's composition is overwritten by Model B. Model A retains its major details. Model A's fine details are overwritten by Model B.
COSINE: Model A's and Model B's composition are blended together favoring Model A. Aesthetic heavily favors Model A.
REVERSE_COSINE: Model A and Model B's composition are blended together, very slightly favoring Model B. Aesthetic heavily favors Model B.
TRUE_CUBIC_HERMITE: All of Model A and all of Model B are heavily blended together, slightly favoring Model B.
TRUE_REVERSE_CUBIC_HERMITE: All of Model A and all of Model B are heavily blended together, slightly favoring Model A.
FAKE_CUBIC_HERMITE: Nearly identical to TRUE_CUBIC_HERMITE. Very slight difference in fine details.
FAKE_REVERSE_CUBIC_HERMITE: Nearly identical to TRUE_REVERSE_CUBIC_HERMITE. Very slight difference in fine details.
If you want to see these in an XY Plot yourself, select mbw alpha for the X type (or Y type, etc), and drop this block, exactly like it is, into the Sequential Merge Parameters.
To run xyz with multiple prompts, use notepad to replace all commas with periods in the prompts, then once done, separate the prompts with one comma each so the xyz plot will accept them as separate prompts. (periods work the same as commas withing the prompts in Stable Diffusion)
