Protonic+ is a merge of various merged checkpoints that depict scenes of nature and backgrounds (in general) in a very stylistic and pretty way. It's primarily anime-ish with a somewhat 3D style. I merged several checkpoints then merged my merged checkpoints with the same initial merged checkpoints and then with my previously merged checkpoints until I was happy with the result (it's basically a salad of merges).

So basically, this checkpoint is good with scenery & backgrounds, but it is also capable of generating characters, both in SFW and NSFW contexts BUT I don't recommend it - If you wanna create erotica, you're better off using a Pony or SDXL model...

For negative prompting I highly recommend the use of negative embeddings such as FastNegativeV2 or badhandv4 especially if you intend on generating characters.

It's really no different to other SD1.5 checkpoints in terms of what sampling methods and positive prompts to use.

• Euler A: 30 steps

• DPM++ 2M SDE Karras: >=40 steps.

• Other samplers: I dunno!

• CFG scale: 4-9 for best results

• Resolution: Great results at 450 x 800 (with high res fix to 2, so 900 x 1600)

• Recommended to use with high res fix enabled and clip skip 2 for optimal results.

How I made my images:

(example)

• Prompt: Cyberpunk city, alley, people, neon lights, cinematic

• Negative Prompt: FastNegativeV2 or whatever other negative embeddings you like

Protons are cool.
