This was made as a bounty submission, and came out pretty well. The LoRA can do both solo and couples using different trigger words. Also the LoRA should be pretty compatible with different styles and models.

Make sure that you use the trigger words as given below for the situation you want to prompt. Also, I'd advise looking at the prompts for the showcase images in the model page. It can be a bit hard to prompt for the exact claustrophobic situation you want.

Trigger Words (essential):

Solo:

cl@ustr0ph0b1ccr@mp1ng, trapped, enclosed, cramped

Couple:

cl@ustr0ph0b1ccr@mp1ng, trapped together, enclosed, cramped

Sometimes, "full body" may need to be included with in the prompt. Refer to the showcase image prompts for more detail.

If you are using A1111/Forge, and the LoRA does not show up as SDXL, you can force it to appear by enabling the "Always show all networks on the Lora page" option on the settings page.

Most resolutions should work well. Feel free to discuss problems and doubts in the comments.

If you want to support more models like this, or you just like what you see: ko-fi (｡♥‿♥｡)

Do tell me if the early access bothers anyone, and I'll surely remove it.
