This is a DoRA, not your typically made LoRA. A1111 v1.9.0 and up is required to use this. Forge users must download two files, which can be found here. Go to stable-diffusion-webui\ldm_patched\modules and replace the files there.
Weight: 1.0
Backrooms: backrooms, realistic, no humans, indoors, ceiling light
Poolrooms: poolrooms, 3d, no humans, indoors, scenery, water, tile floor, tile wall
Liminal Spaces: liminalspace, realistic, no humans
An experimental DoRA that tries to recreate liminal spaces. Adjust prompt accordingly and see samples. The sources of the images include Google Images, The Backrooms Wiki, Kane Pixels' The Backrooms series, POOLS, and The Complex: Expedition. I'm not completely satisfied, but it's serviceable enough.
The results of your generations are dependent on the additional LoRAs, weights, and models you use, so it may not work or come out as consistent as my sample images.
