Lora trained off of a bunch of thermal images.

Main tag: th3rm4l

Helpful tags: glowing eyes, orange glow, orange eyes, purple hair, purple background

To get 'proper' thermal images you can specify the 'correct' colors for things by their temperature (from cold to hot its black ->purple -> pink -> orange -> white), you can also set the weight to above 1.2, but it does give a nice effect at lower weights (example in the images).

As this is basically just colors the images the more color tags you add (e.g. blonde hair) the less this will have an effect.

How I use it:

Tool: Forge

Checkpoint: Midnight v20 baked vae

Steps: 20

CFG Scale: 1.3-2

Size: 940x1216 (or something similar)

I then img2img at 0.4 denoising strength, with the largest size to 2048, and the Lora's strength down to around 0.5.

Then ADetailer the bejesus out of it (specifically with mask dilation around 40-60, inpainting mask blur around 30-50, and denoising around 0.3-0.6).
