V2:
V2 is V1 merged with my Blush/Red Face Slider in negative value, and adjusted a bit on the strength to match V1.
On the V2 sample image with 4.0 in strength i used 5.0 on the refiner pass. I found that about 20% higher value on second pass give the best results.
V1:
Applies to whole body, but mainly chest, neck and face. Work in both directions, so it can be used in combination with my face blush LoRA to get different ratios on face/body.
