Human skin texture issue

[bondobrus]

Scail 2 is the best open source model for character animation I've ever used, besides amazing character animation the model has one big problem - human skin looks too smooth. I'm not sure if that's a wan architecture limitation so I decided to ask: does training a character lora on wan 2.1 or using any lora help resolve the issue? Big thanks!

Hi, thanks for the feedback! Regarding the overly smooth skin, it is indeed a common trait of the base model. You may first check the reference frame: does your initial reference image already have very smooth skin? If not, increasing resolution or adding a close-up portrait with clear skin texture as an additional reference image (if possible, and you may need a multi-reference workflow of SCAIL-2) may help.

Regarding LoRAs, some texture-focused LoRA trained on Wan 2.1 (specifically targeting skin grain or photorealism) may work, though I'm not sure about their compatibility with SCAIL-2. A character LoRA may not work that well because our model refers to the reference image to maintain consistency, but I'm really curious about its effect.

Hope this helps! Let us know if you find a good workaround or a combination that works best for you.

Thank you. I already did the same reference image and video comparison vs Kling motion control, so same inputs for Scail 2 and Kling 3 motion control. I'm aware the model budget is not comparable, I don't expect the same quality as Kling, but I thought the difference wouldn't be that big. I'll try increasing width and height to match 2 megapixels instead of the current 1 megapixel and add a second reference.
