It happens when I select extreme values of skin tone in Metahuman Creator. Attached a few examples of textures with green, blue and red spots only happening in the body textures for all 4 extreme values of Skin Tone (combinations of U, V) as shown below, male and female. Those are files downloaded from Bridge. Below the video links for review:
I’d appreciate if someone can point me a workaround.
Thank you.
i got same problem , is this problem had been resolved?
hope some one reply any ideas to solve this issue . 
thanks.
after few hours i doing this , for now the only way is adjust the skin color U&V to Dark color and loss of rosy ,can remove the red/green/blue spot from skin textures.
we need to use photoShop turn the color back as what we need,this waste time . 
I was excited with the latest update of the Metahuman Creator, however, the issue still continues for darker and pale skins. I contacted Quixel, they told me only Epic’s team can fix that.
Hopefully this issue is going to be fixed soon in the next updates.
Best regards,
facing the same issue with MH 0.5
