Hi Scrubs-

I think I found an issue with SSS on the blender materials. It looks to me like the SSS radius is too large, especially evident when using lamps to light a scene vs HDRI. Here is an example:

The bricks on the left are not scaled nor have the materials been touched. The bricks on the right have all had their Scale reduced to 0.1, which reduces the SSS radius.

I think the most obvious pieces are the light grey ones, but you can also see it in the stud logos on the image below and definitely in the yellow-to-yellow transitions:
