SSS rendering Black

I have a skin material that WAS working just fine for me. Now, for no reason that I can figure out, whenever I render, it comes out black! The sphere in the material editor is rendering just fine. The objects that I have the material applied to were X-Refs but I merged them in to see if that would solve the problem.

Anyone have any ideas? I’ve wasted two hours on this.

do you have refractive caustics checked in the indirect illumination panel?

I’m sorry, I should have specified that it’s the Fast SSS material I’m using.

Try changing the radius values and see if it helps. Also, just for a test, apply a new fastsss material and see if it works.

Best regards,

fog color of 255?

I found the problem. Somehow both the Shallow Radius and the Shallow Color got set to 0. I have no clue how that happened.
