Just tried a render in P9, and all was well, so I "upped" the render settings, enlarged the image, and I got these crazy spots on the output?  The only other reference where someone had similar I could find was here:  http://www.runtimedna.com/forum/showthread.php?65206-IDL-SSS-Render-artifacts

...but if I got to go through every material and start finding odd nodes...let's just say, it probably wont happen.  (lazy)

Anyone else see this or remember seeing it talked about?

I am re-rendering now, and it looks fine this time, and the only thing I changed was to turn off the Tone Mapping in the render settings (to "none", from previously "HSV Exponential")

Now looking at a lot of render setting examples...not too many have Tone mapping even set.  Is it a bad idea to use with IDL and SSS?

I think most render setting examples are probably with Gamma Correction, which I believe is still only available in Pro. You don't usually need tone mapping with GC.

Do you have AO turned on? Laurie

Nope, no AO on any of the lights

I had the same "thing" a few days ago as well.

I was trying out a new hair product I bought and in the final render there were these kind of black spots all over the characters face and (new) hair as well. Areal (?) renders had the same spots at the same places again. Turning the camera and the figure a bit fixed it tho.

As I recently updated to SR 2.1 and never had this happen before, it made my suspicious. The renders I did over the weekend were all good again. So no clue, as of yet, what it caused it, as I was not able to reproduce the spots again in any of the renders.

It went away, when I re-rendered, and only thing I changed was the Tone Mapping.  That being said, I am not convinced that just re-rendering would not have fixed it as well?

I don't know if just re-remdering would have fixed it. Nooooo idea. I just saw that with partial/areal renders they still were there.

btw .. I did not use tone mapping. IDL, gamma at 2.2 as well as BB's SSS shaders were in use.

I encountered the same things in Poser 2010 and 2012. I posted the results here
