<div dir="ltr">I'm not sure about this, in my opinion this is a setting that should be in the shading nodes. It seems to me somewhat arbitrary that you would have a global setting for this. If it's really needed it could be an object or material setting, but I would rather not have it.<div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Since we now have a proper Gaussian falloff for the SSS shader, I've been playing around with implementing the sum of Gaussians technique for rendering skin as explained in GPU Gems 3 and this year's SIGGRAPH talk "OSL The Great and Powerful". It's very fast to set up and is so far giving nice results. However, it uses 6 layers of SSS data, each with its own individual scale, some of which are very small numbers. Changing these scales one by one proves to be tedious when trying to get the scale of the material to match up with the scale of the object to which it is applied. I'd like to propose a global SSS multiplier, perhaps in the scene panel, that would allow us to quickly find the sweet spot for SSS shading, especially when using multi-layer setups. It would be especially useful for the SoG method where certain values are measured real-world levels, but where modeling scale may not be in real world units. Any thoughts on this matter would be appreciated.<div>
