Yep. It was always a setting in the material. That's what I mean by saying I'll make the default unit for the thing 1 meter so you likely won't notice it in the future. However-- it still does require additional calculation so you should get rid of it in materials where it isn't necessary.

The 0.2 appears when you bring in an existing glass material, though I don't know what setting is creating it. Was there an attenuation setting before? Maybe it was there but the effect was not so dramatic.

So where is the 0.2 coming from? There shouldn't be any when you create a new material. Do some of our stock materials have some?

<p>I really just moved some stuff around on the page. Your material, like Peter's, already had some attenuation which crept in there. The only additional setting is the Direction one. I'm likely going to break the old Translucency setting and the new Scattering setting into two settings so this stuff is going to change again in a few days.</p>

<p>Yes. Roy has added attenuation in and set the default to 0.2. So it now appears in every material, new and old.</p>
<p>This is fine for small glass objects (set the preview size to 100 and see), but no good for windows and glass partition.</p>

<p>Roy,</p>
<p>I have no way to go back and check now but the glass I speaking of just had a very high intensity with no transparency. The new dialog has added the subsurface scattering on its own.</p>

<p>The default sphere is 1 meter across (diameter, I think). Attenuation means the probability of an absorption event occurring per cm. Change either the units of the Attenuation or the scale of the preview object and you'll see the effect better.</p>
<p> </p>
<p>I'm proposing changing the default attenuation unit to meters, which should make the thing look pretty similar to before. This is still a good setting to get rid of in your glass-- it will trigger an SSS calc. which may be costly.</p>
