Will there ever be a fix for the Random Walk SSS? I've been waiting for months and it's still the same depth limit "bug" since then.
There are some others who have already reported the bug here.
Thanks.

The minimum radius is clamped to avoid the problems that happen with loss of precision with really small values. Similar problems happen if you're really really far from the origin. This is a limitation of floating point precision, so unless we can come up with some alternative approach or tradeoff, the clamping stays.
Hey Stephen.
It's a shame to hear that. I can remember it worked in early releases. Maybe it was wrong in some way, but there was a result. The only way to get something useful is to scale up the whole scene. (Not really a solution for complex setups...).
Its one of the features that makes Arnold so unique compare to others engines. I hope there will be some improvements.
Thanks for your feedback.
