**Short description of error**
Christensen-Burley make the materials dark in cycles if the mesh have been scaled up or down without applying the scale transformation.
**Exact steps for others to reproduce the error**
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]
I recently opened an old file (happen on most other files) on this Alpha version and I noticed that some of my meshes with SSS materials looked darker but not all of them even if some were using the same material.
After looking around the difference between meshes I realize it was happening only to the meshes that I had scale up or down but didn't applied scale transformation, so when I did applied the scale transformation it fixed the bug until the mesh was scaled again, but I was wondering if it would be an issue if my meshes are scaled during an animation and I wouldn't be able to fix it since the mesh would look dark even if I change the Subsurface amount to the smallest value.
Also please don't remove Christensen-Burley, if I use a bevel shader with sss it doesn't work right with any on the random walks, thanks!
Edit: I just check again and if you scale only one axis (ex. press S to scale then Y) only the faces on that axis get darker if either you scale up or down. Weird
