chad ashley takes a look at the “proper” Linear Workflow for rendering with V-Ray which can take care of some issues in rendering such as low level noise. Chad also explains the differences between how 3ds MAX handles Linear Workflow, and how it differs from this technique.

Things to take away. If you turn on gamma workflow in your preferences and work at 2.2 in 3ds Max, Vray may not see enough differences in those dark pixels to properly AA them.
