• Removed "specular" depth. Rays are now tagged as wither reflection or refraction depending on the direction they take when interacting with a specular BRDF. This leaves us with four different ray depths: reflection, refraction, diffuse

•  and hair. This work also fixes refraction depth problems (was impossible to control because of a bug with the specular ray-type overriding it).
• Fixed problems when modifying displacements during live render.

3Delight for Katana

• The DlSetting's Multi-light selection is now applied on all image layers that are using a Shading Component AOV.

• renderdl: restore the "-t" and the "-catrib" command line option. The "-catrib" option has been renamed to "-cat".

NSI

• NSIRenderControl()

•  now accepts a "stoppercallback". The callback is called, along with user data, when a render is done. This allows for asynchronous renders to communicate completion to parent program.
