11.0.46 - 2014-03-06
- The opacity() method of shaders is no longer systematically run before surface(). This may require updating some hand coded shaders to either include the opacity code in surface() or make an explicit call to opacity(). The opacity() method is now called directly by 3Delight only when the opacity is all that is needed, such as for transmission rays.

i-display: Two useful LUTs have been added to the View -> Color Profile menu: REC 709 and sRGB.
Additionally, LUTs can be changed anytime (there were previously applied on images at load time)

11.0.28 - 2014-01-17
- Added "arealightcontribution" parameter to the trace() shadeop.

11.0.25 - 2014-01-08
- The ray-traced version of the subsurface() shadeop now supports the "model" parameter as well as a new "singlescatter" parameter. The model can be either "classic" (for the classic dipole) or "betterdipole" for the better dipole model. The "singlscatter" parameter is a scalar ranging between 0 and 1 indicating the strength of the single scattering effect. It is recommended to set this value to 1.
- Trace subsets now support intersection of group lists with the & operator.
- Fixed shader space on alternate cameras when using view dependent shading with REYES.
11.0.24 - 2014-01-06
- Fixed licutils which would not return a hostid on some newer linux distributions.
11.0.23 - 2014-01-03
- Fixed bugs in subdivision memory statistics. Memory consumption would sometimes appear much higher than it is.
- Fixed bugs in area light sampling.
- Added "float pixelaspectratio" and "float imageaspectratio" to RiMakeTexture().
- TIFF display driver is now able to write many layers/channels into the same file. Layers can have different bit depths and different data types (#4955).
- Fixed a hang with some combinations of subsurface and ray traced displacement.
11.0.22 - 2013-12-17
- Fixed some crashes to area lights (#4944).
- "transmission" type rays with trace() now always cause surfaces to shade black, regardless of the hitmode. The transmission output itself is unaffected.

11.0.9 - 2013-10-30
- Improved quality of environment map sampling with trace().
11.0.8 - 2013-10-28
- Fixed some environment map sampling artifacts which would not go away easily even with large sample counts. This can have negative impact on results with small sample counts in some cases. In most cases, it is not noticeable either way.
11.0.7 - 2013-10-24
- Improved quality of environment map sampling with trace().
11.0.6 - 2013-10-22
- Fixed grouping membership tests for instances/procedurals. Grouping membership declared outside of instances/procedurals were not considered.

- Implemented "__CPUtime" AOV with the raytrace hider.
11.0.5 - 2013-10-11
- Fixed getvar( null, ... ) with uniform primvars and the raytrace hider (#4846).
- Added documentation and example for the Scene Edit API.
11.0.4 - 2013-10-09
- Fixed a bug in the Scene Edit API. Some light edits were ignored. This problem has been introduced in 11.0 .
- Added the "glass-ggx" distribution to trace() and bsdf().
11.0.3 - 2013-10-06
- Fixed multi-camera bug with path-tracer : there was no motion blur in secondary cameras (#4828).
- i-display: Image pan/zoom is now done with left mouse button instead of middle mouse button. Consequently, image browsing is now with middle mouse button. Here is a description of the changes in more details:
| Mouse Buttons | Actions | Previous Actions |
|---|---|---|
| Middle Mouse Button | Image browsing. With SHIFT modifier: Fast image browsing (for playback scrubbing). | Image Panning. With SHIFT modifier: Zooming. |
| Left Mouse Button | Image Panning. With SHIFT modifier: Zooming. With COMMAND modifier: Define Zooming region. | Fast image browsing (for playback scrubbing). With SHIFT modifier: Image browsing. |
