11.0.168 - 2015-05-25

• Undoing ray importance modifications introduced in 11.0.166. Even though it was an improvement in terms of consistency, some scenes were rendering slower than in previous versions for the same quality. This feature is now disabled by default an can be enabled using "Option "trace" "gammacorrectedweight" [1]"

11.0.167 - 2015-05-21

• Fixed sampling quality issues which sometimes occurred with high PixelSamples values.

11.0.166 - 2015-05-13

• Modified the way rays' importance acts on the total number of traced rays: it is now more conservative to take into consideration screen's gamma curve, this means noise in dark areas will be consistent with noise in bright areas.

  Warning
  It is necessary to lower the number of samples in materials and/or in the Render Settings for Indirect Illumination to regain performance.

11.0.165 - 2015-05-08

• Adding a "[float|color] stringhash(string)" shadeop which takes a string and returns a corresponding float or color hash.  This function can be used to output (as AOVs) color-coded object identifiers (or material identifiers) for further masking and compositing. 

11.0.164 - 2015-05-06

• Fixed crash in hair bsdf with excessive eccentricity.

11.0.163 - 2015-04-30

• Fixed CSG rendering with ray tracer.
• Fixed i-display keyboard input which was not working on some linux distributions.

11.0.159 - 2015-04-20

• Fixed incorrect execution of overlapping additive interior shaders in some cases.

11.0.156 - 2015-04-06

• Proper support of Blackman-Harris pixel filter. It is very similar to the gaussian filter which was already available.
• Path-tracer now handles large empty screen regions more efficiently. Renders that have a small "screen footprint" (e.g. one character in the middle of the screen) will render faster.
• i-Display: Improved visual transition when entering and exiting Contact Sheet mode (for displaying multiple image selections or image layers).
• i-Display: The size of the Mixer dialogue can be adjusted in height to display more of less mixing sliders.

11.0.155 - 2015-03-31

• i-Display: Flipping through layers using Layer → Next/Previous (Page UP/Down) now works with multiple selections.
• i-Display: When entering Full Screen, the Thumbnail, Label and Menubar are hidden temporarily. When exiting Full Screen, their state is restored unless changed while in Full Screen.
• i-Display: Save Image as… and Export as JPEG... now default to the path and filename of the image specified in the rendering options.
• i-Display: Fixed a bug with filename being truncated (characters following “.” in their name) when exporting JPEG or with Save All Images.
• i-Display: Fixed a bug preventing re-aranging thumbnails in Full Screen on OS X.
  

11.0.147 - 2015-03-03

• Improved ray tracer performance by up to 15% when using multiple specular bounces (#5746).
• Fixed interior and atmosphere shaders with raytraced instances.

11.0.142 - 2015-02-19

• Fixed potential hang with edit API.

11.0.141 - 2015-02-17

• Fixed error reporting in the exr display driver.

11.0.140 - 2015-02-11

• Fixed a bug with interior shaders, transparent surfaces and the raytracer.
• Partial implementation of volumeshadingrate option with raytrace hider. Setting a volumeshadingrate smaller than 1 will simply shade the volume at each sub pixel. For debugging purposes only.

11.0.139 - 2015-02-06

• Fixed a performance problem with area lights which have non quadratic decay.

11.0.138 - 2015-02-05

11.0.137 - 2015-02-01

11.0.136 - 2015-01-24

• It is now possible to send edits while IPR is suspended.

11.0.135 - 2015-01-22

• The ray traced version of subsurface() shadeop can now output the contribution of single scattering only (using the "singlescattercontribution" output variable) (#5638).
• The 'followtopology' parameter to ray traced subsurface() now works.  Highly scattering and curved surfaces might see an improvement in quality with this parameter enabled. The drawback is much significantly higher noise levels in the subsurface effect.
• Fixed the autocrop option of the exr display driver when outputting the Z channel. Infinitely large depth values are now considered as empty space  (#5646).

11.0.134 - 2015-01-19

• Improved RIB output speed. Acceleration for large RIBs is between 10% and 20%. Acceleration can reach 300% In very specific cases where RIB stream contains very little geometry but large amount of strings  (e.g. large amount of scene modifications when using the scene edit API). (#5680)
• -D option of renderdl is not available anymore.
• -id option of renderdl now tries to output all the cameras that are used in a multi-camera render (#1494).

11.0.132 - 2015-01-14

• i-display: Fixed crash that happened when loading an image of unknown format.

11.0.131 - 2015-01-10

• Deep EXR display driver produces files 10 times smaller than before, without noticeable loss of quality.
• Fixed subsurface sampling which was sometimes producing speckles. Speckles were appearing when a material has very different scattering properties for R, G or B. As an example, a material that was highly scattering in red and non scattering in blue (such as skin) could produce such speckles. Note that this might result in slightly lower quality for gray materials (with similar scattering for R, G and B), and these could require more samples (#5613, #5641).
• i-display: Copy & Paste functionality was producing bad images when pixels had values larger than 1. This has been fixed (#4428).

11.0.129 - 2015-01-06

• Fixed a bug which could cause interior shaders to produce garbage or appear stuck (#5667).
• Fixed depth in deep output with the raytrace hider (#5668). Previously, depth was computed as a distance from the point representing the camera. After this fix, depth is the orthogonal distance from the surface to the plane defined by the camera.

11.0.128 - 2014-12-29

• Faster execution of interior shaders (volumes) with the raytrace hider.

11.0.127 - 2014-12-17

• ribdepends now recognizes UDIM textures.
• Fixed license server connection error reporting.

11.0.126 - 2014-12-15

• Adding an option to the exr display driver to disable AOV name length limit (it is clamped to a maximum of 32 character now). You can add the following line to the rendermn.ini file to disable the clamping:

...

• Fixed an occasional crash with GI (#5654).

11.0.125 - 2014-12-03

• Fixed a bug with interior shaders (ie. fluids) not rendering for some buckets (#5642).

11.0.124 - 2014-12-01

11.0.111 - 2014-10-02

• Fixed IPR problems introduced in 11.0.110.
  
• i-display: Export as JPEG now asks for a location.

11.0.110 - 2014-10-01

• Improved progressive rendering. The progressive pattern has now a more standard progression and converges to the same render as for a normal, non-progressive, render. 

• Progressive rendering is now almost as fast as a normal, non-progressive, render. As a broad estimate, the progressive render has less than a 10% speed penalty compared to a normal render.

  Warning

11.0.109 - 2014-09-30

• i-display: Use more user friendly light names when using the light-mixer. 
• Fixed a possible crash with camera edits in IPR.

• Better environment variable update in Windows installer.

11.0.82 - 2014-06-24`24

• Hierarchical subdivision mesh edits now also edit the "identifier" "name" attribute so RiEditBegin() can address the saved attributes independently.

11.0.77 - 2014-06-05

• Fixed some filtering issues with raytraced displacement.

11.0.46 - 2014-03-06

• The opacity() method of shaders is no longer systematically run before surface().
