Since 3Delight Studio Pro includes 3Delight For Maya, please refer to 3Delight for Maya Changelog for more information about recent changes.

10.0.140 - 2013-05-17

• Fixed some sources of bright speckles with the raytrace hider.
• Option “trace” “shareinstances” is now enabled by default.

10.0.139 - 2013-05-14

• Some fixes to dPdtime variable in the ray tracer.
• Fixed a self-intersection issue with ray traced displacement.
• Lights are now also accessible as named coordinate systems.

10.0.138 - 2013-05-09

• i-display can now save files in jpeg format.
• Fixed IPR and RiProcedural used together. Attributes were being lost.
• Fixed raytraced displacement artifacts.
• Improved derivatives in the raytrace hider. This should fix texture mapping problems that were visible on surface patch boundaries (especially visible when using the texture as displacement) (#4524).
• Less noise when using depth of field and the ray-trace hider.

10.0.137 - 2013-05-07

• Fixed i-display UI (no text) on debian based systems (ubuntu).
• Fixed RiMakeTexture and similar commands which were popping up consoles on windows.
• Fixed a sampling quality bug with progressive rendering (including IPR). This was making results much worse than they should be.

10.0.136 - 2013-05-03

• Fixed artifacts with the GI cache (#4498).

10.0.135 - 2013-04-30

• trace() now correctly samples the environment map even if the ray depth limit is reached. In that case, transmission rays will be used.
• Fixed excessive memory use when ray tracing shared instances.
• Added “samplelock” option to the “raytrace” Hider. One can choose to link the sampling patterns of trace() to the frame number or not.

10.0.134 - 2013-04-25

• Displacement shaders can now have the reserved “float __displacement_enabled” parameter to communicate if they are actually doing displacement, according to other parameters. When they are not, raytracing can be done faster and with less memory.
• Ray tracing hider now accepts the “samplemotion” toggle. This allows to disable motion blur while still providing correct motion vectors (#4434)

10.0.133 - 2013-04-23

• Fixed behavior of isoutput(Ci) for secondary rays.
• Fixed some installation issues on OS X.

10.0.132 - 2013-04-20

• Fixed some bright spots which would sometimes appear when using GI (#4463)

10.0.131 - 2013-04-18

• Fixed isoutput(”Ci”) to behave correctly, like isoutput(Ci). The later is still preferred.
• Fixed an occasional hang when using the GI cache in progressive render mode.
• Default texture filter for the ray trace hider is now “box”. Contrary to REYES, the quality in they ray-trace hider is controlled by pixel samples so an analytical gaussian filter is not appropriate as a default (if specified, the filter type is honoured). The net result is a substantial speed improvement in texture heavy scenes.

10.0.130 - 2013-04-15

• Slightly faster ray tracing, using less memory.

10.0.129 - 2013-04-11

10.0.126 - 2013-04-04

• Reduced memory use of shader instances.
• Faster shader method calls.
• Fixed a crash with ray traced instances and displacement.

10.0.125 - 2013-03-27

• Fixed some shader compiler bugs.

10.0.124 - 2013-03-22

10.0.120 - 2013-03-14

• Default texture coordinates for subdivision meshes now match what is expected by ptexture().
• Subdivision meshes now handle the special “facevarying float __faceindex” used by ptexture correctly. This has different interpolation rules than a regular facevarying variable.
• Added the bsdf() shadeop to use the same distributions as trace() with direct light in illuminance().

10.0.119 - 2013-03-08

• gather() now always generates ray derivatives according to the specified angle, regardless of the distribution used.

10.0.111 - 2013-02-16

• Corrected intersection problems affecting Interior shaders that use primitive variables. Such as the ones generated by 3Delight For Maya when using “particleCloud” node.

• Multiple-importance sampling has been added to the trace() function. This should reduce noise when using environments and BSDFs together.

10.0.104 - 2013-01-25

• Rays traced with trace() from REYES now have their position jittered even when no oversampling is used.
• Fixed missing normals with ray traced displacements when the displacement texture is fetched from a coshader.

• trace() accepts a new BSDF: “ashikhmin-shirley” (anisotropic blinn-phong model). Roughness in the v axis is specified by “roughnessv” and anisotropy direction is specified using “udir”.

10.0.103 - 2013-01-22

10.0.100 - 2013-01-11

• Fixed the trace() “blinn” distribution. “wi” parameter is now “wo”, it now accepts “roughness” instead of “sharpness” and also accepts “eta” if a fresnel term is desired.

• Fixed a crash in RifUnloadPlugins().
• Performance improvements.

10.0.11 - 2011-11-04

3Delight

• Fixed directory textures which were not recognized on windows.
• Multi-threading performance has been improved (for machines with a high core count). This concerns renders where message passing and string manipulation is used a lot.

10.0.10 - 2011-10-31

3Delight

• Fixed a multi-thread performance issue.

10.0.9 - 2011-10-19

3Delight

• Added support for vertex width on cubic curves.
• Add Option “trace” “depthaffectsptc”. This option states if ray depth should be honored when rendering point-based occlusion and color bleeding (on by default).
• Fixed rendering of interior shaders when the camera is inside the box which defines the volume.

10.0.8 - 2011-10-18

3Delight

• Fixed a bug with motion blur of object instances when both deformation and transformation blur are used.
• texture() calls are up to 4 times faster on secondary rays (such as textures viewed in reflections).
• Added the -mirrorx option to tdlmake to mirror latitude-longitude environment maps.

10.0.7 - 2011-10-14

3Delight

• Fixed some incorrect errors in the shader compiler.
• Fixed a stereo rendering bug which would cause objects to sometimes be missing.

10.0.6 - 2011-10-12

3Delight

• Fixed random crashes at the end of the render with 10.0.5 when using shaders compiled with a version before 10.0.5.
• Fixed a performance issue on windows.
• Fixed some incorrect error messages from the shader compiler regarding uniform and varying variables.

10.0.5 - 2011-10-07

3Delight

• Fixed a bug which would sometimes cause transparent objects to show up twice since 10.0.3.

10.0.4 - 2011-10-06

3Delight

• Fixed a crash when using the raytrace hider with interior shaders.
• Fixed behavior of atmosphere shaders in front of matte objects when the “standardatmosphere” option is set to 0.
• Improved quality and speed of point based occlusion/indirectdiffuse with narrow cone angles. Speed improvement is of 10%.

10.0.3 - 2011-10-04

3Delight

• Improved REYES multithread scalability. This is most visible when rendering dense geometry (such as hair) with simple hiding and shading (as when generating a typical shadow map).
• Multi-camera rendering of particles is now supported.

10.0.2 - 2011-10-01

3Delight

• Added gridmin() and gridmax() shadeops to the shading language.
• Fixed texture interpolation with the “box” filter when shading particles or using the Sx API and a blur of 0 is specified.

10.0.1 - 2011-09-26

3Delight

• Fixed thread safety of SxGetParameterInfo().
• Fixed a performance issue when reading huge strings (several megabytes) from a RIB.

10.0.0 - 2011-09-23

3Delight

• Fixed texture interpolation with the “box” filter when shading particles or using the Sx API.
• New implementation of the noise() shadeop. It is up to 3 times faster and has slightly improved contrast for 3D and 4D noise. The previous noise can still be obtained with Option “render” “compatnoise” 1 ( or in rendermn.ini: /option/render/compatnoise 1 ).
• subsurface() is 300% faster when called for secondary rays (such as subsurface effects seen in a mirror).
• Fixed a performance issue with ray tracing displacements which would cause a catastrophic slowdown with some geometry.
