8.0.45 - 2016-09-12

  • Better handling of attribute changes on 3Delight shaders to reduce the number of shader recompilations. This also resolves issues related to applying a "preset" or keying one of these shaders.

8.0.44 - 2016-08-26

  • Version number bump for the free package update.

8.0.43 - 2016-08-24

  • Fixed issue when rendering XGen objects on OS X (issue 6359).
  • Fixed error when the render camera uses an Image Plane that is set to an unsupported image type (Texture and Movie types are not supported) (issue 6371).
  • Fixed issue when rendering XGen objects which is more likely to happen when the 3Delight_XGen project path is set to a Windows network drive (issue 6369).
  • Fixed issue when rendering multiple references to the same XGen objects (issue 6378).
  • Plug-in for Maya 2017 now available for OS X, Windows and Linux.
  • Textures that are automatically converted to TDL format by 3Delight for Maya are now named with a ".tdl.tif" extension. Previously converted textures whose filename end with ".tdl" will be ignored and can be deleted.
  • Now automatically converting all textures when a File 2D Texture node has its Image Sequence attribute turned on.

8.0.42 - 2016-07-19

  • Fixed issue when rendering instancers with OSL Render Pass
  • In order to avoid Maya issues in the Hypershade, the 3Delight shading node type names have been changed.
    • This will resolve error messages related to the Hypershade Property Panel when selecting a 3Delight Material shader (in Maya 2016), for newly created material nodes.

    • Existing scenes will not be modified by this fix. They will render as before, and will continue to produce error messages in the Hypershade when selecting one of the 3Delight materials.

    • It is possible to migrate existing scenes to the revised shading node type names, if desired.

      The DL_migrateAllDeprecatedShadingNodes() procedure

      The DL_migrateAllDeprecatedShadingNodes() procedure is provided as a tool to help migrating existing scenes. 

      • The procedure will look for all old 3Delight material nodes in the scene;
      • Existing values, keys & connections are migrated to a newly created shading node that has the revised type name;
      • Hypershade shader assignments will be preserved. 
      • After the procedure has completed, the old shading nodes will be placed in a old3DelightShadingNodes set, for user inspection and deletion. 

      This migration procedure is not applied automatically; it must be called by the user. It is recommended to inspect the resulting new nodes to make sure all settings have been carried over. Please note that this procedure should be ran on each referenced scene.

  • Fixed issue that prevented creating 3Delight materials by pressing the tab key in the Node Editor.
  • The 3Delight materials are now only listed in the 3Delight section of the Hypershade. Previously, they were also listed in the Maya section. You may need to update your Favorites materials to reflect this change.
  • Fixed issues when using the Favorites material feature with 3Delight materials.
  • Fixed issue where IPR session would ignore many render pass settings, such as the Collection to render (issue 6354).
  • Fixed an issue slowing down 3Delight for Maya output when there are multiple light sources (issue 6355).


8.0.41 - 2016-06-29

  • Minor cosmetic fixes in Maya 2016 and up.

8.0.40 - 2016-06-28

  • Fixed incorrect rendering of incandescence in some VDB files.

8.0.39 - 2016-06-23

  • In order to avoid several Maya issues, the 3Delight for Maya plug-in file name has changed. Old scenes will continue to work and the change should be seamless. See this page for details and recommendations for Plug-In Manager settings.

8.0.38 - 2016-06-18

  • Fixed issue where a Render Pass set to produce a point cloud but no image layers would render nothing at all.
  • Fixed hanging OpenVDB renders on windows.

  • Deprecated the Smooth UVs attribute of the Polygons section in the Geometry Attributes node.

    Starting with this version, the default "Smooth UVs" is set the the maximum quality achievable by 3Delight (full). Scenes may exhibit a slightly different UV interpolation unless the now deprecated Smooth UVs attribute was already used.
  • Fixed issue when invoking Maya's "Render" utility with some Maya versions.

8.0.37 - 2016-06-14

  • Revised Linux configuration: MAYA_MODULE_PATH should be set to $DELIGHT/maya/modules; all other MAYA_*_PATH assignments (except MAYA_RENDERDESC_PATH) are now obsolete. The 3Delight scripts that set up the shell environment have been modified to reflect this. This change should be transparent for most setups.
  • Simplified the Polygons section in the Geo Attributes. Several attributes of this section have been deprecated.
  • Attempt to fix possible MEL error related to the (deprecated) 3Delight Geometry Modifiers.
  • Attempt to fix possible MEL error that makes a Render Pass appear for only a second or two in the Attribute Editor, before it is emptied.

8.0.36 - 2016-06-09

  • Attempt to fix a possible "division by zero" MEL error when rendering.

8.0.35 - 2016-05-29

8.0.34 - 2016-05-25

  • Fixed several OpenVDB rendering bugs.
  • Better fix for VDM ramp attribute values saving (issue 6273).

8.0.31 - 2016-05-09

  • Fixed bug with VDB ramp attribute values when opening a scene (issue 6273).

8.0.30 - 2016-05-05

  • Fixed bump mapping for objects with invalid texture coordinates. This resulted in zero sized normals.
  • Extension attributes on shapes are not keyable by default anymore. They will still be displayed in the Channel Box editor.
  • OSL: fixed issue with displacement shading network parsing.
  • Added "Render as Bump" extension attribute for displacement shaders (issue 6250).
  • Fixed issue with XGen nodes in references that would not render at all.

    • Fixed incorrect gamma correction for color values coming from non-Hypershade nodes in a displacement shading network;
    • Fixed incorrect gamma correction for keyed color values in shading networks, except for displacement shaders (issue 6138).
  • Sent proper output file name to interactive framebuffers such as i-display so the resulting image could be saved in a file of the expected type.
  • Fixed a bug with VDB incandescence (fire). It was incorrect at low quality settings.
  • Improved VDB sampling.

8.0.29 - 2016-03-28

8.0.27 - 2016-03-07

  • Cumulates 3Delight changes since previous package.

8.0.26 - 2016-03-02

  • Fixed colour management issues with OSL renderings, notably wrong displacement shader colours (issue 6174).
  • OSL Render Settings for Maya 2015 and older now have a Monitor Color Profile attribute; the colour management system is described here.
  • OSL renderings for Maya 2015 Extension and more recent use the Maya built-in color management system, described here. There are no 3Delight for Maya additional controls required in this case.
  • There is a Monitor Color Profile attribute that will be displayed in the OSL render settings in Maya 2015 Extension and up, if the loaded scene was saved in an older Maya version. This is a backward compatibility feature to maintain the rendered look produced by the older Maya version.
  • Fixed area light and environment textures that appeared upside-down in OSL renderings (issues 6188 and 6191).

8.0.25 - 2016-02-26

  • Fixed RifFilter plugins which were only working on the first frame of an animation sequence (issue 6184).

8.0.24 - 2016-02-23

  • V coordinates for OSL renderings are now output as defined in Maya, instead of being flipped. The OSL place2DTexture has been changed accordingly. This resolves an issue where using a file node without a place2DTexture node would produce incorrect results (issue 6169). This only affects OSL renderings.

8.0.23 - 2016-02-19

  • OSL render pass RIB filename now supports the <pass> token (issue 6143).
  • Fixed possible 3Delight error messages when editing some VDB shape attributes once it has been rendered.
  • Added a Use render Settings' Image Size toggle in the OSL render pass. It is on by default; the Common tab now shows the standard Maya Image Size section.
  • Moved the Quality group of attributes up in the OSL render pass.

8.0.22 - 2016-02-09

  • Fixed a problem where modified values for 3Delight extension attributes would not be restored properly after an open scene operation. This prevented proper values from being used when rendering with the Render command line utility.

    User-defined light shapes that are using 3Delight extension attributes will minimally require some initialization command.

  • Added Illumination From extension attribute on Paint Effects shapes and Maya Hair shapes.
  • Added extension attributes on NURBS curve shapes to allow rendering them.
  • Fixed plug-in initialization in Maya 2013. Pre-release features are available only for Maya 2014 and up.

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.

  • 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.

  • 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)

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.

11.0.110 - 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.

    Scene edits (IPR) appear delayed in this version, do not update to this version if IPR is needed.

11.0.109 - 2014-09-30

  • Minor optimizations for hair and fur rendering.
  • Minor improvements Just In Time compilation in the shader compiler.

11.0.108 - 2014-09-24

11.0.85 - 2014-07-07

  • Fixed incorrect global illumination intensity in some corner cases. In particular this could happen when tracing very low sample counts (#5409).

11.0.84 - 2014-07-02

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