Changelog

8.5.1 - Upcoming

• • 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.

     More Info...

    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.

• 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.

8.0.30 - 2016-05-05

  • 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.

• 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).

8.0.23 - 2016-02-19

• OSL render pass RIB filename now supports the <pass> token (issue 6143).

• Added Illumination From extension attribute on Paint Effects shapes and Maya Hair shapes.
• Added extension attributes on NURBS curve shapes to allow rendering them.
