Changelog

• Fixed an issue in the rendering core affecting instances organized in hierarchies (#7212). This issue caused objects to be clipped.

3Delight for Maya

• Fixed Material Viewer. Viewing and editing of both shaders and environments are supported. 
• All 3Delight^NSI error messages are now shown in the Script Editor instead of the terminal. This is particularly important in Mac OS X and Windows where the terminal is not always available, making error messages not show at all.

OSL Shaders

• Added 3Delight Car Paint and Random Material.
• Added Random Color utility shader.
• Added Flake 3D texture shader.

• Further improvements on ray intersection bias. This solves #7179 and #7216.
• Fixed potential crash bug at the end of a 3Delight Cloud render.
• 3Delight Display has an updated and nicer About dialogue.

3Delight for Maya

• Improvements to the templates generated for auto-loaded OSL shaders.

OSL Shaders

• Added a Facing Ratio utility shader.
• Added a Worley Noise and a Flake 3D Textures.

• Added a progress indicator in 3Delight Display for 3Delight Cloud scene synchronization.
• Improve accuracy of ray intersection to remove various "bias"  problems.
• Fixed various issues with 3Delight Display lens tool.
• Removed various legacy include files from package.
• Fix rendering of OpenVDB volumes on 3Delight Cloud.

3Delight for Maya

• An NSI file export now has the same scene output as a batch render. This means frame buffer and overrides options are ignored (not included) in the NSI file.
• Fixed dlMetal presets (Presets menu in the Attribute Editor).

OSL Shaders

• OSL shaders can now declare a classification string. This is in preparation of an automated way to create Maya shading nodes directly from OSL shaders. This string has no effect in Katana. 

• User friendly error messages for 3Delight Cloud error conditions.
• 3Delight Display offers better performance and responsiveness for the 3Delight Cloud tab (sign in and activities). This is achieved by running all related operations in a separate thread.

• Fixed minor memory leak.
• Upon exit and reentry into 3Delight Display, the application will automatically sign-in to 3Delight Cloud account if user was signed in during the previous session.

3Delight for Maya

• Updated URLs for Help and updated About dialogue.
• Removed obsolete icons.

• 5% to 15% faster rendering, depending on the scene.
• Fixed a problem with refractions (GGX BRDF) causing noticeable darkening.
• Fixed an error on linux when using 3Delight from python.
• Update of the first passes of a live render are now much faster (up to x2 times faster).
• Faster time to first pixel for scenes with large emissive meshes. Scenes with millions of light sources could start as much as x10 times faster.
• Added support for rendering VDB velocity from three float grids instead of a vector grid.
• Fixed some live render crashes related to instances.
• Fixed VDB emission.
• Added new python binding to NSI.
• Fixed changes to camera shutter in live render.
• Improve performance of sky shader.
• Fix performance of displacement after a change in live render.

3Delight for Maya

• Improved VDB rendering speed in viewport.
• Add support for Maya's Light Editor. This includes ability to output a light group as a multi-light layer.
• Add Color Blend utility node. This node has a similar functionality to the Layer Shader.
• Better support of Light Linking. Light links to sets and shading groups are now supported.
• Fixed a problem with instanced objects when each instance has a different shader.
• Support Maya's built-in UDIM tag, including support for UDIM tiling on file node.
• Improved UI for all materials and shaders.

3Delight for Katana

• Instantaneous opening of VDB files, even large ones.
• Fixed a crash with some VDB files.
• Draw lights behind the selection too instead of in front (usability suggestion by Matthew Bennett).
• Multi-Threaded scene export and scene export optimization.
• Find OSL shaders without Katana Resources.
• Various fixes to XGen loading.
• Do not link with Katana's Python libraries anymore. Those are not needed.
• Implement automatic conversion of textures into TDLs (mip mapped tiff files).
