8.5.44 - 2009-11-26

3Delight For Maya

• Updated the shader nodes AE popup menu; “Hide Shader Attributes” entry fixed and the menu is easier to access.
• Added “Hide attributes over x shader parameters” in the preferences.
• Added “Edit” menu in the relationship editor’s object pane; this menu allows to highlight in the objects pane currently selected objects, and to select currently highlighted objects.
• Flipped the surfacev maya fur primitive variable so it fits with what is output for regular geometry.

3Delight

• Fixed a crash bug that was triggered when using class-based atmosphere shaders and “standardatmosphere” was set to 0.

8.5.43 - 2009-11-17

3Delight For Maya

• Added a “Hide Shader Attributes” operation in the relationship editor contextual menu for shader nodes. Turning this on for shaders that have a lot of parameters makes the AE refresh much faster. It also hides these attributes in all other editors.
• Added a contextual menu in the shader AE. It currently offers “Hide Shader Attributes” and “Reload Shader”.
• Fixed issue with frame layouts when clicking “Copy Tab” in a shader node AE.
• Fixed issue with particle systems variable output where the default behaviour of outputing some default variables was sometimes ignored.
• Added “particleId” to the list of particle system variables.
• Added “Per Particle Color As Surface Color” attribute, which renames the “vertex color rgbPP” primitive variable to “vertex color Cs”.

8.5.42 - 2009-11-10

3Delight

• Optimized occlusion() and indirectdiffuse() on densely tessellated geometry. Scenes with such geometries will render up to two times faster. This includes all RiBlobby geometry.

3Delight For Maya

• Added several primitive variables available for output when rendering Maya Fur.
• Added a “Maya Fur” attribute group in the geometry section of the geometry attributes node. This attributes are meant to be attached to FurFeedback nodes and provide control on which primitive variable will be produced when rendering Maya Fur.
• Small fixes to keep the shader manager working with the new shader node types.
• Fixed bug with “Replace Shader With File...” operation in the relationship editor.
• Fixed bug when “Export UVs” option is turned on in Shave Globals (and when 3dfmShave plugin isn’t loaded).

8.5.41 - 2009-11-05

3Delight

• Introducing multi-camera rendering.

IMPORTANT: custom volume shader nodes should be updated to work properly in the relationship editor; their “shaderType” string attribute is expected to contain either “atmosphere” or “interior”. Look at DL_shaderNode.mel’s DSN_init(string $node) procedure for a suggestion on how to update old nodes.
• Fixed support for Shave globals’s “Export Normals” toggle when rendering without the “3dfmShave” plugin.

8.5.40 - 2009-10-29

3Delight

• Fixed bad area of points when bake3d() is inside a conditional.

8.5.39 - 2009-10-28

3Delight

• Added Option “netcache” “includepaths” and Option “netcache” “excludepaths” which will force some files to be always or never cached, ignoring if they are on the network or local.
• getshaders() now always returns co-shaders in the order that they were specified in the RIB.

8.5.38 - 2009-10-26

• Added mib_glossy_reflection material.
• Major improvements to the relationship editor’s responsiveness. The editor is fastest when no name filter and when “Show” menu options are all on. “3 panes, collection as passes” mode can still be slow at times.
• Added a “Duplicate Display” item in the displays popup menu (available when right-clicking above a specific display).

8.5.30 - 2009-09-16

• Introducing mib_illum_lambert and mib_illum_phong shaders.
• Fixed incorrect bounding box when outputting a RIB archive without transforms.
• Added “Composite Objects Behind” attribute in the geo attribs node, visibility section. It corresponds to ‘RiAttribute “hider” “composite”‘.

• Added “Select” option in some panes of the 3Delight Relationship Editor.
• The render pass “Layer to Render” attribute now defaults to “<current>”. IMPORTANT: The command line rendering will no longer render all renderable layers when the “-rp” flag is used to specify a render pass and when that pass’ “Layer to Render” attribute is not set to “<current>”.

• Fixed crashes when ray tracing with very high recursion levels.
• Added a DELIGHT_VERSION predefined macro to shaderdl.

• Fixed particles (RiPoints) not showing up in the image when display subsets are used.

The attribute name should now contain the class and type of the desired variable (eg. “delightVertexPointSomething” to output “vertex point Something”). This supports vertex/uniform/constant and point/vector/normal/color/float. The previous method without class/type in the name is still supported for uniform/constant color/float as well as constant string.

3Delight For Maya

• Modified the Shaders / Attribs panel “Show” menu in the relationship editor. It now offers “Volume Shaders as Atmosphere” and “Volume Shaders as Interior” options. Enabling only one of these two options controls if the relationship editor assign / unassign select volume shaders as atmopshere or interior.
