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.

• Fixed fresnel()’s transmission vector when N.I > 0. This may change shaders which were arguably broken.

3Delight For Maya

• Added support for the vertex class in the output of custom primitive variables on shapes from maya attributes. 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.
• Fixed issue with parented place3dTexture nodes; their placement matrix would appear static.
• Fixed issue with delight node assignments on nodes with multiple namespaces.

If you find otherwise, let us know. The old algorithm can still be enabled with this key in rendermn.ini:/option/trace/partitiontype space

3Delight for Maya

• Improved the performance of scene translation to 3Delight, which reduces the overall time spent for rendering in Maya.

8.0.51 - 2009-04-09

• Fixed an error message when opening/importing a scene caused the plugin to be loaded.

8.0.50 - 2009-04-07

3Delight

• Switched to a newer compiler on windows for a faster 3Delight. 32-bit windows packages now require a processor with SSE2 support. This means a Pentium 4/Athlon 64 or more recent. If you need packages for older CPUs or systems, please contact us.

8.0.45 - 2009-03-16

3Delight

• New OS X universal package which includes ppc, i386 and x86_64 architectures. Houdini users will need this as Houdini is 64-bit only on OS X. You can also grab it if you want to run 64-bit for whatever reason (it’s about 10% faster). Note that if you render directly from Maya you will not be using 64-bit code as Maya is 32-bit and will thus load the 32-bit plug-in. Use the background render mode to work around this.
• Fixed motion blur of subdivs when there is deformation which extends beyond the shutter range but the transformations there are not well defined.

8.0.44 - 2009-03-12

3Delight for Maya

• Fixed possible issue for sprite particles with a height of 0.
• The <camera> tag is now replaced with a modified render camera name that contains only characters legal in file names.

8.0.43 - 2009-03-10

3Delight

• Linux packages are now built with a more recent compiler. This provides significant speed gains for most renders and also means we link with a more recent C++ library on 32-bit linux (libstdc++.so.6 instead of libstdc++.so.5). The 32-bit linux packages now require a CPU with SSE2. This means a Pentium 4/Athlon 64 or more recent. If you need packages for older CPUs or systems, please contact us.
