Changelog 8.0

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.
Improved deep shadow map creation time and reduced the amount of temporary disk space used.

Fixed cleanup of per thread and global data in RslPlugin.

3Delight For Maya

3Delight shader nodes now have distinct node types and outliner icons.
The relationship editor now has separate “Show Atmosphere Shaders” and “Show Interior Shaders”.
Fixed some issues in the relationship editor with custom shader nodes. 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

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.

Fixed particles (RiPoints) not showing up in the image when display subsets are used.
Fixed a crash with signed textures.
Fixed an infinite loop in ribdepends.
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.

8.5.13 - 2009-06-04

3Delight

Fixed rendering of curves with negative width.
The OpenEXR libraries to use may now be specified with the DL_OPENEXR_LIBRARIES environment variable, in case several versions are installed or they are not in the default location. This should take the full name of the library to load (eg. libIlmImf.so.6.0.0 or /usr/local/lib/libIlmImf.so ).

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. When both options are enabled, the relationship editor will ask for the assignment type.

Fixed ignored assignments when rendering objects in a namespace.

8.0.54 - 2009-04-16

3Delight

Improved the license server’s behavior under heavy load or with slow (eg. swapping) clients.

8.0.52 - 2009-04-14

3Delight

New, more efficient space partitioning algorithm is now the default for the ray tracer. It will start up faster, render faster most of the time (much faster with displacement) and use less memory. 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

3Delight

Fixed compilation of shaders which initialize arrays with a single scalar value. This was broken in 8.0.50.

3Delight for Maya

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.

8.0.49 - 2009-04-03

3Delight for Maya

Fixed shadowmap fov for spotlights with a penumbra.
Fixed render sets when they contain instances of groups.

3Delight

Improved behavior of shadowmaps with a scale in their camera transform.
Fixed behavior of a rare case of shadowmap lookup.
Fixed built-in variables (P, s, t, etc) which would not show up in displays if the surface shaders are not using them.
Fixed motion blur of patch type RiPoints.

3Delight for Maya

3D texture nodes now use texture reference objects if the appropriate geo attrib is set to export the reference geometry.

8.0.47 - 2009-03-19

3Delight

Added “newer” parameter to RiMakeTexture().
Changed handling of the arrays in Ptc API. This makes arrays incompatible with 8.0.46. The API now accepts and returns types of the form “color[4]” where necessary. Point clouds without arrays are unaffected.
Fixed a crash with some polygons having uniform string parameters attached.
Added the Dspy... helper functions to ndspy.h and 3Delight.

8.0.46 - 2009-03-17

3Delight

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.

3Delight for Maya

Worked around a bug in maya which caused occasional crashes when renaming parameters of a rendermanCode node.
Translated hypershade nodes now use the reflectionLimit attribute.

Improved behavior of network rendering when some jobs die.
Fixed Attribute “dice” “referencecamera”.

3Delight for Maya

Added a “dicing camera” attribute in the geometry attributes node (in the “Culling and Dicing” section).
Environment variable lookups for variables which don’t exist are no longer removed from strings. They are instead output untouched so 3Delight can resolve them later.
Fixed attribute/shader assignment to instances. They would sometimes end up stuck with the same attributes.
Introducing the “3Delight Relationship Editor”. The “Shader Manager” and the “Attribs Node Manager” are now considered deprecated.

8.0.39 - 2009-02-17

3Delight

texture3d() now returns 0 when the file exists but some of the requested channels are missing.
The dirmap option is now applied to point cloud files created with bake3d().
