Fixed output of string array shader parameter values.

8.0.56 - 2009-04-21

3Delight

Improved bake3d with “interpolate” set to 1.
Improved licensing behavior when a client only gets some of the licenses it needs. This used to cause some licenses to be held up for about 5 seconds after the client finished.

3Delight for Maya

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.

8.0.53 - 2009-04-15

3Delight for Maya

Fixed plugin which did not load in maya 2009 on 64-bit linux.
Further improvements in the performance of scene translation to 3Delight, which reduces the overall time spent for rendering in Maya.

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.

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

Fixed licutils and the license server of the 64-bit OS X package.
Fixed ptcview -info which only showed the last channel of the file.
Fixed handling of arrays in bake3d() and texture3d() shadeops.

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.

The master process in a network render will now timeout after 10 minutes if some jobs have not yet started properly. This can be configured with the /3delight/networkrender/jobtimeout entry in rendermn.ini.
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().

3Delight for Maya

8.0.38 - 2009-02-13

3Delight for Maya

Fixed hypershade translation on Windows which was broken in 8.0.37.

Old .sdl files are no longer left behind for hypershade networks which fail to compile.

8.0.36 - 2009-02-05

3Delight for Maya

Fixed file path expressions for string attributes of rendermanCode nodes. This also applies to connected attributes.
Added “Depth Filter” and “Volume Interpretation” in the Shadow Maps section fo the render pass. These attributes only affect shadow maps rendered in that render pass’ primary or secondary displays.

8.0.35 - 2009-02-03

3Delight for Maya

Added a “Output Render Progress” checkbox in the statistics section of the render pass, which outputs to stdout the rendered % of the display being rendered.
Added a “-prog” flag to the command line interface (via the Maya Render utility) to control the new “Output Render Progress” render pass attribute.
Added “sourceshapename” and “sourcefullshapename” tags for hypershade .h files. They behave like “sourcename” but give the shape name and full dag path to shape respectively.
Fixed broken “3Delight Geometry Modifiers” menu (and on Maya 2009, Attributes menu as well).
Added support for <camera> tag in string attributes; it gets expanded to the name of the camera shape used for rendering.

3Delight

The dirmap option is now applied to the current working directory and the RIB file names when doing a network render.
Fixed a crash with particles using width in “raster” space.
Fixed hang in windows to linux network render.
Added the ability to set shader instance parameters using a new category of attributes: Attribute “shaderparam” ... This is carried on the attribute stack like any other attribute. It is applied to surface, displacement and standard atmosphere shaders.
renderdl now behaves better on linux when trying to restore the current directory in a network render when there are symbolic links in the path.
The RIB parser can now lookup user attributes and options inside strings, such as “sometext${user:my_attribute}othertext”.

3Delight

Fixed a deadlock in subsurface() in some cases involving multiple groups.

3Delight for Maya

Worked around a memory leak in the Maya 2008 and 2009 C++ API. This would be most visible when exporting several frames of a complex scene to RIB.
