9.0.132 - 2011-09-19

3Delight

• Added “asrgba” option to the exr display driver. This forces the output to be named “RGB” / “RGBA” in the file, regardless of the AOV name.

9.0.131 - 2011-09-14

3Delight

• Fixed bad normals in some cases with the Sx API.

• Added “Bias” in “Point Cloud”§ion of Global Illumination attributes.

9.0.128 - 2011-08-26

• Added attribute “dice” “lodreferencecamera” which allows specific cameras to be used to compute the detail level to render (for LOD with RiDetail/RiDetailRange).
• When the above is not specified, 3Delight now uses the “dice” “referencecamera” cameras if they are set. If that is not specified either, it falls back to the main camera.

3Delight for Maya

• Point-based Full global illumination now supports environment intensity, environment colour gain, environment colour offset and fixed the effect of colour bleeding intensity.
• Fixed AOV output of point-based Full global illumination.
• Changed default value of “Cast shadows from Environment” to ‘off’.
• Changed interpretation of Render Pass → Global Illumination → environment intensity for “Fast Image-Based Lighting” and “Full Global Illumination” effects. Older scene will be automatically updated to continue producing the same images; once saved they should not be used with older 3dfm versions.
• Added Global Illumination attributes to basic render pass.

9.0.127 - 2011-08-24

3Delight

• Fixed ray tracing of displaced triangles.
• Fixed inefficiency when using a dirtex texture with the network cache.

9.0.126 - 2011-08-22

3Delight

• Improved quality of “maxdist” with point based occlusion() and indirectdiffuse().

3Delight for Maya

9.0.125 - 2011-08-18

3Delight

• Attribute “trace” “maxdiffusedepth” and Attribute “trace” “maxspeculardepth” are now supported and offer a finer control over ray depths. Previous global limit (specified by Option “trace” “maxdepth” is still supported and specifies the total maximum depth. Finer control over ray depths can dramatically improve performance.
• Fixed handling of “object” space in the Sx API.
• Fixed the environment map looks in occlusion()/indirectdiffuse() to take falloff into account.

• Default filename now includes frame number for images, RIB and RIB fragment files.
• Added “progressive raytrace” in the Render Pas → Advanced → Hider option menu. Used with a frame buffer-style display driver, it allows a coarse rendered image to be quickly displayed; it then is progressively refined.

9.0.122 - 2011-08-09

3Delight

• The gather() construct can now query “primitive:P” and “primitive:N”. This will work even when no shader is run at the ray intersection.
• Fixed output of “a” alone when used with a display subset. It would previously always render black.
• Fixed subsurface() crash when used with subdivision mesh instances.
• Added the SX_RI_PARENT_CONTEXT constant to the Sx API which allows for a context to inherit the options and attributes of the currently active rendering context. This is intended for use in procedurals.

3Delight for Maya

• Added support for ‘RiAttribute “user”’ and ‘RiOption “user”’ using extra attributes on the Render Pass node, similar to what already exists for ‘RiAttribute “user”’ on the geo attribs nodes.
• Fixed multi-threaded inconsistencies with “baldness” fur attribute map “Noise” attributes. Important: Maya Fur using baldness will produce slightly different renderings.

9.0.121 - 2011-08-05

3Delight

• Fixed the side of ‘Sides 1’ surfaces which is seen by shadow(”raytrace”) or Attribute “light” “shadows”. These surfaces now cast shadows if they are facing the light, not if they are facing the object being lit.

3Delight for Maya

• Fixed the side of ‘Sides 1’ surfaces which cast raytraced shadows, as above. Note that this is now the opposite of the Maya Software renderer but the same as mental ray. It is also coherent with the behavior of shadow maps.

3Delight for Maya

• Added “Shading Frequency” attribute in the geo attribs node’s motion blur section. Note: shading frequency is now “per frame” as opposed to “per segment” in the previous versions.
• Now shading motion blurred objects with more than 2 motion samples only once per frame by default. Previously all objects were shaded once per motion segment. This new default can be overridden by a geo attribs node with the “Shading Frequency” attribute.

9.0.112 - 2011-07-11

• Faster loading of textures. This will have a positive impact on renders which access a lot of texture data on multi-core machines.
• Fixed occasional crash when raytracing shared instances.
• Fixed missing surfaces when raytracing scaled shared instances (#3385).

10.0.17 - 2011-11-30

3Delight

• Added ability to specify polygonal bokeh shapes (aperture control) (#3363).
• Faster motion blur raytracing. Speedups are proportional to the ple of tile size.

3Delight

• Improved memory use of point cloud based subsurface.

9.0.5 - 2010-01-05

3Delight

• Fixed ribdepends to track Shader commands (coshaders).
• The ‘licserver’ utility can now read license keys that are split over several lines.
• 3Delight can now produce and use textures larger than 4GB.
• Fixed a crash in point based indirectdiffuse/occlusion with some shaders.

9.0.4 - 2009-12-29

3Delight

• Fixed a crash with coshader method calls with array parameters introduced in 9.0.4.

9.0.3 - 2009-12-28

3Delight

• Fixed reporting of displacement bounds for shaders with a displacement method.
• OS X installer now updates the environment for zsh users as well.
• Fixed handling of arrays of length 0 in C API and RIB.
• Fixed subsurface behavior with very small scale.

9.0.2 - 2009-12-17

3Delight

• Fixed spline() shadeop with “solvebspline”, “solvebezier” and “solvehermite”.
• Fixed thread safety issue with procedural’s Free function.

9.0.1 - 2009-12-15

3Delight

• User procedurals inside inline archives are now correctly delayed.
• Fixed “shader” space in coshader methods.
• Fixed OS X ppc build.

3Delight For Maya

• Fixed custom shader node listing in the assignment panel.

9.0.0 - 2009-12-10

3Delight

• Point-based occlusion and indirect-diffuse now benefit from “irradiance” “shadingrate” controls. This makes the algorithm about two times faster in the default case.
• Point-based occlusion quality has been improved: concave geometry corners render much better (also fixes “white line” problem).
• Fixed a problem with multi-camera rendering: objects invisible to the main camera could disappear in secondary cameras.
• Fixed minor problem with blobby rendering in multi-camera: shading rate was not properly computed.
• Fixed a bug in photon map generation.

3Delight For Maya

• Added a “facing ratio” aov.
• “particle width space” attribute has new “Object” default value that matches 3Delight.
• Added support for per particle system string attributes.
• Fixed relationship editor’s shaders and attribs contextual menu that could be broken with custom shader nodes.
• Fixed issue when registering custom shader nodes in batch mode.
• Added misss_* shaders.
• Dropped support for maya 8.0.
