6.5.54 - 2007-11-02

3Delight

Fixed a deep shadow map bug which sometimes caused the shadows of nearly opaque objects to be too light.

The samplebase parameter is now used by the occlusion() and indirectdiffuse() shadeops and defaults to 1.

Added “int progress” and “int separateplanes” to RiMakeTexture() which enable the corresponding flags in tdlmake.
Empty searchpaths (such as in “@:”, “:” or “/aaa/::/bbb/”) are now ignored. They would previously break automatic shader recompilation. They were, however, behaving as if “.” had been specified (ie. “@:.”, “.:.” or “/aaa/:.:/bbb/” for the previous example). This undocumented behavior is no longer supported. Other paths in the same path specification are unaffected.

3Delight for Maya

Added support for exporting polygon mesh sharp edges and creases as real creases when using the “Poly As Subd” mode in geo attribs. There are two new options for this in the same location as “Poly As Subd”. This lets a low resolution mesh rendered as a subdivision surface be very close in shape to the subdivided polygon mesh.
