  • Visual Studio 2015 redistributable: In Windows, we now require the VS 2015 redistributable to be installed in order to run Arnold. We expect most of our users to have it already, but if not the installer can be downloaded from the following link: https://www.microsoft.com/en-us/download/details.aspx?id=48145 (#4445)
  • Custom cameras: Custom cameras can now implement camera_reverse_ray to convert from camera space to raster space. This makes it possible for any custom camera to work as a dicing camera, support min_pixel_width, support accurate raster-space wireframe width, etc. (#4477)
  • procedural node: The procedural node now only supports loading .ass, .obj, .ply files. The dso parameter has been renamed to filename. options.procedural_searchpath is now only used for this node.
  • Deferred procedurals: Removed support for deferred procedurals. All procedurals are now loaded during scene initialization (right before rendering). Also, load_at_init, min and max parameters have been removed.
  • Gamma options removed:
    • Output drivers now take a color_space string attribute to specify which color space to use for rendered images. Built-in values are linear, sRGB and Rec709. The default value auto will use sRGB for 8 bit formats and linear otherwise. All driver_*.gamma have been removed.
    • image nodes now have an color_space attribute to specify which color space the texture is assumed to be in. Built-in values are linear, sRGB and Rec709. The default value auto will use sRGB for integer (8 or 16 bit) formats and linear otherwise. The attribute options.texture_gamma has been removed.
    • Legacy gamma related options in kick (-g/tg/sg/lg) have been removed. You can now set the output color space for a render with kick -ocs <string>.
  • Removed legacy pixel filters: The following pixel filters, which were rarely used, have been removed: catrom2d_filter, cook_filter, cone_filter, cubic_filter, disk_filter, video_filter.
  • Always use auto-bounds for volumes and implicits: Volume and implicit plugins already notify Arnold of the bounds around the data they provide. Users could previously override this with min and max parameters, but those have been removed for volume nodes and are unused for implicit plugins. All volume plugins will automatically have a bounds_slack parameter available to expand the natural bounding box around the data for purposes of adding positional noise in shaders, etc. Volume plugins are responsible for increasing their reported bounds by the bounds_slack amount. Also, the load_at_init parameter has been removed from both volume and implicit type nodes, as it had no effect in practice.
