With that changed in the USD file (simply multiplied the values by 0.01 and saved again), DoF starts behaving correctly.īased on a comment in the relevant exporter code ( usd_writer_ Since the scene unit is set to meters (“metersPerUnit” is 1), rather than the USD default of centimeters, these should be in decimeters instead. Is there a plan for some validation tests against publicly available USD scenes likeĪLab, Moana, The DoF issue is also happening because the Blender USD exporter currently always writes out “focalLength”, “horizontalAperture” and “verticalAperture” in millimeters, but the spec declares those as “tenths of a scene unit”. I will post some renderings and comparisons to Karma later. *when there is no envmap there seems to be always a white/gray constant background light *the environment map is wrongly oriented (the horizon is rotated by 90 deg) Is there a reason why _stageMetersPerUnit is not 1.0 or why the scene scale needs to be adjusted in the first place? This breaks lighting since the scene is rescaled but not the light parameters (which are usually in radiance). _stageMetersPerUnit is set to 0.01 by default.the when building against plain USD the minimal supported version is 21.11 since this adds the -use-cxx11-abi 0 option.the minimum USD version is 21.03 (this introduces HdMaterialNetwork2). hdCycles does not build with Houdini 18.5.* (i.e., USD v20.08).I experimented with the Hydra delegate today and got it running on some test scenes. target install -config Cleanįirst of all good job on updating the build system for the delegate. target install -config DebugĬd %BUILD_DIR%
