Failed to load plugin 'hdCycles'

Cycles Development
#1

Was fallowing cycles/BUILDING.md at master · blender/cycles (github.com).

ERROR: Usdview encountered an error while updating selection.
Error in ‘pxrInternal_v0_22__pxrReserved__::PlugPlugin::_Load’ at line 258 in file E:\dp\Sft\3D\USD\pxr\base\plug\plugin.cpp : ‘Failed to load plugin ‘hdCycles’: ???
in ‘e:/dp/Sft/3D/Blender/Cycles/cycles/install/hydra/hdCycles.dll’’

Is that the complete error log, or is there any more detailed information? Does that dll file exist?

#3

That was the 1st error, the rest is basically the same, just when trying to render.

dsoError.c_str() was shown as ???, due to language issue?

  • The ??? should be “The specified module could not be found”.

Sure the DLL exists,

  • either in E:\dp\Sft\3D\USD_Build\plugin\usd,
  • or in PXR_PLUGINPATH_NAME which is cycles\install\hydra

The plugin name is shown:
Failed to load plugin ‘%s’
_name.c_str()

cycles\install\hydra

  • hdCycles\resources\plugInfo.json
  • hdCycles.dll
  • plugInfo.json

Cycles tells us to use PXR_PLUGINPATH_NAME=/install/hydra.
While hdTiny (really works) tells us to use the “resources” folder.

resources\plugInfo.json is also quite strange, …/hdCycles.dll needs to be …/…/hdCycles.dll?

#5

Was missing some paths for dependent DLLs, fixed.
