AMD Radeon ProRender delegate for USD (hdRpr)
This plugin allows fast GPU or CPU accelerated viewport rendering on all OpenCL 1.2 hardware for the open source USD and Hydra system
For more details on USD, please visit the web site here.
Building this plugin depends on three things:
1. An existing USD build / tree
As many USD users get the USD libraries from different places, or compile their own, we tried to keep this as flexible as possible. You can download USD to build yourself from GitHub
2. Radeon ProRender SDK
Contact AMD for access to ProRender SDK libraries
Build using cmake. Here are the necessary variables to set
USD_ROOT - set this to the USD installed dir
RPR_LOCATION - set this to the Radeon Pro Render directory with include and lib dirs
CMAKE_INSTALL_PREFIX - this is where the delegate will be installed, most likely you will set this to the same as USD_ROOT
(Variables below may be automatically detected and you can leave them as is)
BOOST_ROOT - These are necessary libraries to link the plugin. If you installed USD, you already have these. If you installed USD using the python build script they are the same as USD_ROOT
example cmake building:
mkdir build cd build cmake -DUSD_ROOT=/data/usd_build -DRPR_LOCATION=/data/RPR_SDK/RadeonProRender -DCMAKE_INSTALL_PREFIX=/data/usd_build .. make make install
Try it out
Set the environment variables specified by the script when it finishes and
usdview with a sample asset.
> usdview extras/usd/tutorials/convertingLayerFormats/Sphere.usda
And select RPR as the render delegate.
If you want the RPR menu added to USDView (allows selecting device, and view mode), set the environment variable:
Where USD_ROOT is your USD install directory.
