HdMoonRay Houdini Integration
After setting up the hydra delegate the UsdPreviewSurface and associated nodes will be renderable. To use the more advanced Moonray materials and maps, first clone the moonray_dcc_plugins repo. Include the folders inside of the repo’s houdini folder into your HOUDINI_PATH either by copying them into a folder already sourced or adding them to the HOUDINI_PATH environment variable.
Add the folder to your HOUDINI_PATH:
or copy the folders to your local houdini install:
cp -r $REL/plugin/houdini/* ~/houdini19.5/
You will find all Moonray related Materials and Maps available in the Mat context.
Connect Materials to the Collect node. Connect Maps to materials.
Lights have a Moonray tab with Moonray specific attributes.
You will find a Moonray tab with render settings specific to Moonray.
Geometry setting such as mesh_resolution can be set using a LOP wrangle node.
