|---|
The environment variable for RfH must be listed first in the houdini.env file. (Windows requires a semi-colon) For example: HOUDINI_PATH=$RFHTREE/3.7/19.0.383:& RenderMan for Houdini with Solaris requires an additional line in the configuration file to be able to render in-memory vdbs: RMAN_PROCEDURALPATH = $RFHTREE/3.7/19.0.383/openvdb:& RenderMan for Houdini on Windows requires an additional line in the configuration file: PATH=$RMANTREE\bin;& Additional instructions and details are found below in this document. |

For example on Linux, one would edit this file in: $HOME/houdini18houdini19.05/houdini.env:
| Code Block |
|---|
RMANTREE=/opt/pixar/RenderManProServer-2425.20 RFHTREE=/opt/pixar/RenderManForHoudini-2425.20 RMAN_PROCEDURALPATH=$RFHTREE/3.9/19.05.383569/openvdb:& HOUDINI_PATH=$RFHTREE/3.9/19.05.383569/:& |
On Windows with 18.0, one would edit the file in: \Users\myself\Documents\houdini18houdini19.05\houdini.env:
NOTE: Windows uses a semi-colon instead of a colon to separate the HOUDINI_PATH!
| Code Block |
|---|
RMANTREE="C:\Program Files\Pixar\RenderManProServer-2425.20" RFHTREE="C:\Program Files\Pixar\RenderManForHoudini-2425.20" RMAN_PROCEDURALPATH=$RFHTREE\3.9\19.05.383569\openvdb;& HOUDINI_PATH=$RFHTREE\3.9\19.05.383569;& PATH=$RMANTREE\bin;& |
Finally an example on OS-X with 18.0macOS, one would edit this in: /Users/myself/Library/Preferences/houdini/1819.05/houdini.env:
| Code Block |
|---|
RMANTREE=/Applications/Pixar/RenderManProServer-2425.20 RFHTREE=/Applications/Pixar/RenderManForHoudini-2425.20 RMAN_PROCEDURALPATH=$RFHTREE/3.9/19.05.383569/openvdb:& HOUDINI_PATH=$RFHTREE/3.9/19.05.383:&569:& |

Lama Parameter Name Changes
Some parameters on Lama nodes were changed in RenderMan 25. The parameters "color" and "normal" have been changed to be node-specific. For example, color is now diffuseColor on the LamaDiffuse node. This was done in preparation for making the nodes compatible with XPU in the future. For scenes with version of RfH older than 25, you need to run once manually top menu "RenderMan" > "Update Lama Nodes" if using a Houdini version older than H19.5.501 (it's automated otherwise). You will also need to update your custom locked HDAs manually.
