This is my scripts for customizing The Foundry's Katana. Currently it mostly consists of args & lookfiles for shaders for Prman 16.5/17.0, Mtoa and SitoA shaders for Arnold 4.0.11.
(1) Set this env variable for your prman shaders
RMAN_SHADERPATH=$RMANTREE/lib/shaders
(2) Set this env variable for your arnold shaders for sitoa/mtoa
ARNOLD_SHADERLIB_PATH=/opt/arnold/sitoa/shaders:/opt/arnold/mtoa/shaders
(3) Installing Args files
copy all .args files into the folder $HOME/.katana/Args/
Prman 17.0 Args are for the default shaders included in the package. Under linux they are in these directories below. I copy them into my directory structure. I don't believe I have the rights to include them in this repository so you can simply copy them yourselves
/opt/pixar/RenderManProServer-17.0/lib/rsl/shaders /opt/pixar/RenderManProServer-17.0/lib/shaders /opt/pixar/RenderManProServer-17.0/lib/examples
/shaders
--/prman
----/16.5 < prman 16.5 shaders go here
------/Args < args for prman 16.5 shaders of the same name goes here
----/17.0 < prman 17.0 shaders go here
------/Args < args for prman 17 shaders of the same name goes here
--/Arnold < default shaders inside libai.so which is included with arnold
----/Args < args for default arnold shaders
----/mtoa < mtoa shaders
------/Args < mtoa args
----/sitoa < sitoa shaders
------/Args < sitoa args
--/shave < shave shaders
----/Args <shave args
The args are picked up from the following directories, in this order of precedence:
- Args subdirectory of the shader’s directory.
- ../Args directory relative to the shader’s directory.
- ../doc directory relative to the shader’s directory (Deprecated, for backwards compatibility)
- Args subdirectories of each directory in the KATANA_RESOURCES environment variable.
==========
To get these to work you need to put the shaders in your Arnold/Prman shader path. To get the Args for the default libai.so Arnold shader working I also had to put that path in my KATANA_RESOURCES. The example below is using BASH. You will need to make it slightly different if you want to use CSH or TCSH.
RMAN_SHADERPATH=$RMANTREE/lib/shaders
ARNOLD_SHADERLIB_PATH=/opt/arnold/sitoa:/opt/arnold/mtoa
KATANA_RESOURCES=$KATANA_HOME/plugins/Resources/Examples:$KATANA_HOME/plugins/Resources/PRMan17:$KATANA_HOME/plugins/Resources/Arnold4.0:/opt/arnold/mtoa/shaders:/opt/arnold/sito/shaders
**A quick note, prman shader path recursively looks down the folders and arnold does not. So that’s why I set prman to a single folder and had to set arnold for every folder.
