The conflict is only with Renderman and 3Delight
MOPS and others work fine!
here is MOPS.json

{
"env":[
{"MOPS":"C:/Users/rachid/Documents/houdini18.0/External/MOPS"},
{"PATH":"$MOPS"},
{"HOUDINI_OTLSCAN_PATH": "$MOPS/otls;@/otls"},
{"HOUDINI_TOOLBAR_PATH": "$MOPS/toolbar;@/toolbar"},
{"HOUDINI_SCRIPT_PATH": "$MOPS/scripts;@/scripts"}
]
}

Mine is not the latest right now, but I tried them on the 'latest' and correct version for Houdini.

And it works on my another PC with the same system and plugin version. Even both these PC can run it well on Cinema 4D.

Yes, that's because you have other renderer like Renderman, you have to make a json file for each renderer (Arnold, Renderman, Redshift etc..) avoid houdini .env file.
and when you want to use Arnold, simply rename others json file or by putting a simple dash for each json file

Here is my . json file for both Arnold & Renderman
You have to put all your json file in packages folder (C:\Users\YOUR_NAME\Documents\houdini18.0)

#### Renderman
{
"env":[
{"RMANTREE" : "C:/Program Files/Pixar/RenderManProServer-23.2"},
{"RFHTREE" : "C:/Program Files/Pixar/RenderManForHoudini-23.2"},
{"RMAN_PROCEDURALPATH" : "$RFHTREE/18.0/openvdb;&"},
{"HOUDINI_PATH" : "$RFHTREE/18.0;&"},
{"PATH" : "$RMANTREE/bin;&"}
]
}


##### Arnold
{
"env":[
{"PATH": "$PATH;C:/Users/rachid/htoa/htoa-5.1.1_r126b954_houdini-18.0.391/htoa-5.1.1_r126b954_houdini-${HOUDINI_VERSION}/scripts/bin"},
{"HOUDINI_PATH": "C:/Users/rachid/htoa/htoa-5.1.1_r126b954_houdini-18.0.391/htoa-5.1.1_r126b954_houdini-${HOUDINI_VERSION};&"},
]
}

Thanks! But sorry for my stupid head....you mean I need to create couple json files in the packages folder under (C:\Users\YOUR_NAME\Documents\houdini18.0) with same name(rename the others which does not be used to avoid conflict)? But what name should I make it? And how I can let Houdini to find it? Do I need to modify any pref file manually, include .env file?

Thanks Rahid!!! It works finally!!! I just renamed the MOPS.json and didnot do anything!! I think the conflict is the reason!! But as I saw your folder that there are lots of different renderer or toolkit json files, how you can use them together, like if you need MOPS and render by Arnold?

I used to have this issue. You can use Houdini.env but you have to be careful about including "&" in you path.


Go the the Houdini-specific gotchas on this page.
