of course you have to adapt the paths to your file systems

i ended creating 2 json files one for arnold and one for renderman
arnold.json:
{
"env":[
{"PATH": "C:/Users/PATAR/htoa/htoa-5.6.3.0_ra766b1f_houdini-18.5.596.py3/htoa-5.6.3.0_ra766b1f_houdini-18.5.596.py3/scripts/bin"},
{"HOUDINI_PATH": "C:/Users/PATAR/htoa/htoa-5.6.3.0_ra766b1f_houdini-18.5.596.py3/htoa-5.6.3.0_ra766b1f_houdini-18.5.596.py3;&"},
]
}

renderman.json:
{
"env":[
{"RMANTREE" : "C:/Program Files/Pixar/RenderManProServer-24.1"},
{"RFHTREE" : "C:/Program Files/Pixar/RenderManForHoudini-24.1-py3"},
{"RMAN_PROCEDURALPATH" : "$RFHTREE/18.5.596/openvdb;&"},
{"HOUDINI_PATH" : "$RFHTREE/18.5.596;&"},
{"PATH" : "$RMANTREE/bin;&"}
]
}

and create 2 batch file to switch between render engine which rename the unused json file to txt and run houdini
renderman.bat:
@echo off
cd C:\Users\PATAR\Documents\houdini18.5\packages
if exist renderman.json (
echo file exists
) else (
echo renaming json file
ren renderman.txt renderman.json
if exist arnold.json (
ren arnold.json arnold.txt
)
)
"C:\Program Files\Side Effects Software\Houdini 18.5.596\bin\houdini.exe"

and arnold.bat:
@echo off
cd C:\Users\PATAR\Documents\houdini18.5\packages
if exist arnold.json (
echo file exists
) else (
echo renaming json file
ren arnold.txt arnold.json
if exist renderman.json (
ren renderman.json renderman.txt
)
)
"C:\Program Files\Side Effects Software\Houdini 18.5.596\bin\houdini.exe"

for me this solution works well better than using mutiple version of houdini

ill put it here just in case someone running into the same problem

do u happen to know how to install renderman with arnold? i installed it fine until i need to add spare parameters to objects...
it requires the renderman parameters declared first ( or else the spare parameters are empty) but if i do that everytimes i create objects houdini creates error ( when it tries to add custom parameters for arnold, and this seems to be the default behavior if u installed arnold) any sugestion?
thanks in advance

Help! HDA parameters not showing in unreal
1. i used unreal engine 4.25.4 (i know the plugins compatibility is with 4.25.0, but i can't find ways to install 4.25.0 anymore its not listed in the launceher anymore)
2 i use houdini (18.5.462, 18.5.486 both python 2 or 3 version , which version should i use?)
3 also tried to download the plugins from the github for ue 4.25 and houdini 4.62)
4 also manually copied it in the plugins>runtime directory
5 plugins is ready and loaded, can import hda and instantiate it. it also works too "if" there are no promoted parameter,.
