V-ray 5 for houdini won't render when Arnold is loaded

[elrachyd]

Hi
V-ray 5 for houdini won't render when Arnold is loaded, no error in console!
if I rename Arnold.json file to something like Arnold.json____ or move it completely from packages folder then, V-ray 5 render fine without any problem!
here is my json file for V-ray & Arnold respectively
{
"env": [
{ "INSTALL_ROOT" : "C:\Vray" },

{ "VRAY_APPSDK" : "${INSTALL_ROOT}/appsdk" },
{ "VRAY_OSL_PATH" : "${INSTALL_ROOT}/appsdk/bin" },
{ "VRAY_UI_DS_PATH" : "${INSTALL_ROOT}/ui" },
{ "VFH_HOME" : "${INSTALL_ROOT}/vfh_home" },

{ "PYTHONPATH" : "${INSTALL_ROOT}/appsdk/python27" },

{ "PATH" : [
"${HFS}/bin;${VRAY_APPSDK}/bin",
"${VFH_HOME}/bin"
] },

{ "HOUDINI13_VOLUME_COMPATIBILITY" : 1 },
{ "HDF5_DISABLE_VERSION_CHECK" : 1 },
{ "HOUDINI_GALLERY_PATH": "${HOUDINI_GALLERY_PATH}; ${VFH_HOME}/gallery" },
{ "VFH_ASSET_PATH" : "C:\Vray\V-Ray Material Library/assets" }
],
"path" : [
"${VFH_HOME}"
]
}

and Arnold
{
"env":[
{"PATH": "$PATH;C:/Solidangle/HtoA/htoa-5.5.0.2_r1582e12_houdini-${HOUDINI_VERSION}/scripts/bin"},
{"HOUDINI_PATH": "C:/Solidangle/HtoA/htoa-5.5.0.2_r1582e12_houdini-${HOUDINI_VERSION}"},
{"ARNOLD_PLUGIN_PATH": "C:/Solidangle/Arnold_Shader/lentil/bin;C:/Solidangle/Arnold_Shader/Osl/bin;C:/Solidangle/Arnold_Shader/LightFilter/bin"}
]
}

any suggestion to solve this issue?
Thanks

I'm running both from the houdini.env file no issues

Is it because the arnold json wipes out HOUDINI_PATH instead of appending it?

Have an issue to.
I use Json for Vray 5 and env for Redshift, it's work. If i add arnold with env, Vray disapear, if i use json to add Arnold Arnold isn't appear.
If i use Json for Vray 5 AND Redshift, Vray crash when rendering.

I have success befor to mak work VRAY Redshift and Arnold together. But not anymore.

Pop!OS 20.10 // Houdini 18.5.408 // Vray Redshift and Arnold all lastest realease ( or nightlies )

I solved the problem by changing Arnold.json file
from this:
{
"env":[
{"PATH": "$PATH;C:/Solidangle/HtoA/htoa-5.5.0.2_r1582e12_houdini-${HOUDINI_VERSION}/scripts/bin"},
{"HOUDINI_PATH": "C:/Solidangle/HtoA/htoa-5.5.0.2_r1582e12_houdini-${HOUDINI_VERSION}"},
{"ARNOLD_PLUGIN_PATH": "C:/Solidangle/Arnold_Shader/lentil/bin;C:/Solidangle/Arnold_Shader/Osl/bin;C:/Solidangle/Arnold_Shader/LightFilter/bin"}
]
}

to this:

{
"env": [
{
"PATH": "C:/Solidangle/HtoA/htoa-5.5.0.2_r1582e12_houdini-18.5.408/scripts/bin",
"method": "append"
},
{
"ARNOLD_PLUGIN_PATH":"C:/Solidangle/Arnold_Shader/lentil/bin;C:/Solidangle/Arnold_Shader/Osl/bin;C:/Solidangle/Arnold_Shader/LightFilter/bin",

},
],
"path": "C:/Solidangle/HtoA/htoa-5.5.0.2_r1582e12_houdini-18.5.408"
}

Then renaming Arnold.json to Solidangle.json to make it load last
and Vray.json to Avray.json to make it load first
and move Redshift.json to houdini.env.file

houdini.env

REDSHIFT_COREDATAPATH = "C:/ProgramData/Redshift"
PATH = "$REDSHIFT_COREDATAPATH/bin;$PATH"
HOUDINI_PATH = "$REDSHIFT_COREDATAPATH/Plugins/Houdini/${HOUDINI_VERSION};&"
REDSHIFT_RV_ALWAYSONTOP = "0"
REDSHIFT_RV_OPEN_ONLY = "1"
REDSHIFT_DEFAULT_SHADER_COLOR = "0.3 0.3 0.3"
REDSHIFT_AUTOSPAREPARAMS = "0"
PXR_PLUGINPATH_NAME = "C:/ProgramData/Redshift/Plugins/Solaris/${HOUDINI_VERSION};&"
