When I load the Crowd .vrscene in 3dsMax, the parameters of the node are not updated

What have I done wrong ?

To fill the node attributes, the VRayGolaem bridge uses the Golaem Crowd VRay Plugin. If that plugin can not be found, it means that the VRay environment variable used to specify Vray plugins location has not been set correctly and you should get the following message in the 3ds Max Listener :

VRayGolaem: Error loading .vrscene file "C:\maxExport\vray.crowdProxyVRayShape.vrscene". vray_glmCrowdVRayPlugin.dll plugin was not found in environment variable "VRAY4_FOR_3DSMAX2020_PLUGINS" (C:\Program Files\Chaos Group\V-Ray\3dsmax 2020 for x64/bin/plugins;).

A common mistake is to set environment variable VRAY4_FOR_3DSMAXXXXX_PLUGINS for the wrong version of 3ds Max (i.e. 2022 instead of 2020) or that the PATH environment variable contains an incompatible version of the Golaem V-Ray procedural. The value of an environment variable can be easily checked in 3ds Max using the following MaxScript command:

systemTools.getEnvVariable("myEnvVarName")

And here're the expected results when querying the value of the environment variables in 3ds Max:

systemTools.getEnvVariable("VRAY4_FOR_3DSMAX2020_PLUGINS")
"C:\Golaem\GolaemCrowd-8.2-Max2020\procedurals\vray\40;C:\Program Files\Chaos Group\V-Ray\3dsmax 2020 for x64/bin/plugins;"

systemTools.getEnvVariable("PATH")
"C:\Golaem\GolaemCrowd-8.2-Max2020\bin;[...];C:\Windows\system;"
