In order to load these modules, a folder needs to be set up before starting 3ds Max. In some cases, when using MDL files exported from Substance Designer, V-Ray may fail to load some modules. Importing MDL Files from Substance Designer VRAY_MDL_PATH_3DSMAX2018_圆4=C:\Program Files\Chaos Group\V-Ray\3dsmax 2018 for 圆4\mdl %PROGRAMDATA%\NVIDIA Corporation\mdl %USERPROFILE%\Documents\mdl Where yy is the version of Max installed. VRAY_MDL_PATH_3DSMAX20yy_圆4=%PROGRAMDATA%\NVIDIA Corporation\mdl %USERPROFILE%\Documents\mdl An alternative way to add them to the system paths is to append them to the V-Ray environment variable that specifies default location for MDL modules: In order for the MDL Material to correctly load NVIDIA vMaterials, the following two paths should be present in the MDL Search paths lists: %PROGRAMDATA%\NVIDIA Corporation\mdl %USERPROFILE%\Documents\mdl By default, on vMaterials installation they are set in the environment variables MDL_SYSTEM_PATH and MDL_USER_PATH which is the proper workflow. Removes a path from the Additional paths list.Ĭlears all paths from the Additional paths list. Adds a path to the Additional paths list.
