For a list of all available arguments, run the command with the -help flag in the Maya Script Editor: vrayCreateProxy -help. |
Syntax
...
The various options are described below:
| Option | Description |
|---|---|
| -createProxyNode | After successful export, replaces the original geometry with proxy nodes. Can also be used along with the -existing option to load an existing proxy file. |
| -dir | Specifies the path where the .vrmesh file(s) will be created. |
| -existing | Uses existing vrmesh file instead of creating a new one. |
| -node | The name for the new proxy node when -createProxyNode is specified, and a single proxy is created. |
| -animStart | Override start frame when importing a sequence of files with <frame> filename tag. |
| -animLength | Override end frame when importing a sequence of files with <frame> filename tag. |
| -objectPath | Starting path in the Alembic object hierarchy when importing .abc files |
| -geomToLoad | Type of geometry to load:4 1- None 2 - Bounding Box 3 - Preview
4 - Full geometry |
| -flipAxis | Transforms from Max to Maya coordinate system. |
| -noMaterial | If specified, does not create a VRayMeshMaterial for the proxy. |
-vrayImportProxyRules | Imports material override rules (.xml) from a specified location. |
| -vrayExportProxyRules | Exports material override rules (.xml) to a specified location. |
| -newProxyNode | Uses the new VRayProxy node instead of the old VRayMesh. |
| -animOn | If specified, animated .vrmesh files are created. |
| -animType | If -animOn is specified, this option determines the animation interval to export: 1 - playback range 2 - animation range 3 - explicit frame range specified with -startFrame and -endFrame |
| -startFrame | Specifies the start animation frame when using explicit range. |
| -endFrame | Specifies the end animation frame when using explicit range. |
| -exportHierarchy | Exports full paths including transforms and groups instead of just shape names. |
| -exportType | Specifies the type of export: 1 - export all selected objects in a single .vrmesh file. 2 - export each selected object in a separate .vrmesh file. |
| -fname | Specifies the file name when exporting to multiple .vrmesh files. |
| -facesPerVoxel | An integer value that specifies the maximum number of faces that a voxel can hold. |
| -oneVoxelPerMesh | If specified, export each separate mesh to a single voxel. |
| -ignoreHiddenObjects | If specified, hidden objects are not exported. |
| -includeTransformation | If specified and exporting objects in separate files , bake the transformation of each object into the vertex positions in the resulting .vrmesh files. |
| -makeBackup | Create a backup .ma file containing just the exported objects. |
| -overwrite | If specified, any existing .vrmesh files will be overwritten; otherwise, an error will be printed. |
| -previewFaces | Specifies the number of faces in the viewport preview for the proxy object. |
| -previewType | The simplification method to use when generating a preview. Must be one of the following: "clustering" "edge_collapse" "face_sampling" "combined" |
| -lastSelectedAsPreview | Uses the last selected object as a preview mesh. |
| -pointSize | If higher than 0.0, create a point cloud representation of the mesh. The specified value is used as a minimum size of the disk samples. |
| -velocityIntervalEnd | A value between 0.0 and 1.0 with the time position within a frame for the ending vertex positions. |
| -velocityIntervalStart | A value between 0.0 and 1.0 with the time position within a frame for the initial vertex positions. |
| -velocityOn | If specified, vertex velocity is also exported. This enables motion blur and smooth interpolation of the resulting animated proxies. The time samples within a frame for computing the velocity are specified with the -velocityIntervalStart and -velocityIntervalEnd options. |
| -vertexColorsOn | If specified, vertex color sets are also exported. |

Export Mesh Example
The command operates on the current selection and has the following syntax, where curly braces {} denote a choice between several values separated by a pipe |, and options in brackets [] are optional:
...
| UI Text Box | ||
|---|---|---|
| ||
Note that $filename has to include the correct extension of the file, that is .abc or .vrmesh. |
Import Mesh Example
.vrmesh example:
| Code Block |
|---|
vrayCreateProxy -node $nodename -existing -dir $path.vrmesh -createProxyNode |
alembic example:
| Code Block |
|---|
vrayCreateProxy -node $nodename -existing -dir $path.abc -createProxyNode |
...
This command creates a proxy node and points it to an existing file (.vrmesh or .abc). Please note that "$path.vrmesh/abc" is the full path of the file. $nodename is $nodename is the name of the node in the Maya scene.
Import/Export Material Rules Example
Import material rules example:
| Code Block |
|---|
vrayImportProxyRules "pSphere_vrayproxy" "D:/Maya/Proxy/test.xml"; |
Export material rules example:
| Code Block |
|---|
vrayExportProxyRules "pSphere_vrayproxy" "D:/Maya/Proxy/test.xml"; |
These commands are equivalent to the existing Import/Export material rules button (
), but allow for scripting.
