Overview
...
This is a command-line utility that can be used to convert .ply, .obj, .bin, .geo, .bgeo, .hclassic, .bhclassic, .abc and .vrscene files to .vrmesh files for for rendering with V-Ray through V-Ray's Proxy Objects.

UsageUsing the following command, converts the |

given .ply or .obj file and writes it to the given .vrmesh |
...
file. Note that you must specify the file extension |

ArgumentsinputFile – Specifies the .ply .obj .bin .geo (.hclassic) or .bgeo (.bhclassic) .abc .prt or .vrscene input file name. The string may include wildcards. outputFile – Specifies .vrmesh file output name (extension must be specified). This string may not include wildcards. If this is not specified, then the output is a file with the same name |
...
but with the .vrmesh extension. If multiple input files are specified and <outputFile> is missing, then each input file will be written to a separate .vrmesh file. If multiple input files are specified and <outputFile> is also specified, all input files are sorted in lexical order and concatenated into one animated .vrmesh file. Options-verboseLevel – An integer value to determine the verbosity of the output. (0 - no output; 1 - errors only; 2 - errors and warnings; 3 - errors, warnings, and informational messages; 4 - all output). The default is 3. -append – Appends the information as a new frame to the .vrmesh file. -smoothNormals – Generates smooth vertex normals. Only valid for .obj and .geo files; always enabled for .bin files. -smoothAngle – A floating point number that specifies the angle (in degrees) used to distinguish if the normals should be smoothed or not. If present, it automatically enables the -smoothNormals flag. -flipNormals – Reverses the face/vertex normals. Only valid for .obj, .geo, .bin, and .abc files. -flipVertexNormals – Reverses the vertex normals. Only valid for .obj, .geo, .bin and .abc files. -flipFaceNormals – Reverses the face normals. Only valid for .obj, .geo, .bin, and .abc files. -flipYZ – Swap y/z axes. Needed for some programs, i.e., Poser, ZBrush. Valid for .ply, .obj, .geo, and .bin files. -flipYPosZ – Same as -flipYZ but does not reverse the sign of the z coordinate. -flipXPosZ – Same as -flipYPosZ but swaps x/z axes. -mapChannel <chanIndex> – Stores the UVW coordinates to the specified mapping channel (default is 1). Only valid for .obj and .geo files. When exporting a mesh that will be used in Maya, currently, this must be set to 0, or the textures on the mesh will not render properly. -disableColorSetPacking – Only valid for .geo and .bgeo files; disables the packing of float1 and float2 attributes in vertex color sets. -materialIDs – Only valid for .geo and .bgeo files; assigns material IDs based on the primitive groups in the file. -materialIDs_splitGroups – Only valid for .geo and .bgeo files; assigns material IDs based on the primitive groups. These groups are split into different voxels/meshes and appear in visibility lists. -sortMaterialIDs – Only valid for .geo and .bgeo files; sorts the list of material IDs by the group name. Otherwise, they are in the same order as they appear in the .geo/.bgeo file. -fps <fpsValue> – A floating-point number that specifies the frames per second at which a .geo or .bin file is exported |
...
so that vertex velocities can be scaled accordingly. The default is 24.0. -previewFaces <numFaces> – Specifies the maximum number of faces in the .vrmesh preview information. |
...
The default is 9973 faces. -previewType <type> – Specifies the method used to generate a preview. clustering – Works very fast |
...
but is less accurate. -facesPerVoxel <numFaces> – Specifies the maximum number of faces per voxel in the resulting .vrmesh file. |
...
The default is 10000 faces. -previewHairs <numHairs> – Specifies the maximum number of hairs in the .vrmesh preview information. |
...
The default is 500 hairs. -segmentsPerVoxel <numSegments> – Specifies maximum segments per voxel in the resulting .vrmesh file. |
...
The default is 64000 hairs. -hairWidthMultiplier <multiplier> – Specifies the multiplier to scale hair widths in the resulting .vrmesh file. |
...
The default is 1.0. -previewParticles <numParticles> – Specifies the maximum number of particles in the .vrmesh preview information. |
...
The default is 20000 particles. -particlesPerVoxel <numParticles> – Specifies maximum particles per voxel in the resulting .vrmesh file. |
...
The default is 64000 particles. -particleWidthMultiplier <multiplier> – Specifies the multiplier to scale particles in the resulting .vrmesh file. |
...
The default is 1.0. -mergeVoxels – Merge objects before voxelization to reduce overlapping voxels -velocityAttrName <name> – Specifies the name of the point attribute |
...
that should be used to generate the velocity channel. By default, the v attribute is used. -pointSize – If specified, turns on point cloud generation and specifies the smallest size of the points. |
...
The default is 0.0 (point cloud generation is disabled). -velocityOffset <offset> – Specifies that the starting position should be offset by a fraction of the velocity channel, e.g., -0.25. Only valid for .geo, .bgeo, and .bin files. -mergeFiles – Merges all input files into one .vrmesh file. Input files are specified using wildcard. -mergeShaders – When merging files using -mergeFiles, this option merges all shaders with the same name into one shader. When merging .obj files, |
...
the first found .mtl file in the directory is parsed to get the ordering of the materials. Alembic subdivision specific-subdivideAllMeshes – Subdivides all alembic polygonal meshes, not only subdivision objects. -subdivisionLevel – Alembic subdivision level. -subdivideUVs <value> – Specifies the subdivision of the mapping channels. Value 0 to skip map channel subdivision and 1 to apply it. -preserveGeomBorders – Skips the subdivision for all geometry borders. -preserveMapBordersMode <mode> – Preserves map borders mode. Mode "none" to subdivide all map borders. *.vrscene specific-vrsceneList – Shows a list of available Nodes in the .vrscene file. -vrsceneNodeName <name> – Node name inside the .vrscene file. Must be specified! -vrsceneApplyTm – Applies Node transform matrix to the mesh. -vrsceneVelocity – Generates velocity channel (used for motion blur). -vrsceneFrames start-end – Exports animation range. -vrsceneWholeScene – Generates a proxy for all vrscene's geometric objects. Generic-info – Shows information about the specified .vrmesh file. -perObject – Prints additional information for each object in the file. Requires the -info flag. -frame <frameIndex> – Exports a particular frame from the specified file. Combined with -info option, it shows information about the specified frame from the .vrmesh file. Indices are 0-based. If this option is |
...
not specified, information is printed for each frame in the file. -oneFramePerFile – Exports each frame in a separate file. -padding <padding> – Frame padding number between 1 and 10. Default is 4.
