The glmBatchCrowdSimulationExporter commands batch exports Simulation Cache files, Renderer specific scene files (.ass, .vrscene, .rib, .mi...) or baked simulation FBX files which will be used to render a crowd simulation. In Batch mode, Golaem Crowd and Maya do not compute/update all their simulation nodes. Thus, to be able to export a crowd simulation in Maya batch it is required to enable the batch mode computation and explicitly update those nodes. To enable the batch mode, it is required to set the  environment variable GLMCROWD_BATCH_ENABLE to 1 (for more information about Environment Variables, check here). The command glmBatchCrowdSimulationExporter handles all those settings.

MEL Examples

// batch export Simulation Cache files only between frame 1 and 100
glmBatchCrowdSimulationExporter -startFrame 1 -endFrame 100 -crowdFieldNode "crowdField1" -exportFromCache 0  -scExpAttrs "particleId" -scExpName "testScene" -scExpOutDir "N:/tests/export"  -fbxExpEnabled 0  -ribExpEnabled 0  -mentalRayExpEnabled 0  -vrayExpEnabled 0  -arnExpEnabled 0;

Usage with Maya Batch

A MEL file usable by Maya Batch and calling this command can be created by the Simulation Exporter. Once created it can be called using the following system command:

pathToMaya\bin\maya.exe -batch -script "pathToMelScript/myCache.batch.mel" -log "pathToLog/batchRender.log"
