Calculating VRayProxy bounding box in MayaBatch

[TomMelson]

Hi, I'm calculating the bounding box of VRay proxies as part of a thumbnail creation process. This works fine in Maya as long as the geo is displayed, using:
cmds.polyEvaluate(meshNode, boundingBox=True)
But when the process runs in Maya batch, the bounding box returns as empty. I guess this is because in Maya batch it dosn't generate the Maya geo or something?

Does anyone know a better way of getting the bounding box, maybe directly from the proxy or something?

Thanks

Excuse the delayed answer. Indeed the geometry is not loaded for preview in Maya Batch, however, setting the proxy's 'Geometry to load' type to 'Maya mesh' should output correct bounding box coordinates.

Example script:

polyMesh = maya.cmds.vrayCreateProxy(node='mesh_vraymesh', existing=True, dir='E:\\Proxies\\3333.vrmesh', createProxyNode=True)

print polyMesh

cmds.setAttr("mesh_vraymesh_vraymesh.geomType", 3)

print cmds.polyEvaluate(polyMesh, b=True)

Hi Alexandar, sorry I've only just had the chance to test this out and indeed this solution works. thanks a lot!
