It seems using a volumesamplefile VOP in an attributeVOP and pointing the geometry file to a SOP using something like op:/obj/myvolume/vdbfrompolygons works just fine to sample the volume. But when the same VOP is used inside a material it fails to sample the volume. It seems in the material context it will only sample the volume correctly if it is read from an actual file on disk.
Is this true? I thought the op:/ syntax should work almost anywhere ?
volesamplefile VOP and op:/ syntax fails in shader?

Mantra doesn't have access to houdini network, only to whatever geo is currently in ifd
You can use op: syntax to point to any SOP that has Render flag on whose Object is included in render
Typical workflow is to make such object not renderable, but still in Forced Objects, just to get it to .ifd
