is_supported()

bool blender::io::usd::USDGenericMeshWriter::is_supported ( const HierarchyContext * context ) const

overrideprotectedvirtual

Returns true if the data to be written is actually supported. This would, for example, allow a hypothetical camera writer accept a perspective camera but reject an orthogonal one.

Returning false from a transform writer will prevent the object and all its descendants from being exported. Returning false from a data writer (object data, hair, or particles) will only prevent that data from being written (and thus cause the object to be exported as an Empty).

Reimplemented from blender::io::usd::USDAbstractWriter.

Reimplemented in blender::io::usd::USDMetaballWriter.
