I had a problem hiding a model from the blob finder by using the
blobfinder_return 0 as it's documented in the stage manual, after going
through the code i found out that it should be blob_return instead of
blobfinder_return. It happened to me with more that one parameter but i
can't remember but i decided to let you know in case anyone have the same
problem in the future.
