I'm trying to load what appears to be an older sample scene (apparently created circa 1997) and during the loading process I get "No Plugin of type DisplacementHandler with name Deform::Pole found. Would you like to load it from disk?"

If I answer yes and go searching for it, the best I can find is in plugins/animate/deformer.p which has a Deform: pole (note only one ':'). However, this doesn't seem to satisfy the line from the .lws file,

Plugin DisplacementHandler 1 Deform::Pole

Is the above just and old syntax that I can edit with a text editor to get it to find the right plugin?
