Correct - it is the IOR. But the defaul the plugin uses in its conversion is 0. 0 however is the old indexing style of octane which has been replaced with a range of 1.0-8.0. The renderengine now treats0 as being an index 1.0 which is way too reflective. Together with a reflection value of 0.05 and rougness of 0.7 is renders like the first image.

In the second image I changed the index to 1.3 in the base of the sweater and it looks miuch better.
