Re: Vismat converter material usage issues Check what version of VfSU you’re using. All the converters were updated with the first SR, so the original release will not be able to read those material types. ---

I use the latest version. i downloaded all again and installed as new and did the conversion again. the problem remains - so what might it be? thanks
