Reflection glosiness under reflection

Hi, why does all my materials get set to 0,99 under ref.glos under reflection? Very annoying! Please help. Have latest version. Thanks!

Hi, Thanks for looking into it. It seems like this happens in some scenes and almost randomly. Maybe it's a problem related to multi/sub. I have to send you a copy of an earlier scene I had som problems with. I have to send it by WeTransfer because of size. Thanks!

Hi again, now the reflections get set to 0,7. Any solution?

Hi Jerome, It seems like there might be a problem with multisub. All the materials ref. glos. equals the first id material in the multisubmat. When I change the first the rest will change as well to the same number when I render. Any suggestions?
