3ds Max, vray 5 - Materials & Textures gone crazy

Hi, all.

I noticed it since the last october update that materials and textures goin crazy, when I export files with datasmith. In Unreal glossiness and alpha maps are normal maps, mip map is set to sharpen5 (not the best) and all textures are srgb (exept normal maps, hurray). UV tile settings are sometimes there sometimes not… Tested it in Unreal 4.26 and 4.27.
So my question is, is it me or the datasmith plugin.

Regards, urig
