Vfr 3 can't 100% compatible Vfr 2 material, when I read the old file?

[pun1407]

Why 3.6 can't do it? How can I use my old library and old file, when I can't to use Vray 2? I need to make all project again?

Hi,

Apologies for the delayed response!

Kindly note that older binary .vismat files are not compatible. Newer xml vismat files, however, are compatible and so are the .vrmat files. When a scene saved with V-Ray 2 is loaded in Rhino (using V-Ray 3), an upgrade script will go through all the scene assets and features to account for incompatibilities. All lights, materials, and special objects will be upgraded from groups to a new component definition system.

Could you please share the project with us so we can investigate in detail and advise accordingly? If this is alright, please send us an archived copy (V-Ray > Pack Project) to support@chaosgroup.com
