I've updated the plugins to the latest version 3.08.1 but it still give me the same problem.
I created few scene tabs as instructed and assigned materials to objects. When I reopen my file, some of the materials were saved but some were not.
Some object even lost its 'material out' link. I've to reassign the materials to the objects several times again and again to the same scene of job.
Hope you can help to solve this problem.
Thanks
Kenji
