Hi! Some updates in the development.
Since Unity 2018.3 is really near to be released we choose to postpone the 1.3 version until it release and included already many features only planed to 1.4 such nested prefabs and new group system. This is now how we plan to release next the future versions.

  • Support to new Unity’s Prefab System. Groups are using nested prefabs!
  • Rework in the Material System. Now much more streamlined workflow and added support to principled shaders. No custom node groups required anymore.
  • Colors are now exported as Gamma Corrected producing closer results.
  • Many Fixes and Bug Corrections.

  • Full Support to EEVEE materials
  • Collections support instead Groups. Include Nested Collections as Nested Prefabs

As promised B2U 1.3 is here with many improvements!

  • Support to Unity 2018.3 (older versions was deprecated due many changes in Unity)

We found a showstopper bug in group data export. The v1.31 is a hotfix for that and is already released in Blendermarket. for those that purchase in Unity Store it’s under review and will be available soon.
