optimize: create multiple game objects with one texture atlas

Hi,

i just started with gamedraw. im using Unity 4.2 indy and the recent mxd suite (pro).

I want to create one atlas for several meshes but dont want to combine the meshes to one gameobject. After watching the optimization tutorial i tried several methods but it doesent work as i expected it.

The only workflow i came up with is:

- select the game objects > optimize combine (multiple materials)

- select the combined game objects > optimize combine > advanced

- it creates the UVs and the atlas but i then i have to manually set the atlas back to all the material slots.

- then i have to save the object with gamedraw (otherwise the uvs are all overlapping again when i open gamedraw modelling mode)

- then i have to use the saved object to detach all the single objects with gamedraw modelling

This results in separate objects with one texture atlas and one drawcall.

But this is very time consuming and buggy (there are several exceptions thrown all the way).

Is there an easier solution? 

Thanks,

Matthias
