For various reasons I don’t want to try Unity 3.1 just yet, but I’m just wondering - if you have a scene with several objects that reference the same mesh and you apply lightmapping with Beast, are all the objects then assigned their own unique copy of the mesh with its own UV map?. And as a result the final distributable package containing several meshes as opposed to a single mesh?.
No, all those objects will still share one mesh. What will be different per object instance is lightmap atlas info (lightmap index, tiling and offset), which is just one int and four floats.
That’s great. Thanks for the info, Robert!
