I'm using 3D Studio Max 2012. I've got a simple mesh and several other polygons and I want to group everything all together. But the option is greyed out, I can't actually select 'Group' under the menus.

I've tried exploding and collapsing the mesh but nothing seems to work.

How can I group them together, what things can I do to try to diagnose the problem?

EDIT: My object hierarchy looks weird:

scene root:
 . object 1
 - object 2 ... 99

I fixed the problem by moving everything under model. I guess everything needs to be under the same parent to group. – rlb.usa Sep 28 '11 at 9:21
You should post that as an answer so that the question can be marked as accepted by the system. – Tetrad Sep 28 '11 at 14:39
I couldn't post a reply to the answer at the time, the option wasn't available. – rlb.usa Sep 28 '11 at 23:51

select the objects you want to group. hit the unlink selection button (the broken chain icon) And than you can group.

3D Studio Max has issues when trying to group objects with different parents. In a way, it makes sense that objects with different hierarchies shouldn't be allowed to group together. However, from an unwary user's perspective, this is a frustrating, wtf, kind of "gotcha".

To fix it, simply correct the hierarchy.

Another workaround if you are in a rush, just highlight all the objects and create a 'selection set' this helps enough for me. Of course it depends what you intend to use them for once they are grouped...
