Also read the FAQ.

Please read the HOWTO on how to import scenes from the most common 3D applications before posting questions in the forum.

The Unify Home Page also has a tutorial on how to get alpha channels in Photoshop to play nice with Unity.

 

It would be nice if the FAQ included a little more detail.

If you naively transform (e.g. scale) a blender object and then import into Unity the scaling is lost; you can fix this in Blender, and it would be nice if this were explained in the FAQ/docs.

Similarly, someone asked a question about IK animation not importing from Maya into Unity which was solved by setting some option in a less than obvious (to me) preference dialog. This seems like something that ought to be in the FAQ/docs.

 

What we really need is a single, simple table which shows key functionality crossed with different apps and gets updated appropriately.

This would be extremely helpful in allowing users to pick a package that suits their needs, or tell at a glance what limitations a given workflow is likely to encounter.

E.g.

3D Packages
Maya 8 *
Maya 7
Cinema4D R10.x **
Cinema4D R9.x
Lightwave R9.x *
Lightwave R8.5
Lightwave R8
XSI 5 ***
XSI 4 ***
3DS Max 9 (FBX) ***
Blender **
Blender (Collada) **
...

* Intel Mac version announced, but no definite date
** Intel Mac version available
*** Widely used non-Macintosh 3D software
