When using the free edition of Unity 3D there are no dynamic shadows available and so you can create light maps in external 3D software such as Maya or 3DS Max.
When following the video guide I get the following error when setting up the export list, to be lightmapped in 3ds max. This error persists even when I return to 3ds max and check that the Unwrap UVW has normals checked.....
Hopefully I will sort this out and post the solution shortly.
Simple Primatives with no materials applied. When importing into unity and the setting export list for external light mapping the box is OK and will export but the sphere will not.
A slightly more complicated model again with no materials applied.
