I can confirm that both my very basic test cube (DAE) and the Nadeo Valley Car
(DAE) don't work any more with the latest version of the importer. Both still work with the version before.
Also I tested that Nadeo didn't secretly add FBX support for car models.
The other thing I heavily dislike with the importer is that with every new update since MP3 the Importer finds new secret reasons to just "stop working". No error logs, no error messages, no hints at all. Blender FBX is affected with models working on the importer before since 2014-07-23, since 2014-09-10 we have even with 3DSmax models the same story.
To be very clear: I'm just talking about models which were and still are working with the version before.
My guess is that one of the things not mentioned in the so-called ChangeLog affects also textures.
A comment by a developer would be really
