All you need is permission to USE the models.
As for not being compatible, no models will be directly compatible with the SH series.
However, when S3D has the ability to import export models and texture data via the collada format, then the ability to use such models becaomes available.
So I wouldn't shoot this idea down yet. Rather hold on to the info and you may find this becomaes useable in future versions of S3D.
