Thanks Will, if you have any tips from your experience I'm all ears.

Hi Keith, Will covered the points well, see also http://assets2.digitaltutors.com/pdf/QuadsTriangles.pdf for a nice summary. For me going into Unity the models will be triangulated so by keeping the whole baking pipeline as triangles avoids any issues with normals. As the animation isn't the deformation kind it doesn't make a difference.

Cheers
Andy
