We are using Character Creator 4. We are exporting models with blend shapes and clothing to .FBX format, and importing to Unity. Unfortunately when built the models can be up to 80MB which is very large for our web application. We aren't using high numbers of poly's.

Is it possible to reduce the number of blend shapes exported to below 60?

have you converted the characters to the 'game base' version?  For a webgl or mobile app the full skeleton will be pretty heavy.

You can also 'optimize and decimate' the characters before outputting them. This would let you lower the poly count etc. Also when you export, are you using the instalod options to bake the texture atlas etc? 

Character Creator provides quite a few options for optimizing the characters...

not sure about restricting morph targets that are output though...
