I have a character with a few hundred morphs (blendshapes). This character also has clothes that contain a similar number of morphs to ensure they fit.
If I export the .fbx model without any morphs (blendshapes) then the file size is around half a megabyte. If I include all the blendshapes the file size goes up to over 25 Megabytes.
I really like having all those blendshapes for altering my character appearance. However, I wonder how much it impacts the games performance.
Will it ‘just’ impact on the size of the final executable and not have a significant performance hit or will all that extra data just being there and being loaded for each instance of a character significantly affect the performance?
Is it worth-while going through all the morphs to work out which ones I can do without?
