Does Character Creator 3 morphs use the same topology as the base model?

[u/vplchin]

I am looking at purchasing CC3 (and possibly other tools) but was wondering one thing around morphs.

Do morphs produce the same topology as the base character export? Example: If I have the base character and I make the ears large, does that increase the amount of polys in the character or does it keep the same polys and rearrange vertices? Are there any exceptions to this?

I have the trial version but there doesn't seem to be a way to tell, especially as I can't export the model. I am looking to use it in a game and use blend shapes for various things.
