I noticed this has been asked many times before, but there doesn't seem to be a clear answer. What are the performance impacts of blend shapes? And are there any specific things to avoid while using them? In particular, this post caught my attention: https://answers.unity.com/questions/1578678/performance-impact-of-blend-shapes.html It would be nice to know before creating any model's and bench-marking them only to find blend shapes are unusable for a certain purpose. I'm curious so I guess I'll create a poll too, although I expect this post won't get much attention judging by all the other posts already made about this topic.
