(need advice) Best way to boost performance for mobile

Wow, there’s a ton of great info in this thread… thanks everyone for sharing! I will definitely be referring to this thread as I develop my own mobile game. I’m currently optimizing my character’s morph targets, and was wondering if unused/inactive morphs present in the character’s data will slowdown gameplay performance on mobile? Only the “blink” morph would get called 90% of the time. I’m also wondering if there’s any performance benefit to having the “blink” action contained INSIDE the idle cycle / walk cycle, rather than calling it separately through Blueprint randomly. Thanks for any tips on this. That is greatly appreciated!
