UE4 dynamic wrinkle map blendshape

ArcaneLeo

so, after i read about uncharted 4 tech, i was really interest in achieve this kind of effect

i want to make my character blendshape react automaticaly with wrinkle map, i see this kind of effect was on nathan drake expression, hand and even cloth
i want to achieve exact same result with UE4, without plugin of course

im doesn't know c++ in ue4 , maybe in the future i should learn c++ ,
, maybe i can learn Blueprint a bit
in cryengine there a slot to insert your wrinkle map, but in UE4, you should create the system from scratch 

there some tutorial, but it pretty manual, like you control the wrinkle manually from scratch,
like you animate the wrinkle manual 

but what i want is the wrinkle follow the expression, like if BrowUp then the forehead wrinkle show
and if BrowDown then forehead wrinkle dissapear

from what i learn, you should make an overall wrinkle, and mask it into pieces,
and what i want to learn are how to tell the wrinkle to show when the expression are triggered

its very technical but if someone have a knowledge of this thing, it will be awesome to share in this thread

Hyperloop

I believe they have added bone drivers...you could use bone rotation/position to drive wrinkle map opacity through the use of material parameter collections.

really?? using bone instead of blendshape??
i have seen some videos done it , majority of it using blendshape,
but how can it achieve by using blendshape
