Hi,
I have a Meta Human inside my project and now I want to change the width of the pupil (the black dot inside the eye). I want to change this inside a blueprint, how can I achieve this?
Thanks in advance!
Hello @Otthercreek,
There are some pupil morph targets set up in the face mesh, but it is very subtle, I found you can get more extreme results if you change parameters inside the eye material.
Be sure to set up the DynamicMaterialInstances in the Construction Script too. (There are a few set up for eyelashes, so just copy the format)
As an experiment I also recorded myself while figuring this out. Let me know what you think. (The mic sounds weird for the first minute because it was picking up my laptop fan, but I was able to quiet the fan)

Thanks for the solution!
This worked pretty well and straight forward. The recording of the solution was really nice!!

Huzzah, I was just notified that my video got 50 clicks. This was the first and last time that I made a video ‘in the line of duty’. I had aspirations to make many more.
My idea for that video was ‘I do not know the answer to this question, so let’s figure it out live’ - Maybe these days people just want to be delivered what they want to know in the form of a 10 second tiktok? 
I’m open to feedback, would love to hear what you liked about it or what you didnt.
