I have 1x1 eyes on my skin and I did as I was supposed to for the type of eyes my skin has by adding the extra bit in the skin texture for the eyelids, I uploaded the skin to minecraft.net and I made sure all the mods I needed were up to date for the game version I am using and I had the issue with big black eyes but I followed the fix for that which fixed that, but my characters eyes are still not blinking.

Having a similar issue with 1x2. Skin was modified correctly as far as I can tell, but still no blinking. Would love feedback if I did this wrong. Thanks!

Are you using the Expressive Version or the Eyeless Version? I think maybe you are using a version of the mod that doesnt includes the eyes

When switching to my 2x3 skin it blinks and works properly, but when I use my properly configured 1x2 skin it does not work. I'm fairly certain it may be an issue with eye types that can only blink.

With transparency I can see the eyelids properly positioned but they are behind the eyes and never blink.
