The 4 key should be pressed on the number row, not the keypad. If you are already doing that, check if any lock or setting is preventing those keys from being pressed.
My apologies for the misunderstanding. I thought you wanted to try it in the demo before buying.
To activate the two eyelids effect, enable it where the Create Widget node is called, which is in the level blueprint of the LVL_blink map.
You can adjust the eyelid shape inside the MI_Blink material instance. You only need to create a single eyelid and the logic will automatically duplicate it for the two eyelids option.
No problem. In the package the option is set directly in the setup because most players would never need to switch eyelids during gameplay. I only made it toggleable in the demo so you could preview both states easily.
