I-m trying to make eyes blinking randomly inside material editor.
Right now I have no idea how to do that. If anyone knows how to, please share

Should be easy, except the random part…

  1. Mask your eyes out in the texture, so you have a channel with just the eyes.
  2. Multiply that channel with either 1 or 0.
  3. Make that 0 or 1 value a parameter
  • randomness need to be create outside the material editor
  1. Create a na ctor blueprint
  2. Create a dunamic material instance based on your material
  3. Create a function that toggls the material parameter between 0 and 1
  4. Add a delay node and loop it…
