Description

The cache for images inside of an invalidation box needs to be invalidated at least once before changing a parameter that is applied to the material of the image will have an effect.

Steps to Reproduce
  1. Download the attached project
  2. Open the project
  3. Play in PIE
  4. Press the 'k' key (this is used to change the parameter for the material that is applied to the images)
  5. Press the 'j' key to invalidate the cache for the images
  6. Press 'k'

Result: The Color of the images do not change until the cache for the images have been invalidated
Expected: The color of the images would change when changing the parameter for the material that is applied to the images without a need to invalidate the cache
