I have recently spent some time recreating almost all of the Photoshop Adjustments in the Unreal Engine Material Editor. You can find a marketplace link to my work here: Elias Wick - Adjustments in Materials - UE Marketplace
Adjustments is a collection of 14 unique material functions that can be used to adjust textures, materials and post process effects in Unreal Engine. Created with the professional artist in mind, these material functions can be used to add subtle improvements to your work or even create something completely new!
The Adjustments collection have been inspired by popular image-editing software, in order to help you achieve similar results in a more direct and efficient approach.
With the included showcase video and expansive showcase level, you can get started immediately with exploring the power of your new adjustments.
