Default Paper2D comes with apply default paper2D action, but we can take it a step further and apply our own parameter to our asset.

• Create a Tools folder in Content
• Right click → Edit Utility Blueprint

• Select Asset Action Utilitiles
  • Name to EUB_ApplyDefault2DParams

• Create Function ApplyDefault2DParams

• Get Selected Assets → For each loop → Cast Texture2D → Set necessary parameter
  • Need to use Set Editor Property for one of the property.
    • Property Name: Filter
    • Property Value: Nearest
    • Change Notify Mode: Always

<aside> ⚠️

You must use Set Editor Property for at least one of the property! This is because UE does not mark the asset “Dirty” when using the normal setter and will end up not being able to save the asset. Make sure you set Change Notify Mode to Always since we are only calling this on a single property and we might be setting the same value.

Additionally I think chaining it from the setter is cleaner so you don’t need to specify 0 to represent Nearest.

</aside>

• Only show this for Texture2D (This is for 5.2+, you will need to override Supported Class for older version)
  • Add Texture to Class Defaults → Supported Class

• Right click on Texture
  • Scripted Asset Actions → Apply Default 2D Params

You can create additional functions to set different param if needed.
