My imported decal textures has an unwanted white outline.

The texture looks fine before I import it.

But once in-game it now has a weird line that looks even more define when placed in the environment.

Not sure what’s forcing it in.

Try setting the X- and Y-axis Tiling Method to Clamp on the texture.

No luck. :-/

Changing filter to “Nearest” gets rid of the white line when looking at the texture directly, but not from the decal placed in-game.

As I zoom out the decal looks good. The close I get the more of the white line appears.

What are the settings you’ve modified for the texture and/or material? I just tried importing a random .png as a texture, created a material from it, and plugged the RGB into base color and Alpha channel into Opacity. Then set the Material Domain to Deferred Decal and added it as the Decal Material to a DecalActor. And not seeing any white lines.

EDIT: If I change the Blend Mode (in the Material) to AlphaComposite, I see a white line around it. If yours is like that, try setting it to Translucent or Modulate - making sure the Material Domain is still Deferred Decal.

Still outline with Modulate or Translucent.

Here is the full texture I’m using (I have the same issue regardless of if it’s a white background or transparency around it).

OK… Extended the Texture Sample node in the material editor. Under MipValueMode I changed it to “absolute” from “none” and it’s working! Thanks for helping me!
