Fixing alpha channel.

Hello. So, i’m a newbie to the program. So, i’ve been having problems and i’ve been getting a white background. I know i must sound stupid, but… help?
Here should be some screenshots of in engine. They do have a transparent background, and i’ve been sitting here for 2 hours messing around. I use gimp, as i cannot acquire a license for photoshop at the moment. (Most of what i’ve seen is people showing photoshop.)

Try reading the wiki.

The texture sample has 5 outputs, RGB, R, G, B, and alpha, which is the last bullet. You’ll want to plug that into the opacity mask.

You’ll also have to set the blend mode to masked blend mode. See Material Blend Modes | Unreal Engine Documentation
