The person I’m working with created what is supposed to be a partially transparent texture in TGA format. When I import it into Unreal and apply it to the model however, the areas that are supposed to be transparent are just black. If I go into the material and start adjusting the opacity value I can make it partially transparent, but this makes everything partially transparent. Is alpha ignored or something by Unreal when looking at textures?
You need to plug the alpha channel into the opacity of the material, also change the material type to translucent
