I need to create footprints that are only normal maps. I know I would probably do this with decals but when I create a material with only a normal map it turns black. Should I just create a transparent material with a normal map? Also how would I spawn the decal where the player steps w/ correct rotation?
For footprints system you need to use decals
1 - Enable DBuffer Decals
2 - Create simple Decal Material for Normal channel
3 - Apply shader to DecalActor

Thanks, it worked. Although i had to change the decal blend mode to normal for it to show.
