In this Unreal Engine 5 tutorial, you’ll learn how to create efficient bullet hole decals using sprite sheets (texture atlases) instead of individual decal textures.
This approach uses one master decal material with randomized atlas selection, making it more memory-efficient and scalable for high fire-rate weapons and AI combat.
Built in Unreal Engine 5.7 using the Shooter Arena template.
