The Easiest Way to Create Bullet Hole Impacts in Unreal Engine With AI Generated Textures
In this Unreal Engine five tutorial, you will build a complete bullet hole impact system using decals, from AI generated textures to spawning decals from line trace hit data.
You will end with a clean, production ready setup you can drop into your weapon system and expand later for different surface types.
This video is part of my weapon and AI continuation, and here we focus on the visual impact layer: realistic bullet holes that spawn exactly where your shots hit, with variation so it does not look repetitive.
What you will learn in this video
How to generate bullet hole textures using an AI image generator like Sora, ChatGPT image generation, or Gemini
How to ensure your texture has a proper transparent background and fix it if the alpha is not clean
How to import textures into Unreal and keep your project organized with a clear naming convention
Why applying Paper Two D texture settings helps for crisp decal style textures
How to create a decal material from your texture and configure it correctly
How to set Material Domain to Deferred Decal and why Blend Mode Translucent works for this workflow
How to wire RGB to Base Color and Alpha to Opacity for a simple, effective decal material
How to prepare multiple impact materials and store them in an array for random selection
A quick fix from the previous episode: replacing Multi Line Trace by Channel with Line Trace by Channel
How to spawn decals directly from line trace hit results using Spawn Decal at Location
How to use Impact Point for placement, Find Look At Rotation for orientation, and randomized decal size for variation
How to set decal lifespan and why unlimited decals can hurt performance if you are not careful
How to test the full setup in game by picking up the gun and shooting surfaces
If you want the next step after this video, it is expanding the system by detecting surface type and choosing the correct decal set for metal, wood, concrete, or characters.
