Skeletal Decals

Skeletal Decals is an Unreal Engine plugin that eliminates decal drifting on skeletal meshes by handling decal calculations within the material through custom HLSL, using a render target as an efficient lookup table.

Key Features:

• High Decal Count – Configure the decal limit to match your project’s performance budget.
• No UV Requirements – Works independently of UVs; no pre-baked channels needed.
• Built-in Randomization – Features random rotation, scaling, and atlas-based texture selection.
• Modular Mesh Support – Seamlessly handles characters with multiple skeletal mesh components.
• Efficient HLSL – Optimized shader code minimizes texture samples and calculations.
• Integrated Animation – Native animation system similar to Unreal’s standard decal component.
• Blueprint-Accessible – User-friendly design for Blueprint-oriented developers.
• C++ Performance – Built in C++ for optimal runtime efficiency.
• Full Documentation – Comprehensive guides and references included.
• Multiplayer Ready – Visual effects replicate in multiplayer, with an example project showing implementation.

Overview

The Skeletal Decal Component is an actor component that manages configuration and logic. It supports replication, save/load, and copy decals system, and operates in two distinct modes:

1. Projected Mode: Emulates standard decal projection within the shader with rotation control.
2. Sphere Mode: Uses two sphere masks for simple, high-performance impact effect or mask.
