Realistic Decomposition [UE4]

Looking for a more realistic way to dispose of your characters? Add Realistic Decomposition to your game! This asset can be added to your project in less than two minutes and is entirely non-destructive!

Watch your characters decay and rot over time, as flies make their home and maggots begin to spawn from the peeling flesh. The fabric will stain as the body decomposes underneath, moistening and seeping through to the surface. The skin and fabric will then begin to rot and dry out, becoming more wrinkled and decomposed over time, before fading away to ash, leaving nothing but a pile of squirming maggots.

1. Easy Setup - Add the component, add the material function, customize to your preference and call the Begin Decay event On Death! That's it!
2. Light-weight, flexible and works with all material types and skeletal meshes. E.g. flesh, fabric, hair/fur, eyes, etc.
3. Niagara System and Material Function controlled by BP_Decay component can be customized to suit
