About

Single-draw-call blob shadows for 10,000+ units in Unreal Engine 5 - every shadow sharing a mesh and material is one instanced static mesh component; projection, light-direction stretch and ground blending come from per-instance custom data in the material. Built for RTS and crowd rendering.

Material-Driven Shadows — Massive Unit Shadow System

Single-draw-call, instance-batched blob shadows for 10,000+ units. Every shadow that shares a mesh and a material is rendered by one instanced static mesh component; projection, light-direction stretch and ground blending are driven entirely by per-instance custom data in the material.

Supports Unreal Engine 5.8. Full C++ source included.

Documentation, free and without an account: https://wiki.teufel-engineering.com/en/MaterialDrivenShadows/documentation — installation, quick start, the full API and the master-material recipe.

The same manual ships with the plugin as Docs/DOCUMENTATION.md.
