True Photorealism in Real-Time
summary
A McLaren car configurator runs in Unreal Engine 4 at ~9 million polygons and demonstrates how to get crisp, photoreal reflections by raising reflection capture resolution from 128 to 1024 cube faces (per-face cube maps, roughly a 6K wrap) at a ~384× memory cost, switching GBuffer to 16-bit per-channel normals, enabling High Precision tangent bases, and turning on the dual normal clearcoat (second normal) for layered carbon‑fiber and clearcoat speculars; an Automotive Material Pack with these shaders is available free on the Unreal Engine Marketplace.
