Descripción
GT-VBAO is a native C++ implementation of Ground Truth Visibility Bitmask Ambient Occlusion for Unreal Engine 5. It uses a visibility bitmask algorithm with cosine weighted hemisphere sampling to produce occlusion that is physically accurate and closely matches the output of a brute force ray marcher, while remaining viable for real-time use.
Features:
Path Tracing Accuracy Cosine weighted hemisphere sampling produces occlusion that is physically correct, getting closer to path traced results than traditional screen-space methods.
Natural Halo Elimination The visibility bitmask assigns thickness to occluders, eliminating halo artifacts naturally without hacks or workarounds like other methods in the past.
Full Resolution Output Captures fine geometric detail that downscaled techniques miss.
Lumen Ready
No Setup Required Drop into any existing project without changes to materials or lighting.
