AMD FidelityFX Brixelizer GI is a dynamic global illumination solution available for DirectX®12 and Vulkan® as part of the AMD FidelityFX SDK. It leverages the Brixelizer sparse distance field backend to deliver GI that does not require hardware-accelerated ray tracing.
Currently, Brixelizer GI does not support foliage. Foliage here refers to transparent alpha-clipped geometry. In this two-part blog series, we will investigate Brixelizer GI to pinpoint the problems faced with foliage-heavy scenes.
The second part will explore and extend the Brixelizer GI algorithm to add support for foliage. The blog will also briefly touch on animated foliage.
