Optimise SH Baker into larger raycast batches, caching texture data, and SH occlusion sampling using parallel jobs. Handle cases where fbx does not have material assigned by searching local materials folder
Move SH calculations to vertex shader, use Unity shadow fade function for shadow to SHDO transition/blending, remove unneeded interpolators, fixed precision issue causing SHDO flickering when in shadow range.
Encode spherical harmonics directional occlusion (SHDO) into gbuffer for proper shadowing on direct lighting (directional light only), use alpha testing and multi hit backface raycasting in SH baker to better represent foliage shadowing, blend between shadows and SHDO when reaching max shadow range, and use TOD sun direction for SHDO calculation
Spherical harmonics baker (L0, L1) to store self shadowing data in foliage vertices
