Sample Decorrelation in BRDF Preconvolution for Image Based Lighting Introduction During my time as a member of the HDRP team at Unity, one of the systems I contributed to was the split-sum approximation-based image-based lighting, more precisely for the Sheen light…

Found and solved a years-old bug in Unity's HDRP IBL system. Turns out using the same sequence for every pixel + a local basis with a singularity leads to visible seams on rough metallic surfaces (who would have thought?).
