WebProper creation of Optix 7.1 TLAS Instance Acceleration Structure. I am trying to figure out how to build a TLAS properly. Using the samples that came with OptiX 7.1 and Ingo Wald's Optix 7 samples, started with a triangle (just the BLAS that holds the geometry) and it works fine (moved the triangle sample of the SDK to Wald's example framework). WebNov 4, 2024 · So, this is an interesting one. The problem here is that there is a mismatch between the motion SRT transform that OptiX uses for traversal and the one Cycles computes for shading. Which causes these artifacts. OptiX essentially expects a SRT with a scaling/shear matrix of the form
