View full threadPerformance: some more alu in per particle output compute, and more alu per pixel, but no texture read. No extra attributes needed. You’d struggle to measure any perf delta, even with tons of embers covering the screen, as other costs dominate (particle compute, vertex, blend).
- First Time Ghost scenes released! ✨ We’ve just published two projects: showcasing the character and the grassy environment scene. Have a look at the real-time hair simulation…
