Well, I think that I read that the response time of the support is like 2-4 business days? Anyway, so say that is like 2 questions per week, so roughly 100 questions per year. It’s assumed that the discussion will evolve into more and more difficult/specialist subjects, which would likely take more and more time for support to respond, so maybe the number of questions is more like, say, 75 per year.
My difficult questions relate to the fine control of particle emission in Niagara, texture sampling of 3D grids in Niagara, and hardware ray tracing / making Niagara fluids cast light and shadow.
