too much motion blur? I'm running at 125% particle blur at the moment, what should I be having for 24fps?
Shutter speed determines how mutch blurr the moving object will have. A 180 degree shutter spinning at 1/48 a sec will give you the ( assuming your animating at 24fps ) 24fps motion blurr and exposure to match 35mm movie look. Check your camera attributes and see where they are at. I believe the particle blurr you mentioned is for shadows but I guess LW works differently, from what I use. I'm a Maya user, so my appologies if I have made any mistake on that. Does your particle blurr work from sampling?
You stated using LW earlier, I was curious to know what you were using to render out the animation. Are you using mentalray, Brazil, or Renderman perhaps, or are you just using the LW software render'er?
My appologies if I'm way off base here.
