  1. Efficient point rendering

    I'm rendering a big point cloud from a BGEO file. The only thing that changes is the camera animation. If I use the interactive renderer then the scene updates super quick and renders at about 10-20 secs a frame. If I render using a mantra ROP it takes about a 60-70 seconds. I'm assuming it reloads the geometry every frame (or something!?). Is there a way to get something like the interactive render speeds in Mantra? I've tried using delayed load and disk primitives and also various renderers in Mantra (e.g. micropoly, physical) without much success. There is no lighting or any other vex or vops or anything going on. Simple constant shader. Thanks Simon
  2. Hey , I've been trying to use the pcwrite node inside a pyro shader to output a point cloud that will hopefully contain the shading values at render time. Ultimately Im hoping to use this point cloud to bake out a volume light and either use the point cloud or a volume created from it to shade my final renders. Ive got a scene ive tried to get the pcwrite to work with, but ive had no luck.. I've only seen it working with polygon geometry and not yet in a volume. Ive tried combing the forums but haven't had any luck. Any information or guidance would be great. Cheers!
