SpencerL Posted September 30, 2006 Share Posted September 30, 2006 I have a high res model that I am using the Poly Reduce SOP on. I am using the Poly Reduce based on the Distance option. My problem is that the distance threshold only allows me to enter a value no greater than 100. Am I missing something? The camera distance to my object is around 5000 so I need the distance threshold to be >5000. I am not sure what I am doing wrong...any suggestions would be great, thanks!

edward Posted September 30, 2006 Share Posted September 30, 2006 I think you misunderstand what the Distance Threshold parameter does. From the help, Dist. Threshold: The world distance at which the polygons should be left at full detail. This means that _no_ polygon reduction takes place when the distance to the camera is less than this. If the distance to your camera is 5000, I think you want polygon reduction right? Which means that a value of 100 is fine. As soon as your camera is within a distance of 100, your polygon will have the maximum number of polygons. Quote Link to comment Share on other sites More sharing options...

My camera will never be closer to the geo than 5000. So basically I dont want any reduction done when the distance is <5000, but as it is now it reduces when its <100. Therefore with my scene, everything is being reduced since all my geo is >100. Quote Link to comment Share on other sites More sharing options...
edward Posted September 30, 2006 Share Posted September 30, 2006 You can use the Percentage option with a custom fit() expression derived from the camera distance then. To get the camera distance, it's something like vlength(vtorigin("..", "../cam1")) Quote Link to comment Share on other sites More sharing options...

I appreciate the help. I still wonder why the functionality of the Distance parameter of the PolyReduce SOP does not go above 100... Thanks again.
