Does RC have a "Limit to Visibilty" function?
« on: July 05, 2015, 06:27:12 PM »
The "Limit to Visibility" is a very useful and necessary function in ForestPro for huge scenes. I can't seem to replicate that in RC. I was following the stadium tutorial and noticed some speed differences between the tutorial and my machine. I have a pretty hot machine with a super fast i7, 32GB Ram and a Quadro K5200. The tutorial populated the chairs and people within seconds but it took my machine several minutes for each and in one instance, crashed it. I think that if the instances were clipped by a camera view, it might have helped.

Is clipping possible with RC?

Hi,

I'm afraid that RailClone does not currently have an equivalent to Forest Pack's Limit to Visibility features. This is because the position of segments in RailClone is always dependent upon their position within the array, so it is always necessary to build the entire array to calculate the position of each segment correctly.

That said, the Stadium tutorial should not be causing such problems and was created and rendered on a machine with a much lower spec than yours. Are you able to open and render the completed scenes from the tutorial downloads?

Many thanks,

Paul

Hi, what render engine do you use ?

There is an important difference between V-Ray and other renderers: in V-Ray the geometry is built dinamically; each segment is processed only when the raycaster hits the bounding box, so it works as a kind of "camera clipping".
You can find more info in the Rendering Best Practices guide.
