ObjectVolumeSphere with fog is limited in size!

[koshman86]

in samples\objects\volumes_01, I try to set one of the spheres to get big enough (I need about R=7000). But when the size reaches about R=1500, the fog starts to disappear, depending on distance from camera.

 

I tried ObjectVolumeBox instead of ObjectVolumeSphere, - the box works fine. The sphere with volume_light_base material also works fine at big sizes. But I need a big fog sphere.

What is your far clipping plane distance?

[koshman86]

Camera Far clipping is 100000.

For the sphere of radius=1500, the clipped artifact begins at distance ~1205 and more, also the fog comes broken when the camera is close enough (distance ~75) and inside.

It is a driver issue with what seems to be loss of precision. On my ATI it works completely fine, while with NVIDIA cards you get what you get. Our devs will looks into this.
