[Problem] Vray For Rhino + Lights

[K4rl33]

Hi guys, I'm a newbye and I'm experiencing this problem with rhino 5 and the last version of Vray.

Settings: Express_Very_High.visopt

Light: Emissive material applied to a surface

Near view - no problem -



Far view - problems -



You can see the light through the shape in the far view
...and the more you get far with the camera, the more the light come out from the shape with blotches.

How to fix it?

Thank you

Probably your IRMap is too low. Post your settings?

Check sample visibility? -> http://www.spot3d.com/vray/help/200R...vancedimap.htm

or you could try to enable DE to avoid this light leaks

At 1.5 the emitter layer can be set single sided (default), so that light goes in one direction only.

if you are using Ligh Cache you can also enable the retrace threshold to avoid the light leaking.

Thank you guys.

The problem has been solved enabling the retrace threshold and setting a deloney triangulation interpolation method
