VRay ies lights

V-Ray V-Ray for 3ds Max General

If the target line is switch on for these lights, does it play any role how long this line is or not?

Thanks

Nope, only the direction matters, since the target is used only to determine the orientation of the light.

Best regards,

from a quick test (two planes that form floor/wall and one vrayies light by the wall) it appears that it does not.
