VrayLight behind geometry highlighting edges as if object is transparent.

Hi,
Not sure i`ve described that entirely right. I`ll add an image. A vray plane light multiplier 4 and an object in front of it. You can see the objects edges being lit by the the vray light behind. The material is a default vray material grey. The object has no thickness but even with a shell modifier to add depth the effect is reduced but not gone, particularly close to the edges it`s still quite noticable.
I thought it might just be a weird object but if I create a new plane object in it`s place the same thing happens.
We`re still using 3.40.03 but i`ve tested in 3.6.04 and it`s the same. I also tried resetting the renderer, switching off adaptive/probablistic lights and no luck.
Anything spring to mind ?
thanks

hi,
i know, weird. i thought it might be a toon effect or object visibility, doesn`t seem to be.
i`ll send it on over.
thanks

Hi Peter
as i was preparing to send it i`ve just noticed raising the secondary rays bias seems to help.
aaand i think i`ve just solved it. `too far from the scene origin., possible raycast errors`.. moving it closer to centre seems to solve it. it`s a big scene because it`s space. 3dsmax has never been good at going from small to very large scene scale.
let me know if you still want the scene ?

You've solved it, so no. Not the first time someone reports a problem caused by being far from the origin.
