Can any max + vray expert solve this over saturated scene?

I'm rendering this simple scene, notice that it's became blueish, if i change the material, then problem solved, my question is, what is the problem in this material which makes color over bleeding?

Hi,
try to:
- apply a vray material to your box;
- apply a vray shadow to your light;
- apply a MtlWrappere (with a low GI emission) to your bluematerial.

This can be a good starting point

thank you for your time, you gave me a solution but not a conclusion from what was the problem, I just want to know, what parameter make this material bleeding, i'm a teacher of 3ds max, and trying to find the reason for every thing.

The three advices goes all in one direction:
VRay supports better its native elements.

For the exagerated color bleeding:
the light you positioned is so near to the bluish geometry that causes strong blue secondary light bounces over a pratically neutral gray color (do you know Kornell box?)...by the MtlWrapper (like in vray object properties) you can controls this aspect.

That's all...or nearly

but if i take the diffuse map to another new vray material and apply it to the same object it will not cause this color bleeding, try it please, i still wondering why

it seems to be caused by the lightcache

Ok, if you disable the gradient map, then theres no problem.

I replaced the max gradient map with bercon gradient map, and that seems to have fixed it.

You can get it here for free (allong with other good stuff):

theres probably some invisible parameter (or script) linked to it thats causing problems?

First rebuild the box (for some reason gives errors) then go to your gradient map and under output check clamp.These steps worked for me.

Correction, give a material to the box (room) .No need to delete it.
Not white (will burn everything).The clamp needs to be pressed for the blue material.
