Skylight...no overbright

[mmikee]

I am working on a kitchen scene and when I placed vray lights at the windows, which I normally do, I get alot of overbright mat errors. My question is not really about the overbrights. I have read a great deal on this forum about those. My question is... When I turned all the vray lights off and just used the environment/direct combo I no longer had overbright errors. Any ideas why ?

I will go through the scene and isolate the problems causing the errors in the first place, but I found this to be very strange.

make sure your vray lights are not sticking thru any geometry if possible.
Also try turning down their intensity and see if that makes a difference.

It also could be some sort of material problem. So try putting a default gray vray material on everything and render with the vray lights as they are now and see if you still get the errors.

Thanks for the tips Daforce .
This will sound pretty dumb, but the arow pointing out of the Vray plane light can intersect objects, right ? It is only there for directional perposes ? Only the plane itself should not intersect objects ? I always make sure that the lights are not intersecting anything. Im still curious as to why with skylight/direct overbright errors are not present.

heheh thats cool. The arror is just so you know which was its facing. So it can intersect.

The skylight is generally a much softer light and usually fairly evenly lit.
When you use vraylights they are very strong up close and fade away at distance (decay) so if you have objects very close they get very bright, And that can sometimes cause the error.
Although often it is a material problem, it could be even caused by objects that are not mapped properly i believe or even the use of the max raytrace material or architectual materials. So try my suggestion of the default vray materail and see how you go

Will do, and thanks for the quick response.

no problem.

Let me know how you go
