Lighting problems

[baptiste]

Hi all,
I have some Lighting problems with an interior scene. I have some splash of light around the down light and along the edges of the windows. It seems to come from the G.I.

Thanks for all the replies and sorry for my verry bad english...

try ticking "retrace threshold" under lightcache?

Thank you verry much Morne,
this works fine, But i still have trouble with the light downe the windows.
i post with this the corridor view with the problem fixed and a crop of the problem in the other view.
I have try to play with the sample size of the light cahe but it doesn't change anything?
if you have an idea...
Thank you.

hi again
The only thing that i have found to fix the problem is to push the irrandiance map presset to verry high wich increase too much the render time. so if someone have an idea to have the same result....
i have posted the last crop with the right result.
Thank you

hmmm different approaches for this, maybe a combination of things.
try any or all of these:
pull sill vertices into the wall
in irmap, tick "check sample visibility"
if still no luck then also in irmap tick "detail enhancement"

how's it looking now?

[baptiste]

Yes!...
thank you again Morne... here is the result
01 Check sample visibility (the best ans the faster)
02 Detail enhancement
03 both

i have bring down the irradiance map preset to medium. before this i have try to play with the clr tresh, Nrm tresh and dist tresh, and i have noticed thet it doesn't fixed the problem.
So....
thank you, always a pleasure to learn something, and to find help
