HELP PO: INTERIOR RENDER (DARK RENDERED AREAS)

Hello po mga sir!

Need help po regarding rendering interior scenes, I have this problem with dark areas, some sort of dark reflections/spill from dark material, I'm not sure how can I fix them. I hope you can give me suggestions on what to change in my render settings/material settings. I'm currently using Sketchup 2013 and VRay 2.0. Here are the changes I've made from the default render settings.

Environment
GI - Texsky
BG - TexBitmap

Camera
Shutter Speed - 40
ISO - 100
F - 7.0

Irradiance Map
-4 , -1 Hsph 60

Thank you po.

try to use a vrayoverrridematerial sir

try increasing the value of "Interp. Samples" under Irradiance Map tab. Try values from 40 -100. see if this works.

Thank you po mga Sir!
