[RSF]

Hello!
Can't make Vray work properly in my new pc.
I have a feeling there's something I must change in the windows settings but...I'm not sure and can't find it in the foruns.
Here's some renders of a scene in the new pc:




and how it should be:




The material that doesn't receive GI is a darktree with transparency as a parameter and...no shadows

Please help?!
Thanks

Well...found the "separator" thing...
I have "." as the decimal symbol, "," as grouping and ";" as list separator
Nothing changed
I have max 7, and the lattest vray (1470370), windows xp pro sp2 and nvidia GeForce 6600 GT
Any ideas?!
Thanks

Hello.
Sorry...was wrong about something...
The problem is only with darktree materials.
They dont cast shadows and if the have transparency they don't receive GI.
Anyone experiencing this?
