I read it careffuly, and tried to do that, but it doesnt help

I downloaded some zipped materials for vray, than i extracted them to
C:\Program Files\ASGvis\Materials
I got 2 pictures and one vismat file from each zipped file.
Than i went to sketchup and rendered some model with materials, but they are all black, no materail
Anybody know what should i do?

Thanks!

Sry i forgot that most peple here speaks English...
E da zaboravio sam da kazem da je projekat extra, svaka cast!
Ne znam ni sam sta da koristim, slabo sam upoznat sa renderingom...

e jel zna neko od vas sa ovih prostora gde bi mogao da nadjem neki tutorial za rendering na spskom, hrvatskom, bosanskom ili crnogorskom?
I uopste jel imaju negde da se nadju tutoriali za sketchup na ovim jezicima?
