yes i did that already. the second image is actually a render. but my materials do not look as in the vray preview. the setting and the light are the problem.

Hello, sketchup people! it's my fist on the forum.
I need your help. i want to render some interior elevation of e avery simple model. a cut it with zoro so i can actually render it with vray but it look awfull! i can see my lights and stuff work... but i have some matte and glossy materials and all the render looks chalky. i read thtat i should use an exterior rendering application but i want to render it with vray because i have my deadline in 8 hours and i want to use a program that i actually know.
can anyone tip me about how i can get some decent interior renderings of a section? thank you!
