Why arn't my colors showing up in the render?

[gogeta14]

Hi,
I'm using sketchup. I was doing some testing to see how my project would look rendered, and the colors are not showing up completely.

I'm not sure why. It looks like a few of the textures are showing up, and the right wall has some color. The chair and bamboo too. But nothing else it. I only let it run for a little bit like 10 mins.

The room is supposed to be vivid, with rich colors.

What am I doing wrong? Thanks.

hi gogeta!
Post a SU view too, so we can know what you're referring to..

Moreover, check with the monochrome view within SU if your faces are all white, and not reversed. You have to assign materials to the white faces if you want them to come out in the render..

Here is how it looks in SU

I would suggest checking your front/back face orientation as Pibuz says. gl
