Vray rendering only HDRI

[axiaq95]

Hi,

I am using sketchup 2014 with vray 2.0 and I have problems all the time. I am rendering a 14 mb file and crazy things happen when rendering . The following are some things that constantly happen:

• vray renders the hdri sky only and the rest is rendered in all white
• vray materials dissappear and become like glass.
• vray renders all black
• materials in the material editor lose the bump map and when I insert the bump map again and render .. the image renders the hdri sky only ( as mentioned in the first point)

These things keep happening each second and I end up doing something and having to close it all without saving since it would not render correctly. Anyone can offer me some help please ?
