Vray not show materials

Hello, I new to Sketchup, today i downloaded texture and apply to my project ,unfortunately when i use Vray to preview, it not showing, but in original project, it showing ok, you can see image below.how to fix this prolem? hope will recevice answer. Thank so much


Not sure it might be it, without checking the file itself, but it looks like the top part (the metal grid) isn’t showing, maybe because the faces are reversed ?

Right click on a face of the grid, and reverse it. Then try again. If it works, then ensure that all of your faces are recto (and not verso)
I recall someone saying that vray doesn’t like reversed faces.

(if it doesn’t work, can you chare the file with us please, so someone with vray can open it and check it on an other machine?)
