i have the latest one i guess.

Hello. I have a file of 180mb+, a kind of complex project for thesis. But when i tried to render the file, it rendered just the background (the blue one with gray) and my model seemed to disappear when rendered. What do you think might be the problem guys? I tried everything i know to fix it (e.g copy and paste it to a new window, purge it, i also used cleaner) but this methods doesn't fix the problem totally. I can't try the explode thingy cause the project is too complex that it might take too long for it to explode.

Please help. Thanks guys and godbless.

PS: Im using sketchup 2015 with vray 2.0
