Whole or partial scene not rendering

[glimpse]

One addition.

If You use premade assets, models - these might cause that. I've noticed a lot of crashes in 3ds max, that neither max or vray was responsible for, but the meshes, missing textures and all other stuff (like links with unreadible characters etc.)

For stability there might be a lot of issues, keeping an eye on overall workflow, how You organise, saving file increments in different files might give you an idea of what's going on..- i know it sometimes hard, but that's part of the game =)..
