Max crashes when starting render

Hello ! Not sure it's solidrocks related, but here's my 2 cents :
- check there's no object very far in the scene...
- check the dyn ram limit to be sure it not override your real ram amount.

one thing you can try : select all you see in your scene, then "save selected"
Then, create a new fresh max scene, and merge your saved scene.
Sometimes it gives good results !

Hope it helps,
