Render does not start and Modo crashes after

[RobertRay]

Yes, well my renders are used at business events and sometimes it is printed on a wall where people walk by. Then I need this kind of resolution

vladimir.nedev I'll will send you the file by wetransfer, it's a large file.

Just took a look at the scene.
It has a huge amount of part tags.
This is caused by CAD import and slows down the translation from Modo to V-Ray a LOT.
It also slows down other Modo operations making it harder to work on the scene.

You can delete the part tags by selecting all your meshes (Select -> Item Types -> Meshes )
and then executing a Geometry -> Polygon -> Set Part... command with a "Default" name for the tag.
If you click on the drop-down menu in this command, you will see (after some waiting) all the part tags that are applied to polygons in the scene.
