Yeah, you're right Silverblade, the default action is unwelded and it gives you the option to weld near the end of the import. Leaving it unwelded dispite the massive list of objects it generates is better on memory. I've tried to import objects with no textures in the range of 2 million polys or so and I get memory errors but if I split the 2 million poly object into smaller objects Vue becomes able to handle it.
