Hi Metzger,
From the sounds of it, it seems like you’ve got a very complex mesh to be that large in size. I’ve got a test mesh asset that is 1 million polys and it’s only clocking in at 159mb. That file can take 5-10 minutes to import with our machines.
What is the poly count on your mesh?
While there is no limitation based on the number of polys your mesh can have, but there are limitations on how much your system can process.
What are you system specs? You can post your DxDiag here and it all cover all the information. You can get your DxDiag by going to Start > Run > DxDiag and then save all information. This will output a text file.
Thank you!
Tim
