I have a model of a building that I’m going to be importing into Unity, but it’s HUGE. I don’t have Cinema 4D right now, it was a model purchased via a freelancer, using Cinema 4D for another project.
I’m getting Cinema 4D installed on a Mac so that I can export it out as an FBX model (I found the page regarding Cinema 4D exports being a bit hosed, so I’m crossing my fingers that the version I’m getting installed at work will be able to export correctly).
The file is huge - broken into 2 140MB models. It’s pretty detailed. Interior with roof off, and lots of “furniture” spread out through a very large building. I’m creating a 3rd-person character to walk through the building for a presentation, but my concern is that it may be too huge.
Being new to Unity - is this too huge for Unity to handle? Should I break down the model into multiple smaller parts in Cinema 4D, then export as FBX, or can it handle the 2 large 140MB parts?
Any advice for an enthusiastic noob?
My advice: just try it and see if it works.
140MB is that pure model (i.e. geometry)? or does that include textures as well? For some reason I suspect it’s with textures, then it’s not a big deal, otherwise if it’s pure geometry then you could consider it big.
From my own experience: I’ve seen Unity import ~250mb model files (although I can’t remember if it was fbx or obj, but that was geometry only). It just takes a while.
Let us know if you have any problems.
Thank you for your reply - I’ve been worrying about getting these files to import - wondering if it would work or not - as I’ve still got to get Cinema 4D installed on a Mac at work, before even attempting it. Your reply instills a sense of reassurance that this should work, once I finally get all the software I need here! 
(and, yes, I do believe most of the file bulk is due to the textures - the geometry should be fairly simple, just many many instances of similar parts - “furniture” duplicated in rows and columns - which is why I was hoping I wouldn’t have to somehow break down everything from the raw file into parts and import and rebuild inside Unity… if that makes sense - I’m a noob at this, so that’s my excuse if it doesn’t)… 
Again, thanks! The support on this forum is superb!!!
