Fatal error! System out of memory!

Hello, I have a problem.
when I import my 3d model(1.2 Gb I know it’s heavy), Unity crashes giving me the error message. I have 8 gb of ram …
How can I do?

Sorry for my English (I use google translator xD)
Thank you :slight_smile:

Perhaps you should shrink down that model? Is it a fbx?

Not sure if it relates, but remember that Unity is 32-bit, it will not get past the 3-4Gb memory limit. Also, probably, as your model is so huge, when Unity tries to process it, it needs to allocate more than 3-4Gb of memory to parse your file and generate the Unity asset.
The only solution, in this case, is for you to break your model down to several files, import them, then make a prefab with your model assembled as you like in the Editor.
Remember also that this memory limitation applies to build as well.
