Hi Steve, MoI v2 makes use of multiple CPU cores, so it has more meshing happening concurrently than v1 did.

Each thread doing its meshing will consume some memory while it is working for holding intermediate results, so there can be a larger spike of memory use temporarily during the calculation phase along with that.

If you'd like to avoid that, it is possible to return to the v1 system of meshing happening on only 1 thread by a setting in moi.ini :

[Mesh Export]
ThreadLimit=

Set ThreadLimit=1 to return to v1 peak memory use behavior. Of course only using 1 CPU core will take longer than using all your CPU cores.


But instead of doing that, if you are dealing with complex dense meshes I'd recommend switching to a 64-bit version of Windows which will roughly double the amount of memory that is available for MoI to use.
