Huge OBJ file importing ... RAM issue

derei

I'm trying to import a rather huge OBJ file (~1GB), using TIG's Obj Importer (https://sketchucation.com/forums/viewtopic.php?t=20584). I have 16GB of RAM and the import goes rather quick until it reaches ~8GB in ram, at which moment, the plugin asks for Model Units (i choose Meters, to make sure I reduce the chance of not generated faces).

Anyway, after the model starts to be drawn partly and my RAM goes to about ~9GB, it slows dramatically and I don't know why... could be the plugin, but I am tempted to assume is the pagefile... maybe, for some reason, the system is moving the data in pagefile, which may slow the import greatly.

Is it any way to force SU to stay in RAM with all its baggage, rather than dumping parts in pagefile?
... or if you think my issue is of other nature, please let me know. I'm open to anything.

Thank you.

Did you try Fluid Interactives OBJ importer?

It is written in C so parse files very quickly.

There's a 5 day trial

Thanks, I'll try it now. I tried the one from SimLab, but that one crashes once the RAM is full (and I have plenty of pagefile too...)

Fluidimporter crashes at start and freezes my system... so, I believe that's out.

Thanks anyway.

Did you try Blender to import it?

1GB is a big ask for any app. But Blender might be able to better segment it to export more manageable chunks.

Is the 1GB purely mesh data or mesh and texture data?
