Is this on a new scene or an existing one.
When the error occurs, when the mesh is in the import progress (reading vertices, polygons, etc...), or when Octane loads the scenefile?

Can´t test the scene, i have only 2GB...

Its a new scene.. I can export about 400 objects, then it starts getting cranky :O

In the end after alot of switching between parsing faces and vertecies it just says, mesh load error. Could not load mesh Z:\etc\organs_test.obj

Maybe its Octane that struggling? Its only one material :O

How big is the exported obj?

About 1.8GB...

Merged together the objects... Seems like I get the error when the object goes above 2GB... Will do further testing.

When you select all your meshes and turn on the show selection info in the viewport settings, you will see the total count of triangles.
Write it down.

Next is to open you obj-file and going to the end.
The last face (not me ) looks like this:
f 1995//7933 2005//7935 2004//7936

The last number (7936) is your overall normal count, divide it by 2 and you will get the triangle count which should match with the one from Softimage.
This will ony work, if you have only quads in your mesh, i think...

Another way will be to reimport the mesh in Softimage...

Thanx Face, will try that... After further testing it seems to breakdown at 2GB filesize exactly.. I will try to re-import it into xsi again, and check polycount.

Have tested it to reimport a 18mio triangled sphere, filesize 2.16GB, without any problems.
Maybe a filesystem issue?

I think its the meshes.. Its the japanese 3D body scan stuff, that I've imported with some scripting (947 pieces or something crazy like that).. I will send it to you, because the .obj that I export, I can't bring back to Soft anymore, without it get stuck aswell.. I suspect it has some 2-point polys or something. I usually do cleanup like that inside Lightwave, because it is much easier for me to see the correct poly stats inside modeler, than XSI. But anyhow... hehe I'll throw you a pm Face!

The meshes had as I suspected some crap in them.. I will clean them up now, and see if things will improve

There are many open edges in the meshes. Means that some vertices share the same position.
After weld these points, it should be work i think.
Stupid is, that there isn´t a automatic function inside Softimage to cleanup these vertices...
