Hello,
I am importing files that are not unusually large inside of C4D, but they are taking huge amounts of time to load into the Octane plugin.
Some of them wont even load, and will max out my ram (32 GB) while "updating" the plugin leading to crashes.
The file I have attached that will load but it will take about 8 minutes to load. https://we.tl/B7pVls0dnb (1.5million poly)
The file is .ABC but i have the same issue loading other filetypes (obj, FBX, etc..)

Octane Viewport says it is using 1.15GB of ram.
My question is - what makes this file unique? I can't quite figure it out. I have loaded other files that have many more millions of polygons then this one and have never run into issues before.. Hopefully you all can spot something I can not. Thanks!
Strange loading times.

The problem is the way how the geometry is arranged. It looks really cool, but there are various areas, where there is an insane amount of very elongated triangles, especially at the marked place:
This is this area zoomed in;
When this geometry gets compiled Octane has trouble finding a sensible subdivision scheme and you probably run out of memory causing the system to start swapping:
I don't think there is anything we can do in the near term, but I will add it to our test cases for when we are going to overhaul the geometry pipeline.
