Oconv: system - out of object space: Not enough space error

Hi Radiance community,

I'm trying to generate a BSDF file from a very dense mesh.

The Radiance file is around 8 GB and when I try to generate the .xml file
using gebBSDF it gives me the "out of object space error"

Oconv: system - out of object space: Not enough space error

Could not compile scene

I found an old discussion about the same warning which suggests some
changes to source code (
http://radsite.lbl.gov/radiance/digests_html/v1n1.html). I wonder if there
is an easier way to address this issue?

A smarter solution is probably to create a smaller part of the panel and
copy it around (which is what I'm going to do next) but I wanted to make
sure that I need to do so.

Thanks,
Mostapha
