[Radiance-general] Oconv: system - out of object space: Not enough space error

[giulioandrea antonutto foi]

maybe a silly thing but sometimes the issue is that every polygon is a separate mesh into the same obj file (I think rhino does that with some export settings).
try exporting a small portion and see if this is the case (open the file with a text editor and see), if so then the memory is taken by several repetition of the same lines and it is easy to fix.
anyway good luck, 8GB is quite a record for sure…   you may need to break it in pieces or reduce mesh resolution...
