A dedicated website exists for PBLi at http://www.pblinteractive.org
which is maintained by CBIT, at the University of Queensland. The
website contains a brief FAQ, which is likely to increase in size
over time.
As CBIT is exploring a commercial version of PBLi, it is likely
the FAQs listed below will be addressed in updated PBLi program
documentation or on the dedicated website. For now however, I've
listed some here, based on the inquires received from early adopters.
How large is the default environment image window? (Answer:
