Hey. Yes, I would find this quite useful also. There are definitely things
missing in GG that the developers a> seemed to have overlooked,
b> don't think are valuable, or c> don't want to bother with putting in presently,
or there is no easy C++ function to use for it. These reasons are pretty much
inter-related it sounds also.
For example: An easy sound generator (just a single line of script) would
do for sounds what block making would do for building like you are proposing.
But have you looked at the Leadwerks engine? I haven't tried that out,
but they might have something like you are talking about?
