The particle system we have now, is a great step compared to plib, but there is still plenty to do! Beside the known bugs (jitter, transparency) it is not yet possible to controll it completely. As an exapmle the transparency of the particles are static - thye can't be controlled by any properties. Well at least I don't know how... I found some very extreme pics of a dust cloud made by a helicopter which landed on a clay so tell me if exactly this possible with our particle system already: http://www.flugzeugforum.de/forum/showpost.php?p=1009389&postcount=1379 http://www.flugzeugforum.de/forum/showpost.php?p=1009390&postcount=1380 http://www.flugzeugforum.de/forum/showpost.php?p=1009391&postcount=1381 http://www.flugzeugforum.de/forum/showpost.php?p=1009392&postcount=1382 http://www.flugzeugforum.de/forum/showpost.php?p=1009394&postcount=1384 Regards HHS ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Flightgear-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/flightgear-devel
