whoa, it'll make some couple of hours read. thanks, saxon, i guess i'll give it a try. i was looking for some tools for creating 3d environment that is interactive to some extent but i ended only in licensing some of the game engines. there is also a "qoobee" software (formerly nemo), but i was reluctant to dive in, because one has to be a programmer and to learn their script language. i made some apps with lingo before so i guess i wouldn't have to start from the scratch, though i stopped working with director with ver. 4.
