to Nayman…my project is almost finished.to your question about did i model the F-22 or not…yes i did. actually i do not quite liketo work with previously modelled things. the project will take longer time than i expected because of the raytracing thing. i am having trouble for the halos that enter the room while i open the gates. i had to write a python script to overcome it. i hope you will be able to see it the day after tommorow(indian time actually coz i am from india).
