Re: Physics Animation - Flying Doritos Bag [New file uploaded to Carra 2004-04-19 - By ccoles_avengers

Excellent work, Todd! I've recently taken a recess from physics
animations due to my workload on other projects, but this is inspiring
me to start back up again. :)
Couple of quick questions - how long did the file take to render? Was
320 x 240 and MOV the original render size and format? Also, what did
you use to texture the bag? Was it UV mapping?
Cheers.
