yes Jim, you can find them here:

https://www.blackorb.com/maya3dtutorial.html

scroll down!

I am not sure if this is illegal or if blackorb have permission to show these, but I done a simple search in google so...

I dont know if wavefront have released these for public use, but if I find out that they dont allow the pdf`s to be shown I will have to close the thread. I dont think the scene files are here

Many thanks

Kevin
