Thanks for all your comments, folks. Much appreciated!
free_ality - I didn’t realize that raytracing could be used on an ordinary render, thought it was suppossed to be used with one of those fancy render programs. All in all I’m pretty happy with the way it worked with the light on top worked out.
Troutmask - Thanks for the texture suggestions. I’m trying to figure out how to get a light wood texture WITH some scratches and scrapes from long use into the mix. Maybe I’ll try the scratches in Photoshop and combine with the wood texture.
I am also trying to figure out how to put an atmosphere on a planet and have the Tardis hovering in orbit. Any suggestions as to a good tutorial on the subject?
Thanks again everyone.
