Thanks for all the feedback everyone. >> Not the one with the big arches, the one with all the neat CG tools. Well, you've already got Bryce, so, do you mean the blue table cloth ??? :p Just head over to you're local party store, buy a $12 roll of blue plastic table cloth and stick it on the wall. Here's a pic, and a link to the tutorial on how to build the whole thing with around $30 in supplies. (...and yes, all the bacgrounds in the example pics at the end are Bryce renders.) Have fun. :)
