wow! ok... i hope you don't mind but I am gonna have to go in and edit some of the script. minor stuff... like the window is too small... some scrollbars here and there... changing some float sliders to int sliders... no biggies, but overall WOW :attn: Also- im gonna change the (mostly) thing to Matt B. and Arne OOG. because I feel that you have done so much with this... wow!!! Oh- BTW- the camera lens sensor width... and lens sensor dist- that is a constant value... I hope you don't mind if I remove it. And now I have to put my butt to work and add specular materials!!!! But I still have to create some custom mats... I'll do my best for an Indigo Material Editor window. With adaptive previews of materials... etc. cheers on the great work and have fun on ur vacation talk to ya later -Matt
