This may be nothing new to anyone but... I never tried using a lightdome before because I wasn't patient enough to go through the exercise of setting one up. I came up with a way to leverage Wings to make the setup completely painless...at least for me it was. The 3 experiments posting below shows a render in which I used the lightdome so created and it came out looking fairly photo-realistic so...I'll try using one more often. Anyway...the beauty of using Wings to create the light rig is that you can select the number of slices and sections on the original sphere which gives you control of how many lights will be in the final dome. Hope this helps.
