It’s a setting on each individual light, not a general render setting.
Select each of the lights in your scene, one at a time, and check the Parameters tab for the Shadow Type. Possibly not all of your lights will be set to cast shadows, but the ones showing “Deep Shadow Map” should be changed to “Raytrace (Software)”. Note that the default setting gives very sharp-edged deep shadows, you might want to play around with the other shadow parameters to get the right effect.
I think you didnt get what im trying to say, I want a setting that would mimic that of a raytraced software render because it gives off much cleaner shadow and more crisp than that of 3d delight.
I already tried the raytraced setting for render on my light and honestly its more good especially when it comes to architectural building it gives good clean shadow unlike 3d delight which gives a very noisy and very messy shadow. I want a setting on 3d delight that can mimic the good awesome render result of software (raytraced) render.
@scorpio: I havent used uber enviroment before any tutorial on using one?
