How to use IES Lighting in your 3D app and how to edit IES lights. (Use them for volumetric lighting). More info and examples at facebook.com/scififunk

IES lighting (Illuminating Engineering Society file type to describe lighting volume, fall off and shape) can be used to add realism to your renders.

After describing what IES is and where you might use it, I show some site which give free IES lights and (more importantly) how to edit them (plus create your own IES lights).

Ultimately you’ll probably have to create and edit your own (to match your work up against a source photo) and I show 2 programs which show you how to do this.

Please note, the pictures look better at http://www.facebook.com/scififunk (the colours haven’t been compressed as you see them on youtube).
