Lighting Advice Request

So far in all my renders/animations my lighting process has been "move the lights around and see what looks good" using both single lights and the light kit from the DAG utilities menu. Is there any particular trick that you guys use to make the lighting look good? Sometimes mine turns out well, sometimes it looks like crap no matter how much I move them around and screw with the sliders.

Best thing I could tell you is to look at tutorials on on 3/4 point lighting. It's what you use in photograph to set your scene, highlight your model, and draw focus to certain areas. Also remember that a fair amount of post-processing work is done by a lot of people. That gives you a lot of flexibility in working with your lighting, and general scene. Some people do all the light work in Photoshop, or GIMP. I can't really help with that, as I'm still learning it myself, but I hope that's a bump in the right direction for you.

I use three different lights. Shadow Filter Size should ALWAYS be zero. You may notice that the edges of shadows are pixelated though. That's okay, just raise Radius a bit. Also, Shadow Depth Bias and Shadow Slope Scale Depth Bias should be set as low as possible, but since you'll get artifacts, raise one of them until the shadows look right. Also, there are rare times where the lights should be pure white. At least push a color slider a bit to the left. Make sure to make use of the clip editor (while viewing through your main camera) to preview how the lighting looks. That way, you don't have to render again and again to get your image right.

Really? I was told they should be set on the higher settings, to avoid those same shadow problems. Guess, I still have more to learn. :oops:

The trick is to get as low of settings as possible while still avoiding artifacts and making the shadows look their best.

The lighting rig I use is a light behind the model to add background lighting. Usually blue. Then I put one in front of the model, the color can be changed depending on what mood you want to set. And then a subtle one on one side of the character. Make sure to not make it too overbearing.
