I'm using an area light as a key for my model which is giving me nice shadows.

However I'd like to make the shadows it casts not qute as dark as they are? Is there any way to change the brightness or colour of the shadows an area light casts?

I've tried adding extra lights to make the shadows lighter but they end up making the ground to bright.

Basically, I've got everything exactly how I want it lighting wise except my shadows are too dark. Can I change their brightness?

When you look at the property panel for lights, shadows tab, there is a field to change the shadow color.

When you add fill lights play with their intensity, falloff etc to get the result that you want. You can also play with the ground's luminosity to fake everything.

Another thing you can do is to render your scene in multiple passes and composite everything in photoshop.

usually i use shadow density to setup lite or deep shadow, and if i work with an animation i render out shadow pass, for every motion item...

a nice trick is to use two lights in the same position, one for shadows & one for illumination only.....


create a light, position it & work out the intensity that you need, eg. 100%
duplicate it & turn off shadows on one of the lights
adjust the intensity of each light whilst keeping the added values at the intensity of step 1
what you'll get is a light that creates shadows at whatever the intensity is, the other light is used to increase the overall brightness without changing the shadows. eg: both at 50% - you'll get 50% shadows, shadow light at 20% + main light at 80% you'll get 20% shadow.....but the overall brightness will be the same as using a single 100% light, the only difference is the shadow opacity.

That's a nice trick! I'll try it out this evening :)
Thanks.

Lateral thinking, I like it! :) Thanks!




Shame there's simply not a shadow colour button though! Bah. :(

2 things.

1. There is a shadow color button.

2. Another way to control shadows is a shadow-only light. This only works in LW. Negative intensity, Light color is black, Shadow color is inverse of whatever color you want the shadow to be. So if you want a black shadow, make it white. Want a red one? Make it green. Etc. I made a script that sets this light up for you automatically, and includes an editor that let's you pick the color normally (so you don't have to deal in negative values).

Negative lights are a trick I have always used from way back when there was no color shadows and to fake the GI look ( we are talking DOS days here).... but it always required alot of playing to get the settings just right... this script will come in handy !!

thanks!!!
