Funny enough, based on a request from another Carrara user, I created a new lighting model last night that does exactly that.

How to use it in the Texture room.

What it looks like in the render. The one sphere and the front face of the spline object have the shadows turned down.

It will be part of the next update to Shaders Plus. Right now it's a simple adjust of the shadow intensity.

Something that just turns of shadows completely can be faster and/or there could be an option to tweak the shadow's color. Any thoughts on those other options? Is that something you'd like to see?

Thanks,
