Quote - This little circuit can be used to soften a terminator.

I use a Diffuse node to measure overall illumination. I run that into a SmoothStep (using a 5x multiplier). That means any illumination from 0 to 20% will be smoothed.

Run that into a Blender. I set the Blender Input_1 to a value darker than white. Input_2 is white.

This is your new Diffuse_Value to plug into whatever your'e already using for Diffuse. In my shader, there's a Diffuse node somewhere you'd hook this to. It probably already has something plugged into Diffuse_Value. Whatever that is, plug that into both inputs of the Blender, then connect the Blender to the Diffuse_Value.

You can adjust the intensity of the softening effect by how bright the gray value is in Value_1 of the Blender.

The Sphere on the left doesn't have the circuit. The one on the right does.

Rendered with Poser Pro GC. You'd get the same effect in Poser 7 with my shader, but the gray level will act differently.

i tryed those nodes now. doesnt work good when we are using an IBL.
