Ambient Channel and DAZ Toon Shader

digitani

Hi all,

It has been a while since I tried to do any toon shading with DAZ Studio, and I am experiencing something that seems different than what I was expecting.  When I apply a toon shader to a sphere, the toon shading is only applied to the diffuse channel and not the ambient channel.  Whatever color I put in the ambient channel gets applied with a smooth gradient.  I am using the 3Delight engine.

The attached image shows the problem.  The diffuse channel is white 100% and the ambient channel is red 100% to make the issue clear.

Is it supposed to work this way?  This seems wrong to me.

Thanks for any help!

I guess it's a design decision - What effect are you wanting to achieve?

I was wanting to be able to use the ambient channel in my toon renders to determine the color that unlit areas render.  I thought this used to behave differently.  Am I wrong?  It has been years, since I tried to do this in DAZ Studio, so it was a much older version last time I tried this.

Update:  After more experimenting, it seems that it only does this gradient when you provide a non-greyscale color for the ambient channel.  If you make it grey, then it is toon shaded.  It still does not do what I want, but it is toon shaded.  Very strange behavior.
