Hello
I am doing some RnD with vray toon mtl and I am stuck with something. Hoping someone can chime in with ideas.
I am trying to get a soft grass look, but has subtle color changes. The way I achieve it is to plug a noise map (set to explicit map channel) into the diffuse channel, and set the whole of diffuse ramp to white so there's no harsh shadow that's created by the grass, as shown in the image below. I also untick the "Cast Shadow" under object properties of my grass.
but as you can see, it also removes the shadow that is supposed to be cast from the spheres. If I bring back the diffuse ramp and set it to blue tint, there's proper shadow cast by the spheres, but the grass itself lost the soft look and there are darker shadows present, which is not desirable to me.
Is there a method where I can have a blend of both? The only way I can think of is to sample the plane where the shadow is cast in realtime, and plug it in to the diffuse ramp. Either that, or bake the lighting information and then export as image, and bring it back in as bitmap for the diffuse ramp, but this is not an efficient workflow.
Maybe I am missing something obvious. Does anyone have any ideas? I am using vray sun as a single light source.
