Cell shading issue...

[Anonymous]

I've created a Shaded Brightness three Tone and applied to a surface in a scene with 4 different directional lights but when I make a Render it the shadows looks terrible. I need to know what can I do to fix this. I've attached an image with a render showing the problem.

The sphere looks kinda blocky - have you tried increasing the tesselation?

Also try softening your normals.

Sorry for the delay, I've tried to increase the tesselation but doesn't work.
About the softening, how do you soften the normals of a NURB Sphere?

Thanks for your answer

Can you upload your scene file?

sure, here you go...

Is this a Maya 2015 scene?

Can you save out a .ma file - (Maya 2014 here...)

[Anonymous]

it's a Maya 2014 scene.

And won't let me save it as .ma, when i try to save displays this messaje: "file contains unknown nodes or data. To preserve this information, the current file type cannot be changed."

Hmmm, I'm getting an error message when I open the file in 2014 here:

requires "cartoonShader60" "6.0";
# Error: line 1: RuntimeError: file <maya console> line 1: Plug-in, "cartoonShader60", was not found on MAYA_PLUG_IN_PATH. #

Is cartoonShader a 3rd party plug-in you installed?

Also - when I look in the hypershade, I'm not seeing a toon material - how did you go about creating the material you are using?

[Anonymous]

That's weird, I've used the Shaded Brightness three tone in the Toon menu.
I've cleaned some settings in the file, try to download it again please.

Still no luck... when I open your file and look at the hypershade - there is no toon shader.

I've just created a new shaded brightness 3 tone material and assigned it to the sphere...

One thing I"m noticing though is you have a directional light with depth map shadows turned on - that may actually be what's causing that rough terminator in your render. You sould be able to tweak the resolution and filter size to lessen the issue you are seeing -or- possibly used ray traced shadows instead.

Thanks!!! that worked perfectly!

Glad to hear.
