Why the aiToon shader doesn't work in Maya (GPU issue)?

[Anonymous]

When i try to use the aiToon this symbol appears in the Attributes and I can't use the shader:

It also appears when I use aiShadowMatte, aiMatte and aiWireframe

It happens in Maya 2017.5 with Arnold 3.2.0.2 and in Maya 2018.6 with Arnold 3.2.1 (both maya have student license)
My GPU is Nvidia GeForce GTX 1070 and it's driver is updated at 430.86 version
I work on Windows 10 Pro v.1803

I can't understand what the problem is and if it can be solved in some way. I hope someone can help me as soon as possible, because I have to use the toon shader for an academic project very soon.

sorry for my bad English 🙂

That symbol means this is not yet supported on the GPU. See https://docs.arnoldrenderer.com/display/A5ARP/Supported+Features+and+Known+Limitations for the list of what is currently supported on the GPU.

Use CPU for academic project.

I tried to Select the Render Device in Render settings>System, but it is already setted on CPU.
aitoon continues to give me the GPU error.

Do you have any issues using Toon with CPU?
