Latest update for Maya 2019 (2019.3.1) breaks aiToon shader. Same with Maya 2020.
What we have noticed this far is Stylized Specular and Rim Light do not take the lights and, in the case of Stylized Specular, do not take the textures.
Our temporary fix at the studio was downgrading our LookDevs to Maya 2019 and, since there is no way to get a very specific version of Maya (specific update to version 2019), they apparently have to stay on that version until Autodesk fixes both this issues.
Is there anything I can make on my end to fix this issue, or do I have to wait for an update that fixes this problem?
Thanks in advance from me and my team :)
