Hello everyone !

I installed my last student license of
Maya, so
2019. And I wanted to try the substance plugin, and.. ..when I am in the hypershade,
nothing happen when I call a substance node. i have any substance node..

And, when I click on the preference of Substance i have this message :
// Error: file: C:/Program Files/Autodesk/Maya2019/scripts/others/getPluginResource.mel line 66: Plug-in resource lookup failed, resource ("SubstancePlugin","kAECacheOutputNone") is not registered
//
Have you an idea about that ? ^^' maybe I missclicked something ?
Thx all !
