Unity - flickering skin & eye shaders

I’ve imported an iClone model into unity via V Soupday’s Unity Importer; the skin and eyes are flickering in scene view and the shader previews.
Is there an adjustment I should make to the shader graph, or a step I missed?

Switching from RL_…Amplify to RL_…Shader Variants appears to stop the flickering. :bulb:
