I’ve followed Jobutsu’s excellent tutorial to fix the black eye occlusion, but after enabling Substrate, the eye occlusion became black again (PT mode)
Has anyone encountered this? Appreciate any advice!
Jobutsu’s tutorial
Thankfully, Ive found out how to fix it:
After enabling substrate, the Eye Occlusion Master Mat will be Substrate Legacy Conversion
Replace that with Substrate Unlit BSDF
(Emissive to Emissive, Opacity to Transmittance Color)
Also added a one minus node right before Transmittance Col, because it became inverted
Thank God it worked
my case didn’t work 
Thank you so much
