and followed all kinds of Tutorials & the Documentation about creating Glas with Substrate.
Change Material from Opaque to TranslucentColoredTransmittance (or any other Translucency Mode)
Enable IOR
Add a Substrate Slab BSDF Node and connect it to Front Material
Add a Substrate Transmittance-to-MeanFreePath Node and connect it with SSS MFP (that should, according to the tutorials, already create a transparent look)
Add a color going into TransmittanceColor
However… Substrate won´t display any nice transparency with the Substrate Flab Approach.
When setting up your transparent material with the Substrate Transmittance to Mean Free Path node to drive the glass color, make sure the slab node has this setting. This made everything work for me in 5.6 with ray traced refractions in Substrate.
I spent almost a whole evening cooped up in a hotel room just pouring through everything, trying everything, comparing 5.5 substrate to 5.6 substrate, and finally noticed that option in there. When there’s no updated documentation you gotta brute force figure it out sometimes lol.
I made perfect substrate glass in 5.5 with all the settings faithfully matched, but now my material previews have an annoying horizontal banding running through them. I think its could be a project setting as this new 5.6 project started from the VR templete, rather than a blank architectural template. The bands are also there in the editor. Any ideas @EvanHammel ?
