Panoramic skybox, side-by-side and over-under video layouts

Hey,

I am currently looking to build a VR application with Unity 2019.3.13f1.
In this application I want to show some 360° videos and have found a youtube-series on how to include these videos into Unity. The series uses a material with the Skybox/Panoramic shader to render videos. Unfortunately does the tutorial use Unity 2017.3.0f3 and thus has the option to select a “3D layout” within the material, while Unity 2019.3.13f1 does not have this option.

Can you guys point me towards a guide/documentation that shows how to include over/under 360° videos for Unity 2019.3.13f1?

im having the same issue. anybody has found a workaround?
