The thing that’s nice is it has some great out of the box materials. (something I find quite frustrating about blender and its many engines; not having good libraries of simple real world materials.)
The library they include has a feature that converts Cycles Materials to work in their engine with a single button. I would like to see similar functionality with Verge; not only with Cycles; but perhaps this new Radeon Pro Render engine as well! If certain Nodes are not able to be used or converted, they should be flagged and the User alerted; so that they might be able to correct as needed using a different approach.
