I’m trying to get my head around Blender 2.8. I’ve imported a model from 2.79 which used Blender Render. I’m now working with Eevee in 2.8 to add materials and textures using nodes.
For some reason I cannot see the Shader viewport! When I start a new file in 2.8 it comes up automatically. It’s only when I try and open this file that I can’t see it.
The Screen Layouts / Workspaces that are active get saved in the .blend, so when you open a 2.79 file in 2.80, the UI tries to replicate the Screens you had in 2.79 as Workspaces, and doesn’t automatically give you any of the new 2.80 ones.
You can click the + at the right end of the Workspace tabs and create a new Workspace from any of the 2.80 templates, so if you’re looking for the Shading Workspace you should be able to get one that way.
