Currently, the Hypershade does not support the following:
Only UV tile images within the UV range of 0 to 1 are previewed in the Material Viewer, and only the first tile is previewed. To workaround this issue, view your soloing results in Viewport 2.0 or preview your flat texture in the UV Editor.
Because bookmarks are not supported, the recommended workflow is to use work area tabs instead.
The Fluid shape and texture nodes do not render in the Material Viewer.
