Material browser is empty while assigning material via Physical Material is still doable

[Anonymous]

Hi,

All of a sudden, Material Browser does not display any materials, but I can still see them in Physical Material window.

I can still add new materials but editing is impossible. 

Any suggestion will be appreciated.

Thank you,

Boris

This is not expected for sure. There aren't other reports of this, which means it could be a hardware problem. Start by restarting your computer. If the dialog is still blank, try graphics drivers. Have you updated your graphics drivers lately? 

In the mean time, you need to edit. You can edit physical materials by right clicking on them in the "in this design" panel in the Physical Material dialog.
