This has been around since the new User Interface material Domain was added and is easy to reproduce.

1 - Create a new material, set the ‘Material Domain’ property to ‘User Interface’  
2 - Right click on any node in the graph and select ‘preview Selected Node’, the preview won’t update.

In order to preview nodes for UI materials you have to switch to another domain then back again.

Hi TheJamsh -

Thank you for your report. This issue is currently fixed in our Main Branch, but I did enter a bug report as UE-28547 for the issue in 4.11 Preview.

I’m having a problem with any pack I install, whether it is downloaded from the internet or added from the launcher, even some of the materials from the blueprint do this. Whenever I try to use the material or a mesh, it changes to the grey checkered box pattern. Restarting the engine brings them back but whenever I try to use them the same thing happens. I found out that the texture samples aren’t assigned (node without a texture) but whenever i fix them manually by adding the textures and reload the engine, the problem just starts all over again. Please I’d like some help with this.

Hey DrewCarter101,

This sounds like it could be a separate issue. As a result, please open a new thread in the Bug Reports section regarding your issue and provide more information, such as repro steps so we can reproduce the issue on our end.
