hey,

first is, on any application, do right click on icon in the taskbar, click pin to task bar, then do it again with unpin, this will make any right click option disapear ( window 10 )

second one, for the material, any image put under Detail bump, the image will appears on detail normal icon, and not its own icon.

1) Is that an issue with the engine or with Windows 10?
I don't exactly understand how to reproduce this?
Can you make some screenshots or a video?

2) this works OK, the normal map is generated from the bump map.
In the shaders, the detail bump map doesn't actually exist, it's only used for creation of the detail normal map, which is used in the shaders.

2) oh ok thanks for clarification

1) first pin to taskbar https://gyazo.com/208fb11dcccdf8b1724a5400bbfbc9bc
second unpin from taskbar https://gyazo.com/e93d0dc47c9de8e0066dafa6753284c7
third you notice that it only shows closing anymore, instead of new instance, and pin option https://gyazo.com/fc0b7891122b17c2a080e1dd15244771
i am not sure this bug happens with other platform as i only use window 10, and that's where its been tested. this is with any application from the engine. other application in window works fine [ie. chrome, mozilla, skype...], so i believe this is an engine issue

Thank you I see now. However this looks like some kind of a bug with the windows itself.
I'll report this to Microsoft
