I recently encountered an issue where I could not run the editor without implementing this solution: [UE4 Slow UI - Programming & Scripting - Epic Developer Community Forums][1]
After adding the engine/project paths and -DX12 suffix I was able to fix the speed issue.
Now, when using the Mat_LayerBlend_StandardWithDisplacement node in the material editor, the editor crashes with an Assertion Failed error. The real kicker here is that I am able to run this functionality when not using the aforementioned solution (i.e., running it without the engine/project path and DX12 suffix)
I am at a real loss here. I can’t sacrifice the functionality of the material editor for the speed of the UI and vice versa. I am running Windows 10 on an ASUS Rog laptop, GTX 980m with 64 gig of memory.
I’ve attached an image of the crash reporter. Thanks in advance for any help!
