Unreal 4.8 and 4.9 preview material editor crash
Hello, I have been using unreal for a while, and since using 4.8, I haven not been able to open the material editor and use the texture node specifically. I can use vectors, lerps and anything else like that. But as soon as I add a texture node, it crashes.
I have a GTX 760 4GB, Intel i5-4690k 3.5ghz, 16GB ram...

Hi Piplington -
The windows error that you are experiencing is being caused by an out of date Intel Integrated Graphics Driver (the igusc64.dll). With some of the new additions to our Post Process and other improved Rendering pathways in 4.8, these older drivers are not able to handle the newer information. So to fix that problem, you will need to download and install the latest Intel Driver that can be found here:
Now you list that you have an Nvidia GTX 760, if you are running on a laptop then another problem exists as well. Your Nvidia Optimus program which handles the switching for power saving purposes is not seeing Unreal as needing the Nvidia card and defaults to using the Intel card for power saving purposes. You will need to go into the Optimus program and set UnrealEngine.exe to always use Maximum Performance and the Nvidia card.
