Every time I open a new material in the material editor, and create a constantVector3, then convert to parameters, the engine crashes. A single vector doesn’t seem to cause it, only when I do a vector3 and break into parameters. I’m on a bit of a cheap laptop, but I just updated the drivers for graphics, and unreal is set to its lowest settings. I’ve tried it with realtime update off, still crashes.
We have actually tracked down this issue. It is a conflict in the drivers for the Intel Integrated Grpahics Drivers. Downloading the newest version of the drivers which can be found here:
will fix the crashing and allow you to continue to build lighting.
I should note that other users have reported that Intel (or their computer/laptop manufacturer) is telling them that they do not need an update. If this is the case, please check to make sure that your driver version is below the 15.36.21.64.4222 driver number. If it is at that driver number and you are still having this issue, please let us know. If not, one user had to force install the new update by downgrading his driver to an older version and then manually installing the driver linked above.
