Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Material Editor Crash Vecor3

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.

Launcher version, intel HD graphics 4400 ( this laptop http://www.amazon.com/Acer-15-6-Aspire-Laptop-E5-571-563B/dp/B00OOD0IHE ) Nothing in the windows report queue, here's all the logs I see commonly asked for in other threads: Logs and stuff.

Product Version: UE 4.8

Hello Hollywood Blues -

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:

https://downloadcenter.intel.com/download/24964/Intel-Iris-Iris-Pro-and-HD-Graphics-Driver-for-Windows-7-8-8-1-64-bit 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 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.

Thank You

Eric Ketchum
