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"

Building Level Crashes

Hello. So here's the deal, upon clicking Build Level Unreal Engine 4 crashes. It happens every time. Here's a screenshot.

Running Build: 4.9.1-2689999+++depot+UE4-Releases+4.9

Specs: Windows 8.1 Intel Core i5-4300Y CPU @ 1.60 GHz 8GB RAM 64-bit x64-based processor

That's all the information I've got.

A fix would be great. Thanks guys!

Hi PCCoder1000 -

We have actually tracked down an issue like this in the past. It is a conflict in the drivers for the Intel Integrated Graphics Cards. 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 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.

If you have an AMD ATI card or NVidia Geforce card as well as an Intel Integrated Graphics chances are you need to look at the Graphics Switching Options and ensure that the engine is using the AMD or NVidia card when the engine is running.

Thank You

Eric Ketchum
