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"

Adding Decal Component Crashes Editor [4.14]

Hi Guys,

My editor is crashing when I attempt to add a decal component to a Character Blueprint. As soon as you click to add the decal component the whole editor crashes and doesn't allow me to send a bug/error report.

It also doesn't allow me to drag and drop a decal into the Character Blueprint.

Cheers,

Product Version: UE 4.14

I found a fix for the issue. So far, I no longer get the instant crash or the crash when moving around in the viewport if I luckily get past the instant crash. As I mentioned above, the issue was the graphics drivers. Just as a notice, this is for a MacPro late 2013. The fix was to run the AMD Cleanup Utility that comes with newer, albeit unsupported, drivers for the FirePro D700. Then delete "c:\windows\system32\atidxx64.dll". Once that is done, install the modded drivers from https://www.mxdriver.com/ per the instructions provided.

I think the core issue might be that the UE4 Editor is using some methods or classes in the new dll that didn't exist in the old driver's dll I had.

Regardless, thanks for the help! Hope this helps others who might be in the same situation.

Cool, I'm going to accept your answer and delete the unnecessary information that is clogging up this post so others can find the answer more easily. Thanks for clarifying that the crash window won't open.

We call that a silent crash and usually that indicates a problem outside the engine just for future reference (like outdated drivers or hardware issues for example).

I am having the same issue. The problem only exists on one machine. I can add decals on a mac and two other PC's but not the third PC. There isn't much of a scenario but here are the specs from dxdiag:

MacPro6,1 (late 2013 running Windows 10 through bootcamp) Intel Xeon CPU E5-1650 v2 @ 3.5HGz (12 CPUs), ~3.5GHz 64GB RAM DirectX 12 Dual AMD FirePro D700 (FireGL V) 6GB Driver Version for graphics cards: 15.301.2101.0

The graphics card driver is the max I can go using the apple software update tool. ATI has a block on installing newer drivers directly on this hardware so it's either Apple update or nothing. There is a way to install hacked versions of the drivers but first I want to know if this can be fixed with what I currently have.

The Steps: Create a new project -> add a decal -> crash and if the decals were added from the other machines the steps are: Open project from .uproject or launcher -> instant crash

Both of these do not give me the usual popup asking to send crash info to Epic, just the windows crash window that asks if I want to find a solution online. Oh, and it crashes on 4.13 and 4.14 on the said pc.

Any help would be appreciated.

P.S. On the rare occasion that it does load, if I move the view with right-click/move mouse it crashes.

Hi Kinthamen,

Could you provide your Machine ID or a screenshot of the callstack that pops up when the engine crashes? I need that info to look up your specific crash to investigate what is going on.

Thanks,

I don't get a call stack on crash but here are the logs and dxdiag info.link text

It looks like it's my ATI graphics drivers. No fix yet but I will post if I find the exact solution. Event Viewer: Faulting application name: UE4Editor.exe, version: 4.14.1.0, time stamp: 0x5847b772 Faulting module name: atidxx64.dll, version: 8.17.10.648, time stamp: 0x56baa01e Exception code: 0xc0000005 Fault offset: 0x00000000006ce1e4 Faulting process id: 0x34e0 Faulting application start time: 0x01d266d81a5d604f Faulting application path: C:\Program Files (x86)\Epic Games\4.14\Engine\Binaries\Win64\UE4Editor.exe Faulting module path: C:\WINDOWS\SYSTEM32\atidxx64.dll Report Id: 819a7e6a-680c-46ec-802a-312da3a46b1c Faulting package full name: Faulting package-relative application ID:

I don't have the settings as this post but it explains a few things: https://www.armedpineapple.co.uk/tag/atidxx64-dll/

Why it only happens in projects with decals is a mistery to me though.
