Engine crashes when I try to attach camera in character blueprint to a bone socket

In Uneal Engine 4.8.3 when I try to attach a second camera to a bone socket in character blueprint viewport (as soon as I click to magnifying glass icon) engine freezes and crashes. I followed this video tutorial:


Previously (in 4.7) I could attach second camera to socket without any bug following that tutorial.

Same issue with base camera.

I started a new Third Person Template but bug remained.

My RAM usage suddenly triples when engine freezes.

Hope these bonus informations help :slight_smile:


Hi Spear,

I haven’t been able to reproduce a crash using that tutorial. Does this freeze only occur in your current project, or can you reproduce it in a new project as well? Does Crash Reporter window come up? If so, please copy information there and paste it here in a reply. Please also attach your dxdiag and log from project’s Saved\Logs folder after this freeze occurs. Thanks!

Yes, I can reproduce that same problem in newly created Third Person Template projects as well.

Crash Report window comes up after a while (~20 seconds).

I attached all 3 files.

Thank you for your quick response. Very positive thing how Epic treat their users. (good community, various helps and tutorials, detailed and understandable documentation, example projects and free contents, and of course Engine which is great and easy to use compared to others (and that now it’s free)) I know that this isn’t a place for this but I use UE4 for about a year and now I must tell it to you that what you are doing is fantastic. I think UE4 is best an indie developer could wish. Keep it up!



Thanks for encouragement, that’s always great to hear =)

Hm, this doesn’t look like any crashes we’re aware of. Would you mind uploading test project you made and post a download link for me? I want to see if this is something in your system or something in project. Thanks!

Of course I wouldn’t mind. Here is link:

This is Epic Third Person Template I newly created.

Maybe loading of available bones and sockets creates crash (if it doesn’t find them or something and keeps trying it again and again until it freezes engine), but maybe some other stuff.

If nothing helps is there any other way I could attach that camera to socket (maybe manually), or any other way I could do FPS/TPS toggle? Because that would be my goal.


Thanks! So this crash was happening when you clicked on Magnifying Glass in Parent Socket parameter of FPSCamera component? I opened up your project and didn’t have any problems with that, so I’m guessing problem lies with your version of editor.

First thing to try: go to Launcher, and in Library tab, select 4.8 slot and choose Verify. Then try again in a new project.

If Verifying engine install didn’t work, try this: here is a link to project you sent me, with Parent Socket assigned. Take a look at that and see if it still has that in place. If so, you might be able to work with that for now, though I’d still like to figure out what’s causing problem. Let me know what happens either way.

Next, see if same problem occurs for you in 4.9 Preview 2, if you have that available.

Yes problem occours exactly as you say in your first sentence.

Unfortunately I only have mobile internet and now they (T-home… I hate them) slowed it down to ~16 KB/s and it remains slow until turning day (10th day of each month). This speed is even not enough to launcher to be able to connect to your server. So for now update or verifying is impossible.

I downloaded file with my last fast megabytes and yes it’s still in place and I can use it but it isn’t my project file so unfortunately I can’t use it for anything.

I have a partner who maybe can attach camera to socket but if he has same problem could I ask you to do same thing you did with test project with my real project? If so I can only upload it in 10th of August. I’ll inform you about what happened.

Thank you so much

That wouldn’t be a problem, just send me a link to it via PM on forums:

Strange that your partner is experiencing same issue on his end, though. Makes me think this isn’t an engine install problem. Once you have better internet, try out Verify and 4.9 Preview and let me know what happens. Thanks!

Hey, just checking in to see if you’re able to check this in 4.9 Preview or send me project to fix up for you in meantime.

Hey Spear,

I haven’t heard back from you in a while, so I’m resolving this post for tracking purposes. Let me know if you’re still having trouble with this and if you’ve been able to test in 4.9 Preview yet. Thanks!
