[4.11 preview 2] Crash on baking Landscape Textures

I have not edited any engine folder content for this project. It will bake some then crash after it bakes about 100 or so out. Then crash report throws this error.

Access violation - code c0000005 (first/second chance not available)

Let me know if you need anymore information thanks.

Hi Sir Jecht -

Thank you for your report. A colleague or myself will be in touch with you as soon as we are able to reproduce this issue. In the meantime, if you can please make sure that you have submitted your crash with crash reporter and posted your Machine ID here.

Thank You

Eric Ketchum

Hi Sir Jecht,

We’ve not heard back from you yet, are you able to post your Machine ID from the Crash Reporter window and do you have any steps that can help us reproduce this issue on our end?

Some details about your project, like the size of the map you’re building lighting for, the call stack mentions Light Propagation Volumes (LPV) so if you’ve got this enabled it would be helpful to know for sure, along with any settings that have been set for the lights you’re using.

Thank you!

Tim

Hi Tim & Eric,

Sorry for the late response. I have been out of office for the past few days and was unable to get the ID’s off the machine in time.

Also we are breaking this out in passes for a VFX movie production so if this breaks it is only in this project that the file is breaking our other projects are working fine. And since the background is out of focus for all of these shots we just ended up doing a plane replacement so this issue isn’t pressing. Just wanted to give you a heads up encase it was plaguing our other projects which wasn’t the case.

Thanks,

Sir Jecht

Thanks for getting back to me, Sir Jecht.

At the moment, I’ve not been able to reproduce the crash, and I don’t see this specific crash linked in your original post listed in our crash reported. I tried a couple of different things to see if I could reproduce, but I didn’t have any luck.

Since you have a workaround for the moment and it’s only happening in this project that you’ve found I’ll mark this resolved for the moment. If you have any additional steps to reproduce the crash I can look into it.

Thank you for taking the time to report the crash!

Tim
