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"

Crash with Vive and Sequencer

Two things that I discovered. First, and I think this is a know issue: When the Vive is connected, you can only have one instance of the editor running at a time. If you open a different project, it will shut the first one down, without notice, and unsaved changes are lost.

The second issue I encountered was with a project not involving VR, but with the headset connected to the computer, as soon as I tried to scrub in a sequence, the editor would crash.

Disconnecting the headset resolved the problem.

The above issues happened with both 4.11 and 4.12



Product Version: UE 4.11

Hello SterlingY,

You are correct, the first issue is a known issue (UE-29485) that has been reported and submitted to the developers for further consideration. After reading over the report, it appears that this issue is caused by Steam VR forcing the process to close. This means that a solution for this issue is most likely out of our hands. As for the second issue, I was unable to reproduce this issue on our end. I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in clean project?

  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?

  3. Could you provide screen shots of how you have setup your sequencer?

I prepared myself for the long haul to try and replicate in a blank project, but it's quite simple.

Vive is connected and SteamVR is off

Create blank project imported animated character and added to level(probably not required) Created sequence Added above character to sequence Added Shot Track Added Camera to level Added above camera TO shot track (BOOM)

In my case with my project, I believe the crash occurs simply because I already have cameras in the sequence.

Let me know if there are other questions

Good luck!
