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"

Trackpad two finger drag remapped in 4.3/Not working in windows?

In the recent 4.3 update my trackpad on my macbook pro started behaving differently in UE4 (OSX version). Previously it would operate as a right click drag, rotating the view and so forth. Since the update it counts as a middle click drag, causing the view to pan.

Also while running UE4 in windows via bootcamp right click dragging does not work at all.

In practical terms this makes UE4 unusable without plugging in a mouse, which is a real pain and impractical at times when I want to get something done quickly.

This is a pretty major workflow issue for me now. Is there a setting I can use to change this behaviour in OSX and also to fix the trackpad input for windows?

Hey Cratesmith,

In 4.3, two-finger dragging in the viewport should rotate the view, and two-finger + click dragging should pan. It should match what occurs with a mouse. There was a change in how the trackpad responds within the EventGraph for sub-editors, but that shouldn't affect your viewport navigation.

What OSX version are you using? What are your system specs? Does this occur in every project, including a new project?

Running in Bootcamp may not be officially supported by us. I don't know whether Windows reads gestures on a Mac trackpad through Bootcamp. I'll double check with the developers and let you know, but that may just not be something you can do.

Have you installed this for your Mac so you can use gestures in Windows?

Hey all,

We haven't heard from you in awhile, so I'm going to mark this post as resolved for tracking purposes. If the issue still occurs for you in 4.3, please respond to the questions I asked above. Thanks!

Sorry to revive a long resolved topic but just wanted to jump in and confirm that two-finger click drag to pan does NOT work in 4.7 under the latest Bootcamp drivers and Windows 8.1

While I understand us bootcamp users are very much a niche user group, it'd be nice to not have to carry around a mouse with our Macbooks to do anything involving a Blueprint window.

Note I have tried disabling two-finger secondary click and had no luck.

Hi JonTerp,

Only a few gestures are supported in Boot Camp. Which are you trying to use? If you click with 1 finger and then place a second finger down, you should be able to pan the viewport that way, but if you place both fingers down at once it won't work (it'll think you're using the secondary click).
