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"

[Request] Can we get better trackpad navigation within the graph view of blueprints?

Hi all

I use a MacBook Pro for all my UE4 needs. Even when using an external monitor I use a magic trackpad since I get RSI from using a mouse. In my journey with UE4, I've found that it works really well with trackpads most of the time. The main area that I would rate as painful to me is the graph view which really doesn't work well with trackpads (on Mac).

The usual two-finger touch motion that should scroll a view around simply zooms in and out (it works like mouse wheel scrolling) and it doesn't support the standard pinch-style zooming either, in short, there doesn't appear to be a way to logically move the view around using a trackpad. The orthographic views in the editor (as an example) handle the trackpad motions correctly - scrolling when you use a two finger drag, and zooming in/out with pinches. Ideally the graph view (for materials and blueprint editing) should operate the same way.

Both Cascade and Matinee don't handle these inputs correctly either, and should ideally work the same as the orthographic view as well, but I have not used these editors much myself, so not sure how much of a problem it actually is, a quick play with the UI suggests Matinee isn't too bad since it has scrollbars you can use to move the track view around, but couldn't really figure out cascade at a glance.

So I guess I have three questions: 1) Is there a good alternative I can use to move the graph view around that does not require a physical mouse? I've personally been using box selection and scrolling to the edge of the graph which does make it move in that direction, it gets the job done, but it's a pretty clunky way to work. 2) Could you guys please make the graph view handle trackpad inputs correctly? (basically mirroring what it does on the orthographic views would be perfect as that handles it correctly). <-- this is my high priority request :) 3) As a bonus, if you guys can do it, can you make Cascade and Matinee handle trackpad navigation correctly as well?

Thanks guys!

I can't help with question 1, sorry. Maybe someone else will have some idea. But I can answer questions 2 and 3 - we do plan to add proper trackpad support to other parts of editor, and soon. I don't know when exactly, though.

That's great to know. And thanks, I really appreciate the awesome support the engine is getting on Mac now.
