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"

ARkit Object Scanning: Is AR Session Type Supported: False

Hello, I'll try to be succinct.

I have an Ipad Pro 12.9" running iOS 12.1.3, from both UE4 and Apple literature this should be compatible with ARkit and the 'Object Scanning' AR Session Type in UE4.

I am working on windows but using remote build via a mac mini running Mojave 10.14.3 and xcode 10.1. I have also tried launching the project directly from the mac mini onto the ipad with the same results. The mac mini is an older model, 2012, but the software is all up to date.

Would packaging the project rather than launching directly from UE4 make much difference? It hasn't seemed to matter before. I have already had success running the 'world' AR session and some image recognition so I know that it certain aspects of the ARkit are functioning properly.

I'm not entirely sure how to move forward. The ambition is to generate candidate objects for other apps, but when using the 'get AR Candidate Object' node the app crashes. I am assuming that it is something to do with the app not supporting the AR Session type for now. I have a basic UI which works for defining the capture extent.

Any suggestions?

Product Version: UE 4.21

Running into a similar issue. Also working on PC and deploying through a remote macbook.

Interestingly enough, both Object Scanning mode and Image scanning mode both return "False" when I query the 'is session type supported' function, however, Image scanning mode certainly works, so I dont know if the return is false and the session type works, or vice versa.

One thing I DID discover...

I was only able to get a slice of points from a point cloud using the "get points in box" function after I pinned it to the environment. All of my attempts before that returned 0. Not sure how helpful this, but at least it's showing that there's a way to ID and isolate a sub section of points.
