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"

Nav mesh is fragmented in Published Game 4.21

So when testing my plugin demo it seems that the nav is not fully generating in published builds.

Hello,

We've recently made a switch to a new bug reporting method using a more structured form. Please visit the link below for more details and report the issue using the new Bug Submission Form. Feel free to continue to use this thread for community discussion around the issue.

Thanks

Hey Shoiko, have you made any progress on this, or have a UE bug ticket yet? I'm having the same problem. Do your fragments directly relate to the 'show tiles' debug on the navmesh in editor? My project currently has 40 minute build times, so iterative testing small nav tweaks is a pain.

Hey Kevin,

I'm not sure when this fix will be ported over to Release but this issue has been addressed in our latest internal build. You can find that build on our GitHub Master branch if you use or are familiar with Source builds.

Thanks, Trey

Can we know which files has been modified for the fix? So we can do a dif

I don't understand why this fix is not ported in release, it's game breaking. @jimsnomis did you find the fix?

@Adrien nope waiting for the next point release.

I just Tested 4.21.1 and Fix is not there. After building a game for Android Nav Mesh is still fragmented.

Do you have an Issue Tracker ID for that bug?

avatar image jimsnomis Dec 08 '18 at 02:29 PM

@Shoiko - Do you have the commit hash? - would be handy for this to cherry pick the fix.

avatar image eudrea Dec 11 '18 at 02:23 PM

The issue is still present in 4.21.1 build. Not sure the fix is suppose to address this issue but this hasn't been a problem with 4.19 builds so is something that happened after.

avatar image Shoiko Dec 19 '18 at 10:46 PM

They said its fixed on the head branch no clue when that will be released i dont really download code from the source. I hope they push it out soon.

avatar image Adrien Jan 10 '19 at 12:36 AM

@Shoiko @Positivity @eudrea The target fix is now 4.22 in UE-67512, this mean we have to wait a other couple of month to get the fix...

Why does the fix is shared only for UDN ? (https://udn.unrealengine.com/storage/attachments/330558-p4diffs.zip)

Can someone share the solution here please ?

avatar image eudrea Jan 10 '19 at 12:32 PM

I can say it works with a source built from the Master Branch so the fix is in there

avatar image Adrien Jan 10 '19 at 06:30 PM

@eudrea We are based on the release branch. We don't know how to switch branch while keeping our local changes.

@adrien haven't had the time to trawl through the commit history which is what I would do to find the fix. I'm waiting for an official release. There's an UE issue submitted here https://issues.unrealengine.com/issue/UE-67512 but the linked files don't exist.

avatar image Positivity Dec 20 '18 at 07:08 PM

Linked files are in UDN ,, what is Similar Forum or Answer Hub only for Serious Developers or License holders. It looks like ppl start to point to the problem there too .. however, I would not wait for Fix this year .. maybe only if a miracle happens and there is new engine Version Right before the new year.

avatar image jimsnomis Dec 20 '18 at 07:50 PM

Thanks for the info I had no idea there was a separate area for licencees. I've written to Santa Claus to ask for a fix for Christmas.

@Positivity Thank for calling alot of us non-Serious Developers... It's a game-breaking issue for more than one month, no hot-fix, no public sharing of solution ?

@eudrea We use the release branch with some local modifications, we don't know how to switch branch while keeping our changes.
