Hey, thanks SaOk.
Are you seeing any warnings/errors in the output logs? Is this the marketplace version or one of the previous downloads?
[Marketplace Version] Infinite Manager crash fix
I discovered that the marketplace version has a bug for the Infinite manager where it crashes the sample map. Those who need an immediate fix can download the fixed BTTask_FlyTo.cpp and paste it inside the DonAINavigation\Source\DonAINavigation\Private\BehaviorTree folder (marketplace plugins are installed inside *<Your4.15EngineDir>\Engine\Plugins\Marketplace\i]) You can also use any of the previous plugin downloads on the website although this one has some important bugfixes (apart from this bug that crept in!)[/spoiler]
@SaOk - I’m not sure this will help you as you’re not seeing any crash in the first place so your issue may lie further upstream.
Your other questions:
No special steps should be necessary. Remove the previous manager, add the unbound manager (DonNavigationManagerUnbound) and configure the voxel size. You don’t even need to change the grid size/etc because it’s not used. If the pawn is not moving, check the output logs for errors/warnings.
The normal manager should not be crashing. Your output log (<project>/saved/logs/<projectname>.log) may have information on what triggered the crash that I can use to diagnose this.
It takes a bit of trial and error to get the setup right; VoxelSize and AutoCorrectionGuessList in particular. The output log will tell you exactly why a location was found unsuitable. If you share that snippet and/or a screenshot of the unsuitable location it will be possible to deduce what happened.
This is more likely due to large memory consumption in Editor/Debug builds than any of the other issues. If your X/Y/Z grid was set to a somewhat high value then the memory allocated shoots up quickly and when you stop playing it takes a while to release all those resources. Packaged builds tend to consume much less.
Hope this helped!
