Summary

Pathfinding is now completely broken!

Steps to Reproduce

Spawn an NPC (I’ve tried both Guards & Custom Types) → use Verse and NavigateTo() a very specfic path (in my case a simple path with ONLY 90 degree turns) → try it out

Expected Result

The character actually goes to the specified locations. This worked before the recent update. Something in the running/walking conditions must have gone wrong, but changing Movement Type doesn’t seem to change anything.

Observed Result

NPC walks into random walls and it seems like it doesn’t take the points into account at all - or maybe it tries to use some weird path, that makes no sense in my case.

Additional Notes

As stated earlier, my path is really simple (Path - Album on Imgur). It’s just creative props, which are used to configure the path, which only consists of 90 degree turns. The path is surrounded by barrier devices, but that probably doesn’t have an impact? Worked a week ago :confused:

Really happy with the extra flexibility of the NPC’s though, just needs some fixing! (:

Think I finally figured it out…

Turns out, the new update is even better than expected - and it was just me being a bit narrow-minded. Prior to the new update, I used a ?ReachRadius of 0.1 in the NavigateTo. I’m presuming this is in centimeters, as that’s the default metric of UE.

What I didn’t think about, is how little 0.1 cm actually is. I’ve bumped it up to 20 now and it seems to have fixed it (although there are still some more instabilities, but that might again be my mistake).
