[Solved] Teleporter trigger volumes not working in specific locations of a level

Hi everyone.

I have a strange problem using Unreal 4.9.2 on a Mac. I am at the stage of prototyping and I am using simple teleporters to test out the layout of my stages. Here is the thing. Some teleporters simply won’t work, they won’t even register an overlap and if they do they don’t fire anything.

I use a blueprint for the teleporters, in there I have a particle and a collision box. I use two of those, HG_Portal_A and HG_Portal_B. The traffic is one way from A to B.

I use the blueprint as shown in the image, in my Level Blueprint.

I place one pair (A & B) then another and they work perfect, I place a third… fine, I place a forth and it will not work, I place a fith it works, a sixth it works, seventh wont work etc, etc.

What I have tried and didn’t work.

I tried switching game modes, going from 1st to 3rd.
Tried reloading the level, nothing.
Tried restarting Unreal.
Tried veryfing Unreal.
Redownloaded it.
Replaced the teleporters.
Replicated the procedure with just trigger volumes and no blueprint.
Used Breakpoints and Printed a string after each step. The strings got printed but no teleportation.
Sometimes it goes straight to isTeleporting (True) skipping the isTeleporting (False) path of the branch, even if the isTeleporting was set as (False) At Begin Play. In one level the first teleporter I insterted didn’t work.

Some trigger volumes refuse to work at specific locations and this is happening all over my project.

I don’t know if it helps but two of the teleporters that failed in my first level.
did so around that Location.X.

Any help is appreciated. Thank you.

Update: Dec 6

I tried something else today in my first level. I moved a pair of teleporters that work (A & B) to the location of the teleporters that don’t work (C & D). A & B stopped working too. I moved A & B back to their original location and the worked just fine again. See image below.

SOLUTION

It turns out that IF a single pixel of the destination BP’s Tigger Volume is beneath the surface, the game will not spawn you there. That is why the origin trigger box acts weird. I hope this helps anyone playing around with teleporters.
