Built version of a project doesn't work while viewport does.

I’m trying to build a model viewer with orbiting and zooming around an object. In the viewport, the project runs flawlessly but when I build it, some functions don’t run/get called at all.

for example:


r/UnrealEngine5 - Calling Zoom funciton when scrolling.

Calling Zoom funciton when scrolling.

The upper function doesn’t get called at all in the built version but works in the viewport. The axis values work as they should in both versions in this case.

Another example:


r/UnrealEngine5 - getting mouse position

getting mouse position

In the viewport I get correct values from these nodes, in the build version, I always get 0.0.


r/UnrealEngine5 - this is a weird one

this is a weird one

This prints “True” while in viewport mode but prints “False” when running a built version…

I need some help, I’m losing it ^^
