Enable post-process error

Development Programming & Scripting Blueprint

Hi,

In my game i have a zone where i use a post process component to invert the colors.
The functionality is in there and works perfect however, when i exit play i get a warning message but i don’t understand what it means. It talks about the construction script but i didn’t even touch the construction in this blueprint and it says “accessed none” what’s that?
THe strange thing is that i aleady used the same thing for the pause menu without error, i don’t know what’s different about this that it gives an error

(DangerColor is the name of the post process variable)

I believe usually it just means that the variable returned nothing when referenced (if it hasn’t been set yet or on play end). Try putting an ‘Isvalid’ node in there before you reference Danger color.

i.e. event actor end overlap > isvalid > set danger color enabled false> etc.
and
event actor begin overlap > branch > isvalid > set danger color enabled true > etc.

Unfortunately I’m not sure why it is referencing the construction script though. Hope this helps regardless!
