Is it possible or is there some workaround for blueprints?
Aaand still want this one 
As this thread is two years old and you are now a moderator i assume you have already figured out a workaround, but for those who have not:
-Multiple arrays of equal length of different types. All you need is the index to get from both at the same spot.
-An array of structures where the structure includes the two (or more) data types you need.
It’s been a couple weeks since the last post on here but.
“Type ‘TMap’ is not supported by blueprint.”
We are still interested! (I lack the skills necessary to actually make it happen and am still learning or i would actually work toward this my self.)
Sorry for resurrecting this ancient thread but have there been any updates? I’ve been trying to find tuples or dictionary features in blueprint and found this (and few other similar threads).
https://docs.unrealengine.com/en-us/Engine/Blueprints/UserGuide/Maps You can use TMaps in Blueprints as of 4.15
