just like the title says.

i want to be able to edit and enable a grading system like the one used in the ADD004 lifebars .
i am currently making a screenpack. its still a WIP and far away from completed but since im going through all this effort in making it why not learn how to make a lifebar to go along with it.

here is an old youtube video of what i have made currently.



any help would be great if you guys would be so kind to point me towards a tutorial of some sorts
