Any chance to "fix" this so that it works in 2018+
The drop-down list has the option to select values that don't work, due to a text-issue?
("10
20
30
40
50
60
70
80
90")
10 and 90 don't work, but they are "doing something", which can be undone. However, if you don't "undo", it can break the model.
Seems like it is just a simple format issue for the list. (Apparently reading the value from the list, instead of reading the values from an INDEX of a LIST. So, the odd text in the first and last values sort-of break the script.)
Personally... I would like to see a slider with 1%, 2% or 5% increments. Maybe also an option to just do a triangulation first, as 0%... Something that would yield some "corrective action", before reducing polygons, if needed. (I don't always agree with the way it triangulates some surfaces, as it doesn't favor neat reductions. Being able to see the way it is going to divide it, before reducing it, allows for some manual triangulation of those potential troubled parts.)
Another option would be to subdivide first... (Creating a smoother potential which to begin a more accurate reduction that may retain those micro-details more, without harming large flat surfaces as much.)
