I'd prefer to only have concrete in the logistics area and not in the construction area. Does it do this?

The mod covers all of the way out to the construction radius. I may look into an option to support limiting the radius.

Have you looked into this?

Concreep now supports configurable range.

i cant go above 100 tiles? its less than usefull now, it doesnt even go up to the construction range?

i fixed it. in settings.lua
type = "int-setting",
name = "concreep range",
setting_type = "runtime-global",
default_value = 1000,
minimum_value = 0,
maximum_value = 10000,
order = "01"

Concreep range is given in a percentage. 100 means 100% of the construction range.

What would be the range of just orange area? Is it 50?

The Range of the base game's Roboport Logistics (orange area) would be 45.4545...% of the Construction (green area) range.
I would recommend making the setting 45 (or 46 if its 1 tile short) if you want it to cover just the Logistics range (orange area).
