Currently A3 has no way to define Custom Object Map icon.
we have to use https://community.bistudio.com/wiki/Arma_3:_Named_Properties#map
list one ones provided this is fine unless we need a obj that is no where near scope of these objs

for example i was trying to add a custom hedgehog icon
If setting a model map class to this and binning terrain Icon will not show even though config view Cleary shows rscmap is updated.

I would sujest either adding some extra map icons eg hedgehog
Or opening up this to allow retex or extra classes added.

class RscMapControl
{
	class hedgehog
	{
		color[] = {0,0.9,0,1};
		icon = "\jones_surfaces\map_hedgehog_ca.paa";
		size = 16;
		importance = "0.7 * 16 * 0.05";
		coefMin = 0.25;
		coefMax = 4;
	};
};
class RscMiniMap
{
					class hedgehog//: hedgehog
					{
						color[] = {0.5,0.5,0.5,1};
						size = 14;
						importance = "1.5 * 14 * 0.05";
						coefMin = 0.25;
						coefMax = 4;
					};
};
