Problem description:

So I made a minimap system that grabs any type of atom I need - grabs a visual using the image proc, uses transform to shrink it, and then adds it to a "minimap" object's overlays. Works good CPU ussage wise and such but I noticed if I have too many overlays (atoms being rendered) the display/render speed seems to take a bit of a hit. (And, at least visually, it lags)

The map is only rendered once and the object is kept in a list for later reference - so it's not being rendered every second or something insane.

Is there any way to merge images together like icons can use Blend()? Would using icons in this way be equally effective CPU wise since the map is one time rendered?

My alternative approach that I haven't tried yet is to use icons, abusing blank icons and Scale() to make massive icons and shifting the thing into pixel place before Blending it together.


Any ideas or suggestions to alternatives?
