If I have large image files in my shader setup, are they loaded before they are Enabled? If so is there a simple way to keep them out until I need them? I have a large project file on a large terrain and want to reduce my memory overhead from distant sections while I am clear across the map.
Why don't you test this?
For objects/populations I know that when I save the .tgd with objects/pops disabled that they won't be loaded upon opening the .tgd.
Once I activate the node it will load into memory.
