Company of Heroes 3: Modding Details Revealed – IGN First

To have it ready for launch, the initial release of the Essence Editor will be somewhat limited. Notably, custom unit skins and meshes won't be supported just yet – though you can mix and match different clothing items and accessories from the units already in Company of Heroes 3 to create custom kits.

So what we initially thought would be super important, for example asset swaps or making skins, was actually lower on the priority list. And what was higher was being able to do tuning, to be able to do their own modes, scripting, and also their own maps."

One of the key pieces of this implementation is a type of all-in one
