Thanks for your reply. In my situations plugins of a bundle sometimes depend on another. For example a code plugin might rely on a plugin providing a math library. This is I suppose similar to what I see in that model bundel assuming that they use a shared material / texture setup from some sort of core dependency. This makes me wonder how the marketplace handels this.
There is a new Humble Bundle of interest to game developers, the Unreal Engine Mega Pack Humble Bundle. This bundle contains a wide variety of very high quality 3D assets for 3D environments from Hivemind. The assets are redeemed on the Unreal Engine marketplace via the Epic Game Launcher. While this is a UE 5/5.1/5.2 focused bundle, these assets can be exported with relative ease for use with Godot, Unity or Blender as shown in this guide.
