Rvt blend gets broken when you duplicate the ExampleOpenLandMap

[Daniel Elebash]

Open Land v 1.13.0

Steps to reproduce

1. Right click on Maps>ExampleOpenLandMap>Select Duplicate
2. Open your duplicate map
3. Select SM_Rock5 in your world outline and press f key to focus on that object

You will notice the rvt sand blend is not working

I just checked that. That's because Unreal Engine removes virtual textures from the Runtime Virtual Texture Volumes when duplicating.
Once you applied them again, it'll work fine as expected.
