This step can be skipped entirely if you are not planning on using one of the Splatmap Baked or RVT Performance Presets (preset 1 – 4) on your new map or if you’re not wanting to utilize Runtime Virtual Texturing in your project.

These steps can be seen as slightly advanced, though once you do them (and you only have to do them once per new map), they’re pretty simple to perform again.

This process only takes about one to two minutes to perform, start to finish and is standard set up for any new project using Runtime Virtual Texturing.

As an additional note Runtime Virtual Texturing does not currently work on mobile platforms as of UE 4.25 and 4.26 and using it with terrains larger than 4k in resolution will cause the Runtime Virtual Texture to be stretched by too much because RVT is basically baking the entire terrain material into one giant texture.

With all of that said, this is how to fully enable its use on your own terrain in order to get the performance benefits from it. In this video I’ll go over both RVT blending and how to first setup RVT to work with your world.
