In the KiteDemo folder that is included in the Open World Demo Collection by Epic Games, I found extra materials that seemed far more ideal for what I wanted. So I decided to add extra layers and remove the grass.
Grey squares were appearing after painting several layers and were not disappearing over time. or after building and running play. I figured it may have been to do with adding too many layers and started to search for solutions.
On this thread, an unknown user posted explaining select the layers and set the Sampler Source to Shared: Wrap.
By using this, the grey blocks disappear and the materials are working much better. It seems we should be using shared mode once we are reaching 16+ textures, and there is no loss of quality.
I tried to search for an explanation for what Shared: Wrap setting actually does. I could not actually find a clear response that made great sense, other than we should use this setting once we are using 16+ textures.
Using a combination of textures blended together, I am beginning to see a darker and more realistic effect on the terrain. Overall, it is a huge improvement in comparison to the previous version of the terrain. It is currently still very bare and the grey areas have diagonal stripes through them and a use of different texture may be required for a realistic effect.
