I’ve found out that if I want to blend nanite megascans with landscape I need to use virtual textures.
Problem is that when I import anything from Quixel Bridge, if the “Virtual Texture Stream” option is enabled in its textures than the material will have really poor quality. On this issue I’ve found out that the solution is to disable “Virtual Texture Stream” option and then everything looks like it should.
The issue is that how can I make materials blend into landscape if “Virtual Texture Stream” breaks the quality?
