Landscape textures acting funny

So here’s my problem.Up until I selected only painting for my landscape, the entire landscape loaded up properly.Now, when I selected different textures for grass and gravel,the landscape looks completely black from up top.When I zoom in to get a close up view it loads up in a circle around my field of vision.But the far off area still looks black. Attaching a screenshot for example. I created a custom landscape material with 3 layers for dirt,grass and snow. While the dirt and grass are texture samples from the starter content gravel and grass ,the snow is a vector parameter with a greyish paint.

This is what the lanscape looks like from up top.

And this is what it looks like from up close, at ground level. From the ground level the textures load up fine but in a specific radius of sorts as you can see. Why don’t the texture for the entire landscape load up properly? The paint still loads up properly as you can see.
Here’s my blueprint:
