Open world demo what went wrong here?(pics)

So I’ve followed these steps* but when I got to step four and tried to load my meshes it came out grey…?
Anyone know whats going on here? Maybe I have to follow dif steps as its 4.16 instead of 4.8?

My bad wrong link, Using this https://docs.unrealengine.com/latest/INT/Engine/OpenWorldTools/Grass/QuickStart/4/index.html

I’m not 100% sure, because I thought they fixed it already. However, instead of using the grass brush, can you first click on your ground material and paint the whole landscape with that material? (make sure to increase the brush size and brush intensity to max)

Okay, First of all thanks so much taking your time to help me.
So you want me to use the Landscape>Paintbrush?
Basically rather than filling in the ground with by dragging and dropping the texture over, use that paintbrush to paint it over the landscape? What should I set the base texture as if so?

The picture in step three might be misleading. If you still get the Layers showed in step four, you can continue, pressing the +, adding weight-blended layer, assigning the created layerinfo and then you select the rock layer and paint over the whole landscape, so you have your ground. After that, you should be able to paint your grass patches.

Thanks man you are the best.
