How to match Landscape and Mesh material size?

I’m trying to insert a mesh seamlessly in to landscape. The trouble is, i can’t get the Materials to match in size.
I’ve understood that it is not possible to paint Landscape Materials to a mesh. I tried to use a TextureCoord node and none of the UV Tiling values gave any result.

-Do you get the same result when you use a landscape coordinate node?
-just set up a scale parameter (texture coordinate + scalar parmeter connected with a multiply) and then try to get the perfect value (when you use material instance constants you can see the changes in realtime) :slight_smile:

Here is my material. Did i understood correctly what you meant?
Changing Scalar Value makes the material glow like bronze and TextureCoordinate doesn’t change anything either. I tried LandscapeCoordinate too, with same value as on the LandscapeMaterial, but nothing happened.

You will have to add a names to your parameters - close the material - do a right click on the material - create material instance constant - apply the MIC to your mesh - open the MIC - now you can change the parameter value + you will see the changes :slight_smile:

Also make sure to:
-connect the multiply with the base and normal map
-choose different names for your parameters (atm you change everything, so the size - metallic - roughness)

It’s working! Lots of good information again. Thanks a lot, ! :slight_smile:

I’d make the mesh fade out onto the landscape to make the transition much smoother.

This would be an excellent use case for world space UV coordinates. There’s a material function for that.

Thanks for answering and sorry it took me a long time to answer!

Is it WorldPosition you mean, that would achieve this kind of fading? There’s an example of this here: https://docs.unrealengine/latest/INT/Engine/Rendering/Materials/ExpressionReference/Coordinates/index.html
Althou, i don’t understand how to use it with the example.
