For the Rocks and Trees I wanted a material that could adapt to the environment and the color of the landscape. Using RVTs (Runtime Virtual Textures) for color and height, Unreal Engine can define where and wich color will be used in that object. The good part of using a material like this is that we can move the objects around the landscape and the object colors adapt to the landscape. This type of material also helps the integration of the object in the scenery, which is why i decide to go with this type of workflow and not just simply texturing the objects alone.

I made the two materials using the same base material with a lot of parameters that i could tweak and change. With this commands i can control how much the material affects the object.

This allows me to create smoother transitions of colors and helps giving personality to the objects, as well as making them more unique, i can use diferent effects on different trees, which will make them fell different even though they are the same.
