Sometimes I need to render outdoor scenes in Keyshot, for a building. In order to save time, I used the picture directly in the background. At this time, the place where the building is connected to the ground is not natural enough, so I added a displacement map to the ground. I hope that the building is embedded on the sand and stone ground. It should be similar to the Cutaway material to form a building. The appearance of sinking into the ground.
Now, when the item passes through the ground, it will become black and lose its texture.
