Hi , if you like to insert a building in a existing world, this can be verry hard, because you need a flat surface to build on.

Now you guys have this two verry good Prefabs:

{323D779591F59437}Prefabs/Structures/Walls/Concrete/ConcreteRetainingWall_02/ConcreteRetainingWall_02_8m_grass.et
{B1D7DA05DE5D73F4}Prefabs/Structures/Walls/Concrete/ConcreteRetainingWall_02/ConcreteRetainingWall_02_V1_8m_grass.et

While placing one of them inside world and scale it tho the size you need, you can build on it. There is just one problem: The terrain does not have a collision.

So, if any character is walking on them, they will clip inside the modified terrain, like 40 - 50 cm.

Can you guys please check if you can fix this? Thanks
