I’m doing a caves for my terrain. I have 2 solution, but none are good enough  
_Caves are just a simple shapes - later I’m going to improve_

**The problem is - to merge a landscape and a caves**  
Solution I know are  
• using UE’s Landscape System  
• and without

## **Single-mesh terrain**

Caves - via mesh boolean

+clean merge line  
+simple workflow  
-is not compatible with UE Landscape System

## **UE Landscape using Visibility Mask**

It also affects collision (is enterable hole)  
Caves are sepatate mesh

+UE Landscape System  
-merge line are awful

**Overall, Lanscape System gives to much out of a box, so I can simply drop it, and switch to a simple mesh**

👎Seems only way for now - to fill a gaps with other meshes  
👎Blend a landscape with a mesh - is also not a case. It just a visual blend. Mesh accurately placed on atop of Landscape

**So, let me know, if you have a solution/idea - how to nicely merge a Landscape with a cave mesh**
