The total number of components that will be created for your Landscape.Ĭreates your Landscape in the world using the settings you specified.įor this example, we are going to leave all of the Landscape settings at their default values that are listed below.Landscape Auto Material is a flexible autopainting material for Unreal Engine 4 Landscape component. The number of vertices your Landscape is using. Going over this cap could result in performance issues with the Landscape. This value is capped at 32 x 32 since each component has a CPU cost associated with it. Sets the size of your landscape along with Section Size. These issues could be even worse on mobile devices because of the limited amount of draw calls you can have due to hardware limitations.
This could be especially prevalent when using very large areas of Landscape. However, you might run into issues with the Landscape rendering too many vertices at once. With a larger section size, you get the added benefit of reduced CPU calculation time. One component could have 2 x 2 sections which means that it is possible that one component could be rendering four different LOD's at once. Each section is the basic unit for the Landscape LOD.
If you want to have a large Landscape, you will need to use a larger section size, since using a smaller section size and then scaling the Landscape will increase the cost on the CPU. Larger sizes allow for fewer components and is less costly on the CPU. Smaller sections allow the Landscape to LOD sections more aggressively but at a higher CPU cost. Landscapes use Section Size for LOD and Culling.
