Nanite Displacement Bounds Mismatch Causes Floating Terrain Artifacts on Landscape
UE - Rendering - Graphics Features - Nanite - Mar 19, 2026Summary When Nanite Tessellation (Nanite Displacement) is enabled on a Landscape in UE 5.7.3, scaling the Displacement value via Multiply nodes in the material graph causes floating terrain ghost a ...
Nanite Skeletal Mesh ignores Hidden Material Section flag
UE - Rendering - Graphics Features - Nanite - Mar 11, 2026Unlike non-Nanite Skeletal Meshes, Nanite-enabled Skeletal Meshes do not correctly respond to the Show flag passed via ShowMaterialSection(). Consequently, the Isolate checkbox for material slots in ...
Nanite culling breaks on scaled object with displacement when camera enters displacement area
UE - Rendering - Graphics Features - Nanite - Mar 9, 2026Nanite tessellation, only supports calculating displacement in local space and everything gets scaled with the object scale, which is often undesirable. If the camera enters inside the area allocate ...
STAT_StaticMeshTotalMemory increases after repeated loading and unloading of a level containing Nanite static meshes
UE - Rendering - Graphics Features - Nanite - Feb 26, 2026The issue appears to be caused by a mismatch in the value returned by GetResourceSizeBytes(EResourceSizeMode::Exclusive) between InitResources() and ReleaseResources(). At InitResources(), the repo ...
Nanite displacement issue when using along non-uniform scaling
UE - Rendering - Graphics Features - Nanite - Feb 26, 2026Nanite Tessellation displacement direction is incorrect for landscapes with non-uniform scales. It seems to use the normal from the unscaled landscape, which can result in the displacement causing t ...
Crash caused by a race condition in Nanite::DispatchBasePass()
UE - Rendering - Graphics Features - Nanite - Feb 25, 2026Nanite::BuildShadingCommands() launches two asynchronous tasks: ShadingCommands.SetupTask ShadingCommands.BuildCommandsTask BuildCommandsTask is responsible for modifying ShadingCommands.Commands ...
Distance Field Shadows do not work with Nanite meshes
UE - Rendering - Graphics Features - Nanite - Feb 16, 2026Nanite meshes only cast virtual shadow maps and do not cast any distance field shadows, regardless of the distance of the shadow casting mesh to the camera. ...
PlayerCollision visualization incorrect on LandscapeSplineMesh when Nanite is enabled
UE - Rendering - Graphics Features - Nanite - Dec 3, 2025From licensee: I’ve found an issue with the visualization of PlayerCollisions when using LandscapeSplineMesh with a mesh that has Nanite enabled. The Chaos collisions shown in the Chaos Visual Debu ...
Material picking of Nanite meshes with multiple sections not working
UE - Rendering - Graphics Features - Nanite - Nov 24, 2025Picking a material of a section of a Nanite enabled mesh will not work correctly, while the same picking logic works fine for non-Nanite meshes. On Nanite meshes, the reported section index seems to ...
Vertex color does not work on Skeletal Mesh with Nanite enabled
UE - Rendering - Graphics Features - Nanite - Oct 7, 2025Nanite enabled skeletal meshes don't work with materials containing a vertex color node. The vertex color material does work for non-Nanite skeletal meshes and Nanite-enabled static meshes. ...
