Crash when using both tessellation and virtual texture on a landscape material

When a landscape is set up to use runtime virtual texturing. If it uses a material that writes to a runtime virtual texture and has tessellation enabled. Then we see a crash and the log reports: ...

Large Landscapes cause long PIE start time delays

These delays appear with large Landscapes (for example 8029 x 8029) . The delays only start occurring after the level is saved and reopened. After which PIE start times will be 5 to 15 times longer ...

Origin Shifting Landscape crashes Render Thread

Shifting the world origin with a landscape in the level causes a crash in the render thread. This does not crash in 4.23.1 (CL-9631420). This was reported and tested in 4.24.1 (CL-10757647) and rep ...

Licensee says that adding multiple InstancedStaticMeshComponent instances can be very slow (main bottleneck being the physics building). I think there's a good case for a method something like:   ...

Simple collision Landscape returns incorrect physical material

When a landscape uses simple collision, the returned physical material can be mismatched. This seems to be a result of ConvertHeightfieldDataForPhysx within ULandscapeHeightfieldCollisionComponent: ...
