Description

Something is rendering incorrectly about hierarchical instanced static meshes on vulkan mobile. If the project uses GPUScene, instead of using HISM for manual instancing, and relying on GPUScene for auto-instancing would be a suggested workaround.

Steps to Reproduce
  1. Open [Link Removed]
  2. Select "BP_BritishMuseum_TranseptLargeWall_Instances" in the outliner
  3. Observe the associated meshes

  4. From the settings drop down, set preview rendering level to Android Vulkan
  5. Observe that the same meshes look incorrect
