Send to Unreal - Discussion - Arrayed static meshes and hierarchical/instanced static meshes

Open Feltehs opened this issue 1 year ago • 1 comments

Addon: Send To Unreal Description: It is common in archviz and other modelling techniques to take a complex mesh and instance it many times. This is possible in two ways inside Blender - array modifiers and alt+d (duplicate instance referencing same base mesh)

Meshes exported from Blender should maintain low polycounts even when used in large quantities (via arraying and instance referencing)

Workflow:

Blender:

  • Create a default cube
  • Add array modifier (relative offset -> 2 - No merge)
  • Alt+D to duplicate an instanced mesh and move 5 units away
  • Pipeline -> Export to Unreal

Unreal:

  • Current behaviour is to see two meshes produced - with two unique origin positions and 5 sets of polys in that mesh
  • Suggested new behaviour is to have a blueprint created including one mesh with a hierarchically instanced mesh in the relevant array positions [Open discussion point as to what outcome people would expect here]

This would be very useful indeed. I totally agree with the suggestion.
