Hello,
I hope some one can answer this question for me. With 4.22 they changed the engine architecture to “Auto Instance Static Meshes”, Would there be any reason to manually use the Instanced or Hierarchical Static Meshes?
I did some testing with again Static Mesh vs. Instanced vs. Hierarchical Static Meshes and could not tell a difference in performance between them. If anything, just using regular static meshes was better performance.
I would much rather just use a regular static mesh than having to setup Instanced or Hierarchical Static Meshes.
Thank you,
John
Results of a quick test:
Added 500 boxes in 3 different ways.
DrawPrimitiveCalls:
Actor BP= 880
Static Mesh Component = 447
HISM = 270
Memory and texture was about the same. The static mesh boxes was almost 5 times more triangles :0
I’d say no for C++ but yes for Blueprints.
I switched my C++ architecture to use UInstancedStaticMeshComponent over UStaticMeshComponent and reduced my draw calls from 36,000 to about 200.
This reddit post leads me to believe that blueprints might work differently: Reddit - Dive into anything
I’m running version 4.24.1-10757647+++UE4+Release-4.24.
