Static Mesh Assets Codec

PopcornFX can directly use Static Mesh assets to enable features like Sampler Mesh sampling, or static mesh fast collisions etc...

PopcornFX needs to build and save cache data along side Static Meshes in order to accelerate PopcornFX mesh features.

Cache Data

Auto build

When needed, a popup should ask you to build/rebuild the StaticMesh datas for PopcornFX.

But you may need to rebuild the cache manually in some cases


Manual Settings

The PopcornFX Static Mesh cache is located in the User Data of StaticMeshes.


  • Static Mesh LOD: the LOD level to use for PopcornFX.
  • Merge Static Mesh Sections: if enabled, PopcornFX will cache all sections into a single one. If disabled, the sections will be the SubMeshes for PopcornFX.
  • Editor Reimport: convenience button to rebuild the cache data
