Realtime Mesh Component is a high-performance, fully dynamic mesh component for

Unreal Engine, built for geometry that can't be packaged as static content: meshes

created at runtime, loaded from user files, procedurally generated, or continuously

modified. It scales from a single hand-authored triangle to full procedural worlds.

RMC is faster and more memory-efficient than ProceduralMeshComponent, and ships

migration helpers so existing PMC code ports with minimal changes.

Features:

Full collision support (static triangle mesh and dynamic objects), with async collision cooking off the game thread
Full NavMesh support
Variable mesh formats, letting you trade features against memory and performance per-stream
Up to 8 UV channels, high-precision UVs and normals
LOD support up to the engine max of 8 levels, with full dithering
StaticMesh conversion in game and editor
ProceduralMeshComponent migration helpers to port existing PMC code with minimal changes
Blueprint mesh builder, Blueprint-callable shape tools, and a full set of Blueprint example assets
Mesh serialization

Free and open source (source on GitHub). Supports Unreal Engine 5.5-5.8 on all platforms.

Want more? Realtime Mesh Component Pro adds:

Runtime Nanite: build real Nanite meshes from procedural data, with cluster groups, a full LOD DAG, and per-page streaming. No cooked bake, no custom engine.
Lumen GI for dynamic meshes: runtime signed distance field and Lumen card generation, GPU-accelerated, so procedural geometry lights correctly.
Hardware ray tracing support for runtime-generated geometry.
UDynamicMesh rendering through RMC's render path, with bidirectional conversion.
Spatial streaming for loading and unloading mesh cells around the player.
Compute-shader providers for geometry that lives entirely on the GPU.
Runtime OBJ loading and meshoptimizer-backed mesh optimization tooling.

Same API, so a project moves from Core to Pro without changing existing code.
