Is there an alternative? the procedural mesh component is incredibly slow.

You would need to convert procedural mesh to dynamic mesh

From ProceduralMesh to DynamicMesh

I have a ProceduralMeshComponent which receives a simple array of vertices, indices, normals, uvs, etc. I need to update the vertex colors dynamically and my understanding is that a DynamicMesh is preffered (more efficient). So I’m converting to creating a FDynamicMesh3 instead to insert into a DynamicMeshComponent. Instead of a single call with arrays of all the data, the only way to construct such a FDynamicMesh3 seems to be to add the vertices one by one, and then set the triangles one by on…

Enable the plugin Geometry Scripting and try “Copy Mesh to Static Mesh” which converts dynamic mesh to static mesh.
Then you can copy the dynamic mesh to a new static mesh which should be more performant.
