Question Run Mesh.SetVertices in parallel

Hello,

I have a scene where there are multiple meshes, and there is a job system to update the vertices of these meshes using the Entities.ForEach and ScheduleParallel() manner, which is working fine.

I also have another job to assign the updated vertices back to the meshes and recalc the normal as the following, but it only allows .WithoutBurst().Run(). Is there a way to run the mesh update job in a parallel way? thanks.

Code (CSharp):

1. public class UpdateMeshVertex_JobSystem : SystemBase
2. {
3.     protected override void OnUpdate()
4.     {
5.  
6.         Entities.ForEach(
7.         (
8.          in DynamicBuffer<Vertex_Element> vertex_buffer,
9.          in RenderMesh RM
10.          ) =>
11.         {
12.  
13.             RM.mesh.SetVertices(vertex_buffer.ToNativeArray(Allocator.Temp).Reinterpret<Vector3>());
14.             RM.mesh.RecalculateNormals();
15.  
16.         })
17.         .WithoutBurst().Run();
18.       //.ScheduleParallel();
19.       //error DC0019: Entities.ForEach uses ISharedComponentType RenderMesh. This is only supported when using .WithoutBurst() and  .Run()
20.     }
21. }

 

See Mesh.MeshData for writing to vertex buffers from C# jobs:
