Objects not redering in build

Objects are rendering in editor but not in build.

I saw some examples using TransformMatrix, but the name is not recognized. I think it should be in Unity.Transforms.

Maybe it's another component now? Am I missing something?

Code (CSharp):

1.  
2. particleArchetype = entityManager.CreateArchetype(
3.   ComponentType.Create<Position>(),
4.   ComponentType.Create<Speed>(),
5.   ComponentType.Create<MeshInstanceRenderer>());
6.  
7. Entity particle = entityManager.CreateEntity(particleArchetype);
8.  
9. entityManager.SetComponentData(particle, new Position { Value = position});
10. entityManager.SetComponentData(particle, new Speed { Value = velocity });
11. entityManager.SetSharedComponentData(particle, new MeshInstanceRenderer()
12. {
13.   mesh = particleMesh,
14.   material = particleMaterial
15. });

 

TransformMatrix is now LocalToWorld, but this is not the problem.

EndFrameTransformSystem is not being called. Should it run on build?
