Frustum culling issues

Im using 2019.1 beta with up to date packages. I create meshes on the fly, adjusting RenderMesh and Translation components as required:

Code (CSharp):

1. var rm = EntityManager.GetSharedComponentData<RenderMesh>(e);
2. rm.material.mainTexture = texture;
3. rm.mesh.SetVertices(verts);
4. rm.mesh.normals = normals;
5. rm.mesh.RecalculateBounds();
6. var pos = EntityManager.GetComponentData<Translation>(e);
7. pos.Value = new float3(x, y, z);
8. EntityManager.SetComponentData(e, pos);
9. EntityManager.SetSharedComponentData(e, rm);
10.  

I am seeing too aggressive frustum culling though, which I currently solve by setting a huge extent (note the * 20):

Code (CSharp):

1. var rb = EntityManager.GetComponentData<RenderBounds>(e);
2. rb.Value.Center = new float3(x, y, z);
3. rb.Value.Extents = rm.mesh.bounds.extents * 20;
4. EntityManager.SetComponentData(e, rb);

This is obviously not ideal, does anyone know how to solve this properly? I create my entities like so:

Code (CSharp):

1. EntityManager.CreateEntity(typeof(RenderMesh), typeof(Translation), typeof(LocalToWorld), typeof(RenderBounds), typeof(WorldRenderBounds)

 

Why is "too aggressive"? It works as expected. You set you mesh bounding box sizes and if it's not inside frustum pyramid - it's culled.

 

By too aggressive I mean it culls still visible meshes. Does the above code looks like it should work?

 

Mesh visibility related on bounding box position and size. Are you shure your bounds correct? Show them in scene view by debug draw line for example.

 

This did the trick, think I messed up setting Centre:

Code (CSharp):

1. var rb = EntityManager.GetComponentData<RenderBounds>(e);
2. rb.Value = rm.mesh.bounds.ToAABB();
3. EntityManager.SetComponentData(e, rb);

It's a bit unfortunate we have to add asmdef references for things like ToAABB to show up, in this case Mathematics.Extensions.Hybrid is required.
