    I'm using the new RenderMesh component, and it seems that the automatic frustum culling it does doesn't take shadows into account. For example, if I have a cube casting a shadow on a plane and I move the cube slightly out of the camera view, it's shadow disappears as well.

    Looking through the change log, back in 0.0.7 I saw this:

    "New system for frustum culling meshes processed by MeshInstanceRendererSystem. Add a MeshCullingComponent to the entity and it will only be rendered when it is in view. The culling system does not take shadows into account."

    Is this still the case with the Hybrid Render system? If so is there anyway to turn off or otherwise modify frustum culling? Any other suggestions?

    You can set WorldRenderBounds IComponentData with larger AABB to cover space with shadows.

    The renderer we used on megacity solves this problem. It requires 19.1 changes, but we are working towards exactly this.

    Hello everyone,
    I'm doing my own hybred renderer and I'm facing the same problem.
    Is there a way to add shadows to the WorldRenderBounds component ?
