    At dots netocode, I believe when u try to change PhysicsCollider data at runtime like changing size it will not sync data to both client and server since it's using blob asset. Does it means I need to create custom component to handle this? Or is there any plan to make blob asset possible to sync data to both client and server in future?

    I'd recommend doing something like this:
    • Create a "ColliderSize" Component, with a "float Size" ghost field
    • Have a system that runs on both client and server, which sets the size of the collider based on that "Size" value
    In other words; control the size of the collider based on some ghost field in a ghost component, and avoid changing the size every frame by only changing it if it's different from the current size (you may want to store the last applied size in a non-ghosted field for quicker comparison)
