    I know that the cube map is a baked image – is there a way to update it when an object is moved or is there a better way to show reflections of moving objects ?

    I am curious about the question you are asking.

    Let’s take the basic idea of a sphere in a colored box.
    You set up a spherical light probe on the sphere. You are careful not to parent the light probe to the sphere. You animate the sphere going in and out of the box.

    The reflections work and animate with the sphere movement.

    Why do you need/want to update the cube map manually? You can do it with the update lightprobes puzzle….but you would have to do that per frame or per time increment and its not something I would recommend.

    Can you give more info on what you are trying to accomplish?

    is there a way to update it

    https://cdn.soft8soft.com/demo/examples/index.html?q=cube#webgl_materials_cubemap_dynamic
    requires a lot af video memory.

    This example is more video memory friendly:

    Puzzles and JS coding. Fast and expensive.

    If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.
