    Hi all!
    I would like to set an object scale in my scene (a 3D gizmo) relative to the 3D viewport size, so that the object size remains constant whatever the camera zoom level is.
    Anyone had the same need and could point me to the right direction to achieve that??
    Any help will be greatly appreciated!
    Cheers

    @kdv77kdv I think I might already have the exact function for that, right?
    function setObjectScale(mesh, factor) {
    right?
    Can I call this function from any other location in my puzzles using the javascript puzzle?

    It’s a local function not visible in globals. But you may copy its code to use in some other function.

    Puzzles and JS. 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 meaning at all.

    Ok… and could you give me a hint or two about what I need to change or add to adapt this function to my needs??
    Thanks!

    Hint: read the code carefully.

    Good hints, as usual… ;)
    I quickly identified that this “function within a function” – local function – was not directly accessible, and as suggested copied it in a custom procedure in my puzzles.
    Just had to identify that I needed to properly set the “mesh” using the getObjectByName function and that’s it! :yahoo:
    Thanks again!
