    Hi Brecht,<br>
    <br>
    Just tried the recently modified Bump node and notice negative
    values seem to be clamped to zero, is this intended?<br>
    <br>
    For a less cluttered noodle space, rather than adding an Invert
    node, I occasionally use negative values for inverted bumps.
    Although due to dyslexia that method has its drawbacks, negative
    values are not always obvious at first glance.<br>
    <br>
    What are your thoughts on implementing a Invert option on the Bump
    node?<br>
    <br>
    <b>Some mock-ups</b><br>
