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>

Thank you for your time,<br>
