<pre wrap="">Hi Brecht,
Just tried the recently modified Bump node and notice negative values seem
to be clamped to zero, is this intended?
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.
What are your thoughts on implementing a Invert option on the Bump node?
Some mock-ups
