Hey Helge, nice tool! Thanks!
But I seem to be getting an error. I downloaded the zip and installed the addon
. Created a sphere and hit addNormals button on the userNormalsTools toolbar.
I get the following error(s):
'ERROR : 2000 - Argument 0 (Target) is invalid
'ERROR : 2001-GetValue - Argument 0 is invalid
'ERROR : 2000 - Argument 0 (Target) is invalid

Am I missing something?

Every time someone shakes Helge a tool drops out. ;-)
I've not looked at the tool, Helge, but a couple of thoughts all the same.
Years ago, when I had the tools to manipulate normals on the models I was
building, the most useful stuff was not so much the ability to manipulate
normals directly so much as those that provided tweaks that calculate normals
in a more useful way. One example of where you might need something like this
lies in the old cube/bevel thing. Currently applying bevels on cubes either
completely screws the shading or forces you to jump through hoops to get decent
shading along those bevels. Normal calculation is done by averaging plane
equation normals on a point's neighbouring faces and one way to give the
appearance of rounded bevels along edges is to flag the bevel faces as not
contributing to the normal calculation. This is something I've been meaning to
do for months but if you've already got the guts in place, it may be something
you can add quite quickly.
just a thought,

I see.
Yeah, you can deform them, or even shape animate them.
works pretty well.

Hi Helge,
The fact that UserNormals are not used with subdivs is a limitation, simply
because the UserNormal support in XSI is still in early stages (since v3). The
primary usage for UserNormals was to give some ways to enhance the shading of
low-poly models, and in that perspective, support over subdivision surfaces was
not a priority.
Obviously it would be nice to have UserNormals supported for subdivs, the
same way that it would be nice to have them following animation. These are
things that we wish to add in the future, but I can't say when, as will depend
on the priority relatively to all areas of XSI...
Using your trick of having a hidden mesh controlling the tip of the
UserNormals, it would be interesting to see how it behaves if you apply the
same deforms / enveloping to the displayed and the hidden mesh; the normals may
be behave relatively well.
Thanks for your tool,
Jerome Couture-Gagnon.

Conversation: user normals
Subject: user normals
HI list,
I just finished an interactive user normal addon.
Can anyone point me in a direction concerning that:
When using user normals, and turning on geometry approximation,
the user normals simply disappear and are not used for shading anymore.
Is that the way it is supposed to be? I thought the geoapprox mesh's
normals are simply interpolated user normals (as long as there are user
normals, so to speak)
