Hi all,
This is not directly OSG related, but since many here know Creator very
well I presume, I thought I'd ask.
I have a model which the modeler has scaled, and as we can expect it
exhibits the classic symptom that the normals were scaled as well -
lighting is wrong. In Creator I can click the "show normals" button and
I can see that some normals are markedly shorter than others.
I can't seem to find any tool for "normalizing" the normals in Creator
though. There's the "Attruibutes - Calculate Shading" tool that lets me
recalculate the normals, but even this doesn't seem to normalize them.
If I use osgconv to convert the model to .osg, and add a stateset with
GL_NORMALIZE ON on the root node in the file, then the shading is
correct. So I know this is the problem. I'd just like to know what to
tell our modeler so he can fix the model directly instead of using
GL_NORMALIZE or the osgUtil::SmoothingVisitor (I'd like to avoid extra
steps). And it would seem a rather glaring omission if Creator scaled
normals when scaling a model, but didn't give you a tool to renormalize
them afterwards (or even renormalized them automatically - gasp!). Am I
missing something obvious?
Thanks in advance,
J-S
