Has anyone of you guys logged a feature request to have
the *.spdl and the templates updated?

On Zap´s page, there´s also a hint regarding the use of
the arch&design material or mia_material, whatever:
http://mentalraytips.blogspot.com/2007/01/tricks-and-tips-for-miamaterial.html

It´d be great not to have to hack the *.spdl as this
again complicates working remotely or collaboratively.
No big deal, every custom shader has the same effect, but still...

Cheers

tim
