Re: worldaxis RGB depthfade/distance shader?

["Tim Leydecker" <BauerOink(at)gmx.de>]

O.k.,

I got the shader working using three Texturespace Generators
but fail when I try to assign it to other objects, do I really need
to (re)link to the correct TextureSupports for every object or
do I miss something obvious?

I would have thought the Texturesupports transfer automatically
with a shader (if it´s a projection at least).

Any help appreciated, I´m stuck quite a frustrated. Scene, 200kB:
(mind wordwrap, may require XSI 5.01 adv but shouldn´t)

Image showing result (as desired but what I can´t transfer to other 
objects):xyzaxis_gradient.jpg

http://www.hafenlola.com/downloads/xyzaxis_gradient.jpg
(mind underscore, 58kB)

What I´m trying to achieve, in a nutshell, have three projections, scale 
their
support to my liking and have them align to the worldaxis or parented to a
light to have a way of finetuning volumetric effects, falloff and intensity 
by
the gradients *projected* into the three dimensions. For example.

Cheers

tim
