Ok, Ok... Now that I have little hair left (didn't start with too awful
much) can someone explain the grid texture use in gradient applications?
For example a cube that when having a large grid texture applied as a
transparency map starts fully visible at the top slowly fades away at the
bottom.
John Gross, in the January issue of LWPro there was an article on the
Fireballs that got me playing with the grid texture. It used it as a
luminosity and Diffuse map. But mine didn't quite fade out enough in the
back.
I've read it save memory over loading a greyscale gradient and applying
it, but can't seem to understand the concept of how the grid works.
I assume you size the grid so that one line covers the entire object,
then set a falloff? Can't get it to work right!
Could anyone explain the settings for say the above cube example?
Nothing fancy, just settings on a 1 meter square cube that is 0%
transparent at top and 100% at bottom.
Thank you all in advance for your assistance.
