This should be in p.n-u, but here we go,
Could someone explain to me the difference between a procedural texture
and a texture, are they the same?? Boy, I am so confused lately ;-)
Thanks a lot.

"Textures" is a cover-all.
"Procedural textures" are those textures created without using image-maps,
etc.
So a procedural texture is a texture, but a texture isn't necesserily a
procedural texture.
BTW you've posted two copies of this message.

You are going to get a lot of people disagreeing with you on this one.
An image map is a pre-made texture. A proceedural texture is one that
is made from various elements such as pigments, color_maps, and
pigment_maps etc...

That's essentially the difference.
In fact 'procedural' means according to an algorithmic definition in
contrast to a texture purely based on data like an image map.
You can of course combine both techniques by adding warps to a image map
for example.
Also function pigments using the 'i_dat3d' library functions in megapov
could be interpreted as somewhere between.

They'll have to find me first... you are right (of course). The point is
that, IMHO, a texture stops being procedural as soon as you use an image
map. Okay, pigment{rgb 1} isn't procedural, but it could become procedural.
As soon as you use an image map, there's no chance of the texture (IMHO)
becoming procedural.
