Seeking Texturing Advice 2004-07-12 - By James Edward Gray II
Back
My modeling skills have been steadily improving. (The Handbook has really
helped here
and I would recommend it to others.) Now, I find myself reasonably capable of
making
most shapes I desire, and woefully unskilled at texturing them.
I've read tutorials and looked at plenty of shaders. That's helps a touch, but
mostly it just
tells me what settings to duplicate to get that exact effect. It's not helping
me think in
procedural shading techniques.
So, my first and most general question is, any advice on the steps to picking
up shaders?
Now for some more specific questions relating to my current problems:
It's probably just me, but I don't get the Color Gradient setting. Can anyone
explain how
to use this or even where this is handy?
What is the easiest way to actually throw a top to bottom gradient on an object
? I can do it
with Elevation, but then I always seem to struggle a bit with the right height
and blend
settings. Which leads to my next question, really...
Global Space vs Local Space. Okay, I think I get this. Global is using the
scene
coordinates, right? And Local is object specific coordinates? Where's 0, 0, 0
in Local, the
object's center?
Last gradient question. Is it possible to make a procedural shader that has a
gradient
repeat X number of times over a given access? I've had no luck here, though I
can of
course do it with a texture map.
Switching gears a little. What's an easy way to shade some "grooves" into the
bump
channel. I tried using Noise and scaling it along one axis. That's close but
not really it.
I'm looking for the lines like you would see in a rough wood grain, if that
helps.
Thanks for the help. I'm trying, I promise...
