#Transparency Falloff
6 messages in this thread
I have been using transparency falloff on a testtube I have created but
have the following problem. Transparency FO seems to be measured from the
overall dimensions of the object so on my tall testtube I got the desired
effect left-to-right but have a "whole" in the middle from the
top-to-bottom aspect of the fall off. I _want_ only horizontal FO. I can
think of several somewhat involved schemes to apply materials with
successively more transparency to selection sets of faces running
certically (oops, vertically) along the object. Can anyone think of a
better (read easier and less time consuming) way?

PS. Anyone else feel like everyone's gone to an office party while you're
still at work?…
Chris: I don't have an answer for you (yet…) but I have a similar problem
trying to do a model with two colored solutions diffusing into each other.
I got a suggestion to use an animated texture map but I haven't worked out
a map that I like yet.

P.S. Yup! I have a note on my calendar this week "SIGGRAPH in Chicago" and
under it "Chris in Cleveland"…
I got the same suggestion from Gary (as you probably read) re: animated
mapping. I created the appropriate opacity maps today and am going to
render them tonight. I can see now that animated mapping solves a _lot_ of
those problems about how tomake something look real without having to
actually model the known universe.
Let me know how your blended texture maps turn out. That will definitely be
a technique I'll need.

Chris: I'll keep working on the animated texture maps and let you know how
they work out. An opacity map would be fine for one material diffusing into
another, but I need two materials diffusing into a third.

Good luck!
Chris
Thanks: I'll play with it this weekend.
