View Full Version : help with glass refraction
Titan 08-21-2002, 03:09 AM I'm trying to create a glass texture that refracts or distorts, and magnifies as it passes in front of another object...
anybody have any good shaders or tutorials or can tell me how to achieve this effect procedurally?
this texture will be used on a creature, if that helps...not an object, and it also has a noise bump displacement..
any help is appreciated.,..

new material
click the button at the right that says "Standard" to bring up the material map browser
choose "raytrace" from this list
index of refr: 1.5
transparency: white
now lets choose a material to refract
new material
click get material (icon in the same row at the goto parent icon but al the way to the left. looks like an arrow pointing down onto a circle)
look framiler??? now click the "mtl library" from the left most list under "browse from:"
my list defaulted to a text list but I like the small icons more. click the button at the top that loks like three circles, blue green and red, with small lines going to the right.
at the bottom choose "wood_cedfence"
close material/map browser
close or minamize material editor
now if you want this to be glass choose your raytraced material and turn your specular level to 200 and glossiness to 65
create a shpere in your top viewport about 30 units in radius
in the rolllout on the right set hemisphear to .5
check the squish box
make sure your sphere has the default 32 segments
create a plane about 200 units square in your top view port aproximatly centerd under your sphear
now apply your clear glass material to the hemisphere and your wood to the plane
in the material editor click on the preview window fo your clear glass, which should look only like 2 small white highlits
now click and drag this material to your sphear or click "assign material to selection"
do that same but with your wood texture and your plane object.
render!
hope thats helps
