Can you help me to make glass material in LightWave 7.5(like on photo)?
Thank to all for help.

I suggest you go to this site and have a look at the jack daniels tutorial. it should get you on the right track.

liquid arts (http://www.liquid-arts.de/welcome.htm)

If you dont come right on your own I will post a surface that should more or less suite your needs

Sorry Yon, but that picture show glass..

ACtually that's a Chunk of glass, we have one just like it , but instead of a bike, we have my daughters face..

It's been eteched on the "INSIDE" wiht a laser.. they are pretty cool.

About the above tutorial... Does anyone know if you still have to create Air surfaces for proper glass refraction... I thought you didn't have to do this in newer versions of LW.

Thanks for your time.

still the same thing air- and glasspolysget the best results

yes, you still have to create the air surface.
it's not an issue of lightwave, indeed it allows you to choose the material floats on (like glass on water and so on)
mikrob, i assure you that if you take the time to read the post i linked before you'll find what you're looking for. (yes, there are the object/scene files)

sorry for the delay, have been a bit busy. I cant just post you the surface settings because there is more to glass than just settings. Glass needs to be lighted correctly, and it needs an environment to reflect. The model also needs to be built correctly to get proper refraction.

Attached is a render of a scene you can download here (http://www.multisports.co.za/temp/mikrob.zip) .

It is a lot "warmer" than your photo, but thats because I cant guess what environment your cube was in when it was photographed, and what lighting was present. If you changed the scene to simulate that environment (lights and texture map) it would be closer. The refraction details are correct and present.

when examining scene, notice the following in particular:
quick fresnel plugin
caustics (dont know why they came out so vivid??)
double polygons on cube object

hope this helps.

As dies-irae pointed out... you can find a sorta break down for making a glass cube in Lightwave here. (http://www.cgtalk.com/showthread.php?s=&threadid=6307&perpage=15&pagenumber=1) .

Dies-irae makes a nice breakdown in that thread... the idea was modeling an air bubble in a glass cube..... the end result looks like the pic below... and an animation of it can be seen HERE (http://www.opnotic.com/wip/bluecaustic.avi)
