Ok, I want to be able to do either one of the following:

- Make a wine glass on a table but having the glass look realistic with water.

- Make a simple glass window payne.

Can anyone help? I have Maya 7.5.

make sure your glass has more than one width... i mean make the glass thicker than 1. so you have outer glass and inner glass. then stick on refractions in mental ray. 1.6 i think is the refractive index for glass (you should check) then put the number of refractions up to about 6. that should cover the outer glass (1) the inner glass (2) the surface of the liquid (3) the other surface of the liquid (4) the inner glass again (5) and the outer glass again (6).

i have had a drink tonight but that should sort you out i reckon.

btw, dont forget to put the colour to black and tranparencey up. the reflections down and then fiddle with the spec roll off etc etc.

hope that may have helped.

blinn btw...

actually i'll do a couple of revolves and see if i can make something quickly... 2 secs.

ok so i fell asleep last night (could have been the drink)

this is what i did last night, it took about the same amount of time it took me to eat a kebab.
all i did this morning was add a spot light...

not great i know, but it was quick, so with more time you can get nice looking glass. bear in mind that i've only been using maya for a couple of months but i hope this helps.

Refractive index for normal glass is 1.5. water is ~1.3.
Make sure you've got some reflections too(not too much) since every time light bends it's also reflected to a certain amount.

When in doubt, delete history and freeze transformations.
