glas

hi all!

when i render glas with a thickness like a glas plate for a table, i can not achieve the look i want.

f.e. the egdes of the glas and the faces on the small side of the glas are supposed to be much darker than the upper and lower faces..

a glas plate 1x1X0.02 m the 0.02m part should be totaly non transparent.

i tried some settings with vray, but can not get it to work..

Usualy the real glass with 2cm thickess is frosted in those faces, did you already try?

I think it should do the trick

Use Psy’s FTP instead:

here’s the ftp info and plz make a folder of your username.

Domain: ftp.3dmaxedout.com
Username: vray@3dmaxedout.com
Pasword: govray

look at http://vray.3dmaxedout.com/ for the file after its uploaded.

tried..

but it does not accept the pasword..

Try again with a different FTP client, it works from here..

may be some problems with our firwall. admin is at home of course..

anyway.. is it so hard to figure out the problem with the glas without images?

s.wolf

The fact that glass is darker in those thin sides IS because of refraction. All glass is colored, usually greenish a very little bit. This is where the fog color gets in. The thicker the object, the darker it’s color. So when you have a very thin piece of glass, you can look through it easily (it looks as if it’s not colored). But when you look at it straight on the edges, it’s actually very thick (from that point of view) so it get’s dark.

Now if you look at it from a normal angle, the ray that goes into the thin side is refracted inside the glass, and comes out on the other side, causing a very dark color on your edge.

or something like that :slight_smile:

flipside

make sure the username is exact.

vray@3dmaxedout.com

looks like an email addy but its the username.

flipside,

That’s the best explanation of glass refraction I’ve ever heard. Nice and simple. Good stuff!!
