How do i make glass transparent?
I followed a tutorial to make it since i'm really new to maya, this is my first project.
I followed all the instructions but my glass turns out like a mirror instead.
I don't know what setting is wrong. And i'm using maya 2013 since my laptop doesn't support newer version of it.

The result i made:

The mia material x settings i have:

The result wanted:

Anyway, i know the lighting and caustics is still a bit weird.
If you can help me with that too that would be very appreciated! user added image

that lesson doesn't go over the refractions settings, so I'm guessing the people that managed it already had theirs set higher in their render settings,

id recommend getting a demo digital tutors account to do some lessons like this to understand it
https://www.digitaltutors.com/lesson/...errors-in-Maya

or the simplymaya rendering glass tutorial

The short sweet answer is that face normals determine which is the back and which is the front side of any given polygon. Normals can affect things like how reflections and refractions are calculated which I think is the problem in your case.

You can toggle their display through the Display>Polygons>Face Normals. Or a quick and dirty way of checking by a glance is to turn off "Two sided lighting" under your panel "Lighting" menu, there will be a color difference between the front and back sides. You can change the normal direction of the offending objects or components by selecting them and going to Normals>Reverse.

More on normals>>

Does not look like Gen is about at the moment so I will answer your question, in the polygon menu go along to "normal" then down to "reverse", if that does not work unlock the normal first then "reverse"..............dave
