[UDK] Glass Door Help!

HornyRhino

Hey guys... i have had an idea for a simple scene i wanted to do but i have come to a Halt at processing and knowing what i need to start this scene... i need to put in a glass door but it has a Metal frame Under and up top of the glass frame... what i would like to know is do i have to make UV coordinates of the glass individually from the metal frames or can i keep it all in 1 UV layout? and if its all in one layout how could i get the glass to be transparent and not effect the Metal frames?

Thanks. :poly136:

You can have the materials all on one texture sheet and just use a grayscale mask to determine which parts of the model will be translucent.

To make it easy Id make two materials. This also allows you to associate two different physics materials easily later. You can separate physics materials with a mask or mask UVs but that's slightly more annoying.

Not sure how optimized you need things to be. If it just has to look good Id prolly just make two materias and be done with it.

two material ID's are probably the way to go here. I'd be a waste of texture memory and performance to mask the frame areas.

also with 2 id's you can make a nicer glass material and reuse it on other things that need glass.

Ok... thanks guys... i will give this a try... i am still learning UDK material nodes, and they dont seem that hard... so hope i can make my way through it.
