In my age I have stainless glass and other glasswork.
The glasswork, if it is rendered have a nice look through, but when I see it in Uru it is mat.
My stainless glass is nice and I have made in photoshop a shining look in it. But the stainless glass must also look throught. So can someone tell me a good setting for this two items. ;)

For transparent textures you have to save the pictures as png in your external program.

In blender you have to activate the button "alpha" (F6/Preview and "use alpha" (F6/Map Image)
Perhaps you have to set the passindex to 1(F7/object and Links).

I don't kow more about this. Perhaps it will help you or other peolple here could say more about it.

To make a material transparent, just set the "Col" slider in the "Map to" tab to a value less than 1, which is totally opaque. You may also need to tick the Object->Draw->Transp button, for the window pane object, to make sure it "goes into a blend span" and give it a higher Object->ObejctAndLinks->PassIndex value, to put it later in the order stuff is drawn.

I suspect your windows may be leaded, though, in which case you will have to draw an Alpha channel, as described by Perlenstern, so that only the glass turns out transparent and not the lead mesh.

To make the glass shiny, give it some specularity (set the "Spe" colour to a non black colour - this colour will be added as extra light, on top of the diffuse shading).

For any lead bits and if the glass has an irregular surface, a normal map could be handy, making little pits and bumps catch the light, but we don't know how to use those in Plasma yet. :7


EDIT: "Object buttons" - not "Edit buttons"... :7
