Look in the galley, once you see what you want leave a comment asking for the settings.

You can also start with the default glass setting for the UI, and tweak from there to your desired settings.

Yo usaria unos de los materiales vidrio que vienen con nxt y luego intentar cambiando unos parametros. Basicamente tienes que haber un fondo hdri, que no necesariamente tiene que ser igual al cielo. tambien, no olvides que el reflejo depende del angulo de mirada. Pero si el vidrio es muy reflejante, pierde de transparencia, asi que hay que intentar bastante.

Trying to reflect the background in the windows is somewhat harder than trying to reflect actual objects in the scene. In either case, always start with an accurate glass material. For example, start with the template glass and change the IOR to 1.55.
To reflect the background, use a good quality, spherical HDRI to both light the scene and provide the background (perhaps combined with appropriate direct sunlight.) Put the sky on its own lighting channel so you can play with its brightness levels in case the HDRI is not properly calibrated to the sky. Use the built in mouse-over light meter to verify that your sky values are reasonable.
Use the exterior lighting preset but change the lighting to HDRi

Hi Roy, can you explain where is the build in mouse over light meter an how it works. Also another question, which are reasonable values for the hdri? thanks in advance

Sorry that should be "built-in" (I'll edit the original post.) It's the Value fields in the status bar as you mouse-over a pixel. It expresses the internal value of the pixel in units of candelas/m^2.
Reasonable values for sky hdri have been discussed before. Some guidelines can be found here.

Me parece bien. El material vidrio es totalmente transparente? Porque parece apenas blanquito.

"The wooden texture of the TV-Console looks quite decent.
The Wallpaper on the left has an interesting structure, maybe it would look even better, if you make the texture seamless + applying a little bit of depth, e. g. with highpass - filter in PS?"

I searched the former forum posts and found another option to solve this problem which is another plugin to autocad-----AUTOMAPKI. You can give it a try."

3ds +obj import works for older files-'xfrog-plants', for instance... .Comments + Critics appreciated!Hopefully accurender still survives!
"Found 'Textured Mesh Support' only works with obj and 3ds Files which do not contain PBR Maps.
To 'obj' converted newer 3ds do not render in nXt :-("
