glase pane in door

[JosSc]

Hi, I like to have a transparent glass pane in a green door. I found a post from rcheng in 2014 on this subject and Hans Dirkse gave the solution by means of a link. But the link is broken.
I tried to reply on the original post, but it does'nt work either.
Who can help?

When you modify furniture you can see the material names that are used. The selected material blinks in the modify materials dialog. Note the material name of the glass and cancel the dialog.

Export the door which generates an .obj and .mtl file. Open the mtl file with a plain text editor and find the material name used for the glass. That is a block of lines that start with the line "newmtl <materialname>".
Add a line d 0.3 at the end of that material block.
Save the mtl file and import the door by dragging the obj file in your 2D design window. Your glass should now be transparent. You can change the value on the d-line between 0.00 (invisible) and 1.00 (opaque).

If you already have an .obj and .mtl file and know what the material name for the glass is you can just edit the mtl to add the d line file before import.

Thank you. I can use your method whenever I have a door with a pane in it: then I can select the material and edit the file to make it transparent.
But unfortunately I don’t know how to get a pane in a door. I think I first have to put an invisible box in the door; then add a fixed window; and then make the window transparent with your method. Unfortunately the only invisible box I could find doesn’t work on a door, only on walls.
So I like to ask for your help again, starting with a standard door and made it green. Which steps need to be taken to get 9 small glass panes (in Dutch: negen ruitjes) in the upper half of the door.
Hope you can help me again.

That is very difficult with an existing door, at least in Sweet Home 3D. If you are lucky you can make the upper panel like glass (d 0.3 in the .mtl file) and add thin boxes to divide the glass into 9 squares.

Without a separate upper pane you have to either create a new door from scratch or remove more of the door to get the upper hole and refill the now missing parts with boxes.

Check out the DodecagonDoors library on my site. It has a few doors with upper and lower glass panes. You can fill in the lower pane with a box and add thin boxes to divide the upper pane into 9 squares.

A door is very difficult for someone who is just starting with Sweet Home 3D. If you can;t get it right, zip your door obj and mtl file and upload it to a file host like mediafire. Post the download link here. Then I will see if I can fix that door for you.

Dat is erg lastig met een bestaande deur, in ieder geval in Sweet Home 3D. Als je geluk hebt kun je het bovenste paneel als glas instellen (d 0,3 in het .mtl-bestand) en dunne kubussen toevoegen om het glas in 9 vierkanten te verdelen.

Zonder een apart bovenpaneel moet je ofwel een nieuwe deur helemaal opnieuw maken, ofwel meer van de deur verwijderen om het bovenste gat te krijgen. Dan de nu ontbrekende delen opvullen met kubussen.

Bekijk de DodecagonDoors bibliotheek op mijn site. Daarin staan een paar deuren met boven en onder glas. Je kunt het onderste glass opvullen met een dunne kubus en dunne kubussen toevoegen om het bovenste paneel in 9 vierkanten te verdelen.

Een deur is erg moeilijk voor iemand die net begint met Sweet Home 3D. Als het je niet lukt, zip dan het .obj en .mtl bestand en upload het naar een filehost zoals mediafire. Post de download link hier. Dan kan ik misschien die deur voor je fixen.
