Transparent floor

[stelvio.rosset]

Very good day, anybody can suggest how to create a glass (transparent) floor, or better a piece of that? Thanks a lot for the help. Stelvio

Here's my suggestion:
- Create a new home
- Choose Plan > Add level menu item
- Select room creation tool and draw the shape you want
- Choose 3D view > Modify 3D view menu item and select the transparency level you want with Walls transparency slider
- Choose 3D view > Export to OBJ format and confirm the option Export selection when prompted
- Import in your main home the exported OBJ file with Furniture > Import furniture menu item

Hi, thanks for the hint, yes this solution works; there is any additional possibility just to assign to the floor the glass material similarly to the windows object? Thanks

If there was a simpler solution, I would have cited it first [;)]

Thanks for your help, I will proceed as you suggested. Stelvio

Thanks for this great trick!!

I now use it for tinted windows!!

black wall ->> opacity adjustment ->> export to obj

Excelent! Worked perfectly and saved me an hours trying to get it to work in blender.

Personally I find it easier to edit the exported object and add a d value (transparency) to the material I want to be transparent. In most cases you only want one part to have transparency and with the manual edit that's just as easy.

This is explained here and here .

Maybe even simpler solution: Create a transparent png and use it as an imported texture in Modify 3D View / Ground.

Simpler? For me setting the d parameter is just as simple.
With a texture image you are stuck with that image. Using the d property in the mtl file leaves you the option to change colors for semi-transparent objects like tinted windows.
Besides that, a texture increases the imported object size with the size of the texture. It also increases the rendering time for a photo.

You can import the glass object and resize it to any format you need.

A nice trick: import the glass as a staircase and you can can insert a partial glass floor. Rotate the pane horizontal and make the depth the same as the floor thickness. Elevate the glass in the room below to the wall height. Done, a nice glass 'hole' in the floor.
