Blender Addon

Addon, that allows you to export your scene into the Roomle Configurator Script format, accompanied by .
Currently the addon is only provided as an installable zip file by Roomle directly for partners, clients and customers.
You can download a ready-to-install package from the folder.
Advanced users can check out to build it themselves.
TODO: Apply Rotation and Scale on all elements (hierarchy of emties and objects)
Open Blender 3.5 (or later)
Navigate the main menu to "Edit" > "Preferences"
On the left side, click the "Add-ons" tab
Click the "Install…" button at the top right
Navigate to the downloaded roomle_blender_addon.zip file and install it
Now the addon is installed and needs to be activated. It is called "Import-Export: Roomle Configurator Script" (Blender usually pre-filters the addon list after installing, so it's at right the top)
Make sure the addon is activated by checking the checkbox left of its name.
If you click "Save User Settings" on the lower left, you make sure the addon is activated the next time you start Blender.
The export now can be found in the main menu at "File" > "Export" > "Roomle Script (txt)". For quicker access, it can also be found in the search menu.
On the lower left side of the file dialog, you can find some parameters for the export.
Materials and external meshes are referenced by an identifier in Roomle Script, which consists of a Catalog ID and an mesh/material ID, separated by a colon (:). The catalog ID is provided by Roomle to you. If you happen to know it and provide it in this input field, all references will already have the correct catalog ID in the output script.
By default, all objects containing meshes (so no cameras, lights, aramtures, etc.) in the scene are exported. If this option is enabled, only the currently selected objects will be exported.
By default the mesh normals are not export, but (smooth) normals are calculated at run-time. To gain finer control of the normals, check this option.
When this option is checked, rotations on objects will be applied into the geometry. This is the preferred way, since this calculation would otherwise be done at run-time (slower).
Only un-check this option if you plan to rotate the meshes in your script later on anyways.
WARNING! Do not play with these settings if you are not 100% sure how they work.
Checking the Advanced Settings will unveil some more options.
In Roomle script there are two ways to add custom geometry.
Internal meshes: AddMesh command with all mesh data as in-line parameters.
External meshes: AddExternalMesh command, which loads an external, compressed mesh file.
In general external meshes are the preferred way, since they require a fraction of the space of their AddMesh counter-parts and load much faster and efficiently.
However, they require an additional network request at run-time. So for very simple objects (meshes with a with low triangles count) it makes more sense to include them in the script. The addon will automatically decide whether to make the mesh internal or external.
External meshes are expored in a subfolder which has the same name as the script file (.txt) itself. These are triangulated meshes, by default in Wavefront OBJ format. These files have to be uploaded to Roomle before they can be used.
Upon upload, external mesh files are further compressed to become even smaller. This compression is lossy and can yield in artifacts. Feel free to report abnormities.
Try to apply rotation and scale on all objects, since these operations are otherwise calculated at run-time.
The addon has (limited) support of re-using mesh data. So try to re-use mesh data blocks wherever you can and do not give them individual scale and rotation values.
The addon also comes with a handy optimize operator, which does some of the best practice optimizations automatically.
You can find it only in the search menu, labeled as Optimize Roomle static. This operator will:
Remove loose vertices (not attached to any face).
Center your objects at the scene origin, so that the bounding box is in the middle.
Reset all transforms and apply the rotation, scale and location into the mesh data.
Advanced developers can build the addon themselves. Note that we cannot provide support for custom builds.
There's a script called build.command, that packages the addon into a zip file. This works on macOS and should also work on Linux.
Double click at build.command
The file roomle_blender_addon.zip is created.
Note: Shading something flat (via Shade Flat operator) in the Blender viewport has no effect yet on the output script. Please break edge connections whenever you want a hard shaded edge. The easiest way to do this is the modifier.
By default smaller meshes are exported as in-line AddMesh commands while bigger meshes are exported in separte files (see for detailed information). By changing this option to "Force intern" or "Force extern" you can override this decision. Warning: intern meshes create huge script files and become very slow to load at run-time.
Please report any issues or bugs you experience in the .
