Modlumi - Easy 3D modelling

[ntxdave]

@pixelcruncher I think these issues are pointing to a need for a user manual or someplace where users/potential users can learn how to use the basics of the software.

@ntxdave
All of your "silly" questions are generally answered on the left Bottom line!
For your number sides'Polygon for example! ;
Just Press + or -

And in general, MOdLumi is quasi the same than the old SU functions!

[pilou]

@pixelcruncher
Yes you right, i was deceived by the CTRL as Copy for the Move, Rotate!
ALT was the key!
But request is for a "move copy" with Scale !
Same for " copy rotation + Scale"
So like this!
(not ModLumi here of course!

Hey folks, another release is out. Here are the release notes (and also the ones I forgot to post earlier.

Modlumi 0.4 – 0.8

Version 0.8 (2026-10-07)

New features

• Start a new, empty model with File → New (Ctrl+N, or Cmd+N on macOS). Previously the only way to start over was to restart the app. If the current model has unsaved changes, you can save or discard them first.
• Paint with image materials. In the Materials panel, choose New image material and pick a PNG, JPEG or BMP file. Set the size of one repeat in your model's units, keep the image's proportions, and optionally tint it. Image materials show thumbnails; click one, or right-click any material, to resize, replace or remove its image. Images are saved in the project file.

Improvements

• Imported SKP models keep their textures. Textured faces previously showed only the material's color.
• Editing models with many nested groups and components is faster. After an edit, Modlumi now updates only the edited part and the objects that contain it, instead of every copy in the model.

Version 0.7 (2026-10-07)

Fixes

• Large arrays of copies no longer look partly transparent. As an array grew away from the origin, edges behind faces could show through. Faces now hide them at any model size. (Original forum report)

Version 0.6 (2026-10-06)

New features

• Round and cut edges with the new Fillet, Chamfer and Bevel tools. Select edges or a face, or click an edge, then drag or type a size. Fillet accepts a segment count, such as 8s, and Bevel accepts a distance with an angle or a second distance. Scripts can use entities.fillet, entities.chamfer and entities.bevel.

Fixes

• Scripts that run out of memory now say so instead of reporting "null".

Version 0.5 (2026-10-06)

Maintenance release with no user-facing changes.

Version 0.4 (2026-10-06)

New features

• Select everything with Edit → Select All (Ctrl+A, or Cmd+A on macOS). Selects every visible item in the group or component you're editing.
• Select related geometry from the new Select submenu. In the Edit menu and the right-click menu, choose All Connected, Connected Edges, Connected Faces, Bounding Edges or Same Material.

Improvements

• Drawing and extruding stay fast in larger models. These operations now work on the nearby geometry instead of searching the whole model, so extrusion previews stay responsive next to thousands of unrelated faces.
• Scripting is now available only in the desktop app. The browser app no longer has Run Script, the Script Console or the Script Editor.

@pilou Cool feature, I will have a look at this.

[pilou]

@ntxdave
Is that more clear ?
Here Arc Circle is a group! Like this you can select it first on the Ouliner!
Draw directely the Offset on the polygon and make the Sweep will not work :the first face will be bad drawn!

The bad way... (for the moment! i suppose a little bug again

[pilou]

[pilou]

Request : a tool selection
If we want select only one face / 2 ... (Loop, ring selection...

[pilou]

[Krass]

Hello Thomas,
the bevel is great !
But I still can't do multiple copies that make new faces

[Krass]

offset tool issue

[pilou]

@krass
For help, you can post a fil .modl ! (Save as)
I believe that is not yet Multiple selections!
(you can select some faces but some functions will not work on them)

For your lat problem above you can try that (i have tested
Select that you want Offset
Inverse selection
Group (and hide if necessary)
Offset on your remake selection...

[Krass]

Pixelcruncher,
will you build a Rayscaper version for Modlumi?

[pilou]

I believe a bug! Of course the same in 3D!
Maybe not a refresh ?

[pilou]

Cool fillets are positive or negative following edges/faces! Excellent!

[pilou]

You must make compoents, and component of components!
If not the direct Copy Move * will freeze or take minutes!
With components it's instant!

[pixelcruncher]

@Krass Yes! But integrated directly into the software, not as a plugin. It's easier to have it directly in modlumi.

[Rich O Brien]

There's a part of me that's wants to know what @pilou types for his prompts.

But there's another part of me that says don't stare into the abyss

[pixelcruncher]

Thanks @pilou and @Krass for the reports and examples! Four fixes went into the code today:

Copies now create separate faces
Copying rectangular outlines onto an existing face now splits the surface into independently selectable regions.

Offset works on the copied regions
The related “affected coplanar faces have overlapping interiors” error is fixed. Copied geometry now integrates with the surrounding surface, allowing Offset to work normally.

Sweeping an offset ring leaves both ends open
Offsetting the flat polygon first and sweeping the outer ring now produces the expected hollow shape, without blocking the starting opening.

Move copy arrays are much faster
An 11 × 11 array of loose cylinders took 34.8 seconds before and 0.61 seconds after in our desktop test. Components remain useful, but loose geometry should no longer suffer that particular slowdown. Browser timings haven’t been measured yet.

Keep the bugs coming; I'll keep squashing!

Cheers!
Thomas

The improvement is really crazy! Thanks for sharing...
