New official tools + parts released via Unity

[jamesster]

LEGO and Unity recently co-developed a "microgame"; a tutorial on how to use the Unity editor:

It's a pretty cool little intro to gamedev, but it also makes use of some official Unity packages made by LEGO that can import and optimize models.

It currently supports .LDR and .LXF/LXFML (but only version 5.6 or higher, which is newer than what the last version of LDD exports, so currently you have to import LDD models into Studio, then re-export as LDR).

It has quite a lot of optimization features; too many to screenshot and explain here. You can see some of the menus for them in the pics above. There's even some basic support for snapping pieces directly together in Unity.

The brick library contains both "legacy" and "new" parts. These seem to effectively be two brick libraries - the legacy parts are what LDD was using (plus parts it didn't have), with studs and tubes fused to the rest of each brick model. The new parts seem slightly cleaned up, and have studs as separate meshes. The tool is also capable of dynamically adding bevels to all bricks, depending on the LOD setting.

Either way, there's a ton of new parts in here, even Duplo elements:

I'm not really sure what the rules and limitations are when it comes to using these packages - I think LEGO mostly anticipates them being used along with the Microgame, though you can easily add them to a new project and use them on their own. The included terms of service seem more focused on the Microgame aspect.

It's still in beta, so hopefully there's more to come?

This could be the groundwork for a new editor, I would prefer that instead of studio replacing LDD.

[SylvainLS]

Well, the LDD version number is another proof  (if that was needed) LDD is still in use and updated at LEGO but that’s the “pro” version.  If they never updated LDD it’s because it’s difficult to dumb down the pro version and keep both versions up to date.  (And the last LDD updates weren’t up to the “only the best is good enough” motto, even without talking about 4.3.12.)

I’d also note that Studio is based on Unity and that LEGO/BL is looking for an experienced Unity developer (LEGO/BL because advertised on BL, Studio’s forum, and posted on LEGO.com).

So I wouldn’t expect LEGO to give us a LDD-NG anytime soon.  (But I like surprises.)

This unity release is indeed interesting. A couple of observations.

1. New parts geometry come as FBX files. The Autodesk FBX file format is a popular 3D data interchange format utilized between 3D editors and game engines (like Maya, 3DS Max, and engines like Unity, Unreal Engine)
2. There are 3084 new parts within the release I downloaded
3. Parts come with CollisionBox and Connectivity Info in an xml file format which is quite similar to the one used by LDD in the Primitive folder

I include an example of Duplo part 87316 xml file (Duplo Sheep from the picture above). So maybe we can get Duplo parts (including connections) into LDD

Duplo parts seem to use connection type 36 (for their big studs).

Last but not least the info box you get when trying to import a LDD file:

Meanwhile I don't think 5.6 is referring to LDD 5.6 but rather to LXFML file format version 5.6. Currently LDD 4.3.11 uses

Eh!  You’re right, it’s familiar.  I’m sure I’ve seen it somewhere.  But where?  
(They could have used a more recent version though….)

More seriously, the LXFML format have changed through the years.  I don’t have any knowledge/example prior 2014 but there’s a schema (here and on lugnet I think?) that actually doesn’t describe the format used by LDD 4.  5.6 must be the format “in-house LDD” uses now.

[M2m]

I used the FBX files and the accompanied xml file to convert the Duplo 2x2 brick (3437) into LDD.

https://github.com/sttng/LDD/tree/master/NewParts

You can directly import the fbx file into blender and have to adjust the scaling to 1.00 (it was 0.0010 or something defaulted with my install) and export as .OBJ file. Then you can use polymakers brickstudio to convert this into .g file. I edited the xml file with notepad to match LDD format.

Caveat: Duplo parts connect to each other, but Lego and Duplo parts don't connect :(

The FBX parts have studs and tubes as separate meshes as well as the areas which can be textured or could be differently colored (Called DecorationSurfaces and ColorChangeSurfaces) all in one file. I am pretty confident LEGO internally has an LDD version which uses FBX files directly instead of .g files for the geometry or possibly a Maya Plugin.

Also Lego has an internal main brick library (VME tool), which has bricks in highpoly-geometry aimed for Box rendering and advertisement materials and lowpoly-geometry aimed for games, app, etc.

Technically FBX files support multiple LODs (Level of Detail), so I guess these files could have High Quality and Low Quality versions within the same file.

@polymaker would be awesome if brickstudio could read fbx files directly.

Do Duplo bricks have connectivity to standard bricks in the Unity software? Maybe the connection type was altered for regular bricks?

I have to check that. In fact i found the unity software quite confusing and couldn't even find the bricks inside unity.

But i checked the xml files for brick 3001 (2x4) and the connections look exactly the same.

3001 - new Unity version:

What could be done, just thinking out of the box: add the Duplo brick twice, but one version has regular brick connection data on its top. Since Duplo bricks are mainly used for quick fillers.

[polymaker]

@M2m I had the idea that the library I was using did not support FBX but I checked again and it looks like it is supported.

I don't have any FBX files at hand to try but when importing choose "All files (*.*)" and then select an FBX file to see if it works.

Yeah this indeed works ! So it should be rather easy to convert some of these fbx bricks into LDD .g files with your tool !

OK I have identified the following parts which are not in LDD so far but for which there is geometries and xml data in the 'unity pack' - a whopping 1054 parts:

@M2m...and where are these files located? I installed Unity and started LEGO microgame, but I can't seem to find anything...

[M2m]

I'm on macOS and there are 3 zip files in the folder:

/Users/m2m/MyFirstGame/Library/PackageCache/com.unity.lego.modelimporter@3.0.2/Data 

• CommonParts.zip
• LegacyParts.zip
• NewParts.zip

NewParts.zip contains all the new stuff.

Not sure where this is on Windows but I'd search for these zip files.

Thanks! On Windows, it's in the same location: C:\Users\Philo (etc...)

Hi,

I installed unity and launched the lego minigame but I cant find the lego bricks to start building.

Also that gear is not a real lego part to my knowledge right?

I think the gear is from a Dacta set of LEGOeducation set.

[SNIPE]

Does anybody know how to get the parts working in ldcad on windows?

[Philo]

Tried that yesterday, but the pipe is long (and information is lost in the process, resulting LDraw parts that have no edge lines!):

• Find the fbx in the right folder (or export part with minigame)
• open the fbx in Blender
• Set scale part to 25 (when you open fbx, scale is 0.01)
• Export to STL ascii mode if you can (for some reason, my Blender crashes on me when I do that!). Otherwise export to obj and use anoter tool to convert obj to stl ascii, eg. meshmixer
• convert stl to ldraw using stl2dat.

Clearly we need a proper .fbx to .dat converter!!!

[SNIPE]

I still can't find the parts in order to build in unity I just see small builds and textures, sounds, etc.

Does anyone know how tot find them?

Also I looked at the dacta duplo gears and those are different. this one looks like a 40 tooth gear but bigger and with exra pin holes.

That gear does not exist as a real LEGO part but it was made digitally for The LEGO Movie, it forms the rear wheel of this bike in the film proper. I can't link the exact post but about 2/3 of the way down page 2 of this thread there's a cutaway view of how it's used:

Looking forward for these parts to be in ldraw/ldcad.

Certainly can be done also !
