| New Blender Importer/Exporter for Blender 2.82 |

After months of work, I've released my Blender LDraw handler. https://github.com/cuddlyogre/ExportLdraw
Download the project zip, and extract the contents to C:\Users\username\AppData\Roaming\Blender Foundation\Blender\2.83\scripts\addons\ExportLdraw, then in Blender, go to Edit > Preferences > Add-ons > search for LDraw and check the box next to Import-Export: Export LDraw. Menu options are in Import and Export.
Please install it and show me what you can do.
I need to write up proper instructions, but here's the readme :
Code: LDraw Handler for Blender 2.82, written by Matthew Morrison [cuddlyogre] - [email protected] - www.cuddlyogre.com
Materials were taken almost wholesale from https://github.com/TobyLobster/ImportLDraw. I added my own glass material that was taken from a BlenderArtists thread, but most of it is unchanged. I essentially learned Python by dissecting and studying this plugin, and it inspired me to make my own. My plugin wouldn't exist without this one.
I have to write up actual instructions, but normal usage is straightforward.
Importing: File > Import > LDraw (.mpd/.ldr/.l3b/.dat)
Exporting requires a bit of setup, but once that's taken care of: File > Export > LDraw (.mpd/.ldr/.l3b/.dat)
I have a few parts in the official parts library that were created in Blender and exported using my plugin.
You are able to export parts and models with the correct project setup. You can even build entire models in Blender, but the workflow needs to be figured out for that to be any kind of fun.
I built this plugin with performance and compatibility in mind. It handles MLCad parts, LDCad projects, ldr, and mpd. It also processes most official META commands. For instance, STEP will set keyframes so you can watch the model be built. Theoretically, you could build and entire animation in an MPD file if you did it right. TEXMAP support is really all that's missing feature wise.
https://omr.ldraw.org/files/337 loads in about 13 seconds https://omr.ldraw.org/files/338 has lots of incorrectly written parts and MLCAD parts that import correctly
You are able to choose the logo you want to show on studs, or no logo or stud at all.
It works with Eevee and Cycles right out of the gate.
On my TODO is the ability to replace selected parts with different resolution parts. For instances, 338 from eariler has a lot of gaps in the tires and fender because the model is built with parts with different resolutions.
Pull requests and examples of my plugin in action are welcome. |

Aloha 
i just wanted to say hello. Last weekend, i stumbled across your LDraw library and it´s viewer, and even more it´s export function, and it was quite fascinating. Especially that this allowed me to import your models into my 3D Program (an ancient Cinema 4D version) to render some pictures.
Ok, later i discovered, that the export function from LeoCAD (specifically it´s Wavefront .obj format) is more compatible with C4D in regards to how the objects get exported, but whatever.
So, as a welcome, here are some fast testrenders from some of your models:
Ok, some materials are still off, especially every transparent material gives me headaches and way different results than what i have seen in some of your POVRay images... but thats something, that i hopefully can figure out at some point.
And while i was at experimenting, since i got those models into C4D, it was also possible to send them to the Free for all Unreal Engine 4  (again, materials are far from perfect and it´s just the plain boring start scene without anything interesting). If you ever want make your own LEGO game, UE4 (soon UE5) might be worth taking a look:
Some questions if you don´t mind:
- Since i am tempted to make some more renders, or even a short clip with UE4, how exactly do you want get the credits inserted, and what exactly should those credits contain? I mean, it´s your LDraw library and tools, that made those renders possible.
- As mentioned, some colors are way off. Is there somewhere a kind of library, or info, how i can those colors closer to the originals? Or do you think, they are decent enough?
Have a nice day.

| LDView 4.4 Beta 1 test release |
|

I have posted a test release for LDView 4.4 Beta 1 to GitHub:
https://github.com/tcobbs/ldview/release...v4.4_Beta1
This release fixes a number of problems that were found in the previous Alpha 6 test release. However, it is still a test release.
The 32-bit Windows installer is forthcoming. (No one asked for one of those for the Alpha 6 release, so I'm not sure how many people would use it.)
The ChangeHistory.html file that is included in the release lists all of the changes since LDView 4.3. In the macOS version, ChangeHistory.html is in the dmg. In the Windows version, ChangeHistory.html gets installed to wherever you install LDView (C:\Program Files\LDView by default). I'm actually not sure where it goes in the Linux version. Please see the Alpha 6 announcement linked above for a list of what I feel are the most important changes relative to LDView 4.3. As mentioned, this Beta 1 release fixes bugs found in Alpha 6.
Please let me know about any problems you find. The preferred way to do that is with LDView's GitHub Issues tracker. However, if you do not want to create a GitHub account so that you can do that, you can reply to this message.

| [LPub3D] Strange behavior with Unofficial and Custom Parts |

First off, has anyone heard from Trevor? I noticed that he hasnt been online in a few months.
Secondly, I am having all sorts of trouble with the PLI and assembly images resolving correctly.
I have a model created in Studio and saved as an LDR. I know that this used to be an issue for LPub3D but I had seen that Trevor had added this functionality at some point late last year.
From there I use a LOT of custom parts in my trains. I have tried going back an using the portable versions for windows all the way back 2.3.10 and have had issues with each one.
The cleanest example is that when I use 15335p03 it will show in the assembly but not the PLI.
I am a bit lost and a bit frustrated.
I have also made sure to follow the advice here for custom parts:
https://forums.ldraw.org/thread-20962.html
I have attached a screen shot of the step with 15335p03

She says "kawaii (cute)" for the mini-dolls and Lego is one of her favorite things.
Of course I cannot afford every sets, so I'd like to build Friends, Disney Princess, Elves and DC Super Hero Girls sets in LDraw.
Some of them are built by Philo and in the official models thread
https://forums.ldraw.org/thread-13605.html
https://forums.ldraw.org/thread-22103.html
As there are a number of missing parts in the parts library, I'll list up them here.
Needless to say, I'd like to author them as many as I can, but I'll be pleased if the community helps.

Hello! New to this forum but not to Lego.
I'd like to save images of pieces / builds at various angles. The SAVE command seems to be what I want, but I can't seem to make it work.
I've created an .ldr file like this:
1 16 0 0 0 1 0 0 0 1 0 0 0 1 3001s01.dat
0 SAVE
0
but when I load it into leocad, it doesn't seem to do anything. Any help would be appreciated. Thanks

I'm working to create a documentation sub section of the main site. I don't remember who did the one you see at the top of all of our pages. If the original author or someone else wants to create new colors for us that would be great:
Currently we have:
Red: Centralised LDraw Resources
Blue: LDraw Discussion Forum
Green: LDraw Parts Tracker
Yellow: LDraw Parts Requestor (Not in use)
I'd like three new ones:
LDraw Wiki
LDraw Documentation
LDraw Official Model Repository
Note the "tm" in the upper right corner. That is required. Colors are up for discussion. I'd like the final product to be as close to the original as possible. Any substantial redesigns will be entertained but they will also need to be discussed by the community at large. The final product needs to be fairly high resolution as I'm looking to do printed material (like new LUG banners) as well
Will also need new favicons and just the fade-in brick in the new colors.

I've been doing a lot of tinkering with the main site templates recently. Mostly to streamline the HTML and sync the templates between the Main site and Parts Tracker better (Right now if I want to make a change across the PT and Main site I have to edit like 4 or 5 different files, I'd like to to be one or maybe two).
If something looks broken, it probably is. Check again a little bit later and if it's still not fixed, post here to let me know.
