I created a LDD file with 128k parts (all 1x1 tiles) at which approx 2GB of RAM where used. It worked but was painfully slow. Doubling to 256k crashed it on my computer. I could even use the LDD explode functions :D If anyone needs the file: https://raw.githubusercontent.com/sttng/LDD/master/128k.lxf

Someone should really check if LAA patch does something. I am on macOS so I can’t try myself. I wouldn’t even know if macOS needs/supports LAA for 32bit applications.

Performance and maximum number of bricks not only depends on the quantity of bricks placed, but the complexity of the geometry of the parts and the scene (ie 1x1 tile vs more complex parts like for ex. gears). Transparent bricks will also be more intense to render. In LDD, under preferences you can also disable high-quality rendering of bricks in the scene view and bricks palette, reduce the complexity of shading, remove brick outlines or increase the compatibility mode to improve the performance which could increase also the stability and the number of bricks used. I read somewhere that a guy could place 100,000 1x1 tiles in LDD when it used approx 1GB of RAM and got super slow. But that was in 2015.

I guess then your computer should be also checked for if RAM and/or HDD working correctly. I have used LDD quite a lot and (knock on wood) so far didn’t have any corruptions. But I also tend to create multiple (sequential) versions of files (not only LDD - but also Excel, Word, ...).

LDD max parts depends much more on your graphics cards RAM then the RAM of your Computer. Also the size of the scene will affect performance (for ex. 2 parts which are very very far from each other perform worse then 200 parts next to each other)

Just wow !

Further (sad) Update from LEGO Support: In regards to whether LDD works with macOS 10.15 Catalina, I am sorry to let you know that we no longer support it anymore. However, alternatively, you may head to the link below to see what are softwares can be used which supports LDD: https://www.lego.com/en-us/ldd/download

Reply from LEGO Service if they will update LDD for the new macOS: Thanks for getting in touch with us! LEGO® Digital Designer, or LDD, is an amazing program that allows you to build models virtually. We're so glad you enjoy using it! LDD was first made available in 2004. It has seen many changes and updates over the years. Although we won’t be providing any major updates or revisions to the program in the future, we’ll continue to update the palette and to make sure it runs smoothly on current Operating Systems. We can’t provide a timeline for palette updates or error fixes, but LDD will check for a new version each time it’s launched as long as you’re connected to the internet. If there’s an update available, you’ll be prompted to download it. For more information about LDD, please visit LDD.LEGO.com. We want to make sure we're doing a good job for you, so you’ll always find the link to a four-question survey in our emails. Please tell us how we did today: LEGO Survey link Please let us know if you need anything else. Kind regards,

Thanks a lot that would be nice. I am convinced it’ll stop working but better to give it a try.

Anyone tried out the new macOS 10.15 Catalina developer preview and LDD already ? I expect LDD won’t work anymore but maybe someone can confirm ?

Very impressive!

https://github.com/sttng/LDD/blob/master/pyldd2obj.py tested on macOS Mojave and Python 2.7 Usage: pyldd2obj.py test01.lxf out_obj_file Not by me but by jonnysp - I only did some backporting from Python 3 to 2.7 and added UTF-8 support. Converts LDD lxf files into Alias|Wavefront obj files including mtl files and png textures.

I use this to process lxf (=zip files) and read the lxfml file in my python scripts archive = zipfile.ZipFile(lxf_filename, 'r') lxfml_file = archive.read('IMAGE100.LXFML') tree = ET.fromstring(lxfml_file) Of course you need to import zipfile and ElementTree

A kind of hybrid render I did:

1) Yes thats correct. But aren;t user anyway linking to external sites for lxf already (brickstore, mocpages, etc) where another, non-forum account is necessary ? 2) OK I get that point.

@Calabar But this could exactly work with github. We ask ppl to put their creations on github and then there is a master git which is maintained by forum admins. As part of the maintenance admins could put ppls creations into the master github.

Maybe we should move to GitHub for hosting the lxf files ?

Improved texture handling:

First success with textures - but is all really alpha stage

Is this file (LXFML5.zip) still available somewhere?

Add support for Transparent colors and Multi-colored solid parts (that is parts which consist of 2 plastic molds - like the bold hair piece). I got internal groundwork done for texture support.

Cool. I like it. Even so personally I would like lxf support as I am not using ldraw.
