LDD crashes over 40-50 thousand bricks

[Nachapon Lego]

Easy way to benchmark LDD?

LDD is limit by polygons count not by quantity of bricks. I tried to place 48x48 big base plate one by one. LDD crash at about 95 bricks (base plates) only. ( 7.8 million polygons).

LDD2povray can handle many more polygons, This is a 200 big base plates 48x48 rendering test, took 50 min to render. ( 16.6 million polygons)

I also had crash problems when designing my 13-foot Super Star Destroyer. After 41,200, LDD could take no more. I had to design the rest of the monster in halves. Each half containing 35,500 pieces.

On that note, I'm having problems rendering this leviathan. If anyone's a rendering pro, I'd greatly appreciate some help!

What rendering problem? If you're stuck with LDD to POV_Ray converter or using POV-Ray itself, post what error message it shows, and what version you are using (both converter and render) and someone who is imitate with the converter or render can figure out what is the problem.

maybe post your file and someone can check it? Or have him/her render it for you?

I'm going to be away mostly for New Years week, so if I get your file by Sunday evenings EST, I could run it at default setting, high res with transparent background, no AA, and send you the finished image to insert the desired background. I have dual XEON and it renders anything easily in 1/50th the amount of time a cheap Walmart junk would need.

Sure, Lego Otaku! Where can I send you the file?

You can upload files to Bricksafe.com.

If you don't want anyone else being able to download the file, you would need his email

This is the best render I could do so far. It's only 800x600 res but took up 4.5 Gigs of RAM + 4 Hrs render time!

[Calabar]

Four hours is not a long time for a render.

Many builders here take up to "days" for a good render.

If you want to save time obtaining a good result, you can use the bbqqq techinque of separate renderings.

Take a look at here.

Thanks for the link! And you're right, it does take days. I was more shocked at the memory usage. My machine's fairly decent and there were times when the screen just went black for long stretches.

if you don't want to share the file, send it to killua @ tds . net (delete spaces) and I'll get it started before I head out tonight. I haven't used any of bbqqq technique, all of my render were done with plain background and no baseplate so it'd be easier to slip in various background. I'd love to try it sometime for chrome effect but atm none of my moc ever used chrome.

I've been wanting a solution to this problem for a very long time to finish my capital ship build so if someone does come up with a solution please post it.

I'm running:

Intel i7 950 @ 3ghz

12 GB RAM

64 bit win 7

R9 290x radion 4gb

Corsair Solid State Drive running on AHCI.

Crashes when a certain brick limit is met. Would be nice if it used the GPU...

[Fox Hound]

There is no solution. It's a program problem. LDD can't display more than 7.8 million polygons (see post at top of page). But I feel your pain, buddy. On each version of LDD released since 2005, there was a giant capital ship I couldn't design (in one piece). But it's getting better. LDD2 maxed out at 11,000. LDD3 maxed out at 31,000. And now it's around 41,000 pieces. In LDD5, I bet you can take it up to 50,000.

BTW. I wanna see your capital ship. Post a pic!

If you click my signature at the bottom of my post it will take you to my Flickr page. Like you I have to make it in sections as its minifig scale.

Please send your lxfs and let me try. I will try to combine both half in LDD and render. If the combination fail, I will render two images then merge the pictures.

This eight MBs took 18 minutes to render @ 4096x4096 AA. I will render nine MBs together as soon as someone share the Parisian Restaurant.

Sure. What's your e-mail?

That is a nice looking render! What settings did you use in POV-Ray?

[Nachapon Lego]

@Dilvish. To save render time for big lxf.

Model: original LDD geometry

Light: lett 47%, Top 21% no shadow

Radiosity: normal or fast

Sure. What's your e-mail?

Thank you for your amazing LXF. I have no idea how come you can build this moster with LDD.

I have to simplify both side before assembly them. Total 36,000 bricks(4.2M polygons).

I am going make rendering test and send it to you.

It is possible to make a 8K UHD+ resolution (ultra high definition)(8192x8192 AA)(67 megapixels) rendering with notebook PC with 8GB of Ram only!

Thats impressive. I wonder if TLG will ever take this feedback and allow us to create large builds
