[Software] LDD2PovRay

Yes, as I said, this can be done without significant effort.

Now I understand what you mean. Sory for my bad english.

So please consider to add the check box, or let solid color parts/ trans parts (/chrome parts?) have their own slider for adjust their level of detail.

A couple of strange artifacts in my latest render:

I downscaled the full image, but I put pixel-for-pixel copies of the little meshy artifacts in the corners. Any idea what caused this?

Is there some transparent brick? Could you, please, share your LXF file with a relevant portion of the model?

Nothing transparent at either end.

I just got the latest update for LDD and it seems my POV-Ray does not like taking the new changes. Maybe it's just me but if anyone has suggestions I would love to hear them

So what does this error tell you?

Unable to generate necessary includes.

'NO.' is an unexpected token. Expecting white space. Line 5, position 43.

Now, it's entirely possible this is bush-league stuff, but I'm just getting comfortable with my solar calculator, so all this computer stuff makes me a bit dizzy.

'NO.' is an unexpected token. Expecting white space. Line 5, position 43.

This error is caused by 3 parts having wrongly stored name in the new brickset.

Part ID 87799 has name "HEART" WITH 3.18 SHAFT, part ID 85969 has name RIM CASE Ø36.7 "CALLARDO" and part ID 43751 has name MINI WIG MAN "NO. 2".

Problem is with the double quotes. According to XML standard double quotes has to be stored as " and not directly as ".

So instead of designname="MINI WIG MAN "NO. 2"" it should be there designname="MINI WIG MAN "NO. 2"".

That's why you see that unexpected token 'NO.'.

Not even LDD can load these parts and it ignores them.

In previous brickset version these parts were named properly and could be used in LDD without problems.

I will post an update to LDD2POVRay which will also ignore such errors in brickset to avoid problems in the future.

Yep, that's the error I keep getting. Thanks hrontos for the help

[IAmWillGibson]

Ahh, rock ' roll. Thanks!

[glenbricker]

These images are crazy, I am going to have to try this out. I had not idea the images had gotten this good.

Version 1.2.5 was released today.

Changes in this release:

• added Don't bevel transparent parts checkbox as requested by bbqqq
  
• fixed problems with brickset version 835 from LDD 4.3.5
  

Please, let me know, if you experience any problems.

EDIT: changed version to 1.2.5 since I had to rebuilt it.

Hrontos, you always ROCK!

Thank you, it was bit on the fly, so I hope, I did not introduced some new errors.

Hrontos, you always ROCK!

Thank you bbqqq, I hope the requested checkbox works as you expected and reduces rendering time to values comparable with your tests.

Okay, so those worked, and, honestly, a day and a half later, it pooped out this little gem:

Here's the bigger version.

And, of course, I notice now the digital model is missing a piece! Ach!!

Anyway, so would it have taken even longer to render on this steam-powered computer if I hadn't have told it to not worry about the little "LEGO" on the studs?

Nice render and a nice model.

Logo on the studs would make it a bit slowlier, but bevels are the part making it slow, so logos increase memory requirements, but rendering time should not be significantly longer.

Concerning the part you forgot: it is possible to render only a portion of image. Just add to the generated ini file following lines:

Start_Row=2552

Start_Column=4296

End_Row=1936

End_Column=5130

Numbers are in pixels are just an examples. Open you image in picture editor, use some selection tool to draw a rectangle around the portion of the model where the missing part belongs. And take top left coordinates as start and bottom right coordinates as end. Run the render. Only that area will be rendered. Then copy/paste the rendered rectangle into original image.

Very nice tip.

Is it possible to force pov-ray to continue to render previously interrupted render (after reboot or something like that)?

[hrontos]

Yes, just add: Continue_Trace=On to the ini file or +c to the command line box (this is usefull, when rendering directly pov file without ini file).

After purchasing a new laptop (For unrelated reasons, obviously) I can now successfully use this program and am attempting my first render. I do have one issue, however. If I attempt to manually open the .ini in Pov-Ray it will not start to render. Is there something I'm doing incorrectly?

[CM4Sci]

I've been meaning to ask this, but how do you work this thing?

Whenever I click the icon I get a message saying "Output path for includes not entered. Please, enter path where the POV-Ray include files should be stored.

Review and validate also the db.lif path location.

Path shown in the POW-Ray should be added to your POV-Ray include library path."

Huh? I'm sorry if this is like a REAL obvious thing, I'm just not the brightest today. Can someone please help me how to make a render or whatever?

Thanks.

Whatever? Please remember this is an AFOL site.

On topic: have you checked through the topic for your problem? I have a vague memory it has been discussed.

What exactly is not working? After clicking Yes to start render immediately in LDD2POVray the POV-Ray will not start? Or you really manualy start POV-Ray and manually open ini file and click on the Run/Render button in toolbar the rendering will not start. Did you get some error message?

Review and validate also the db.lif path location.

The path to directory where db.lif is stored is prefilled automatically and it is very unlikely that you have to change it.

The output path for the includes can by any directory. I personally have it as a subdirectory named LDDinc in the folder where db.lif is located. Do not specify the same directory as you plan for your models, since it will not work. LDD2POVray will create a few houndred files (more than 500) and they can have up to 1GB so select some location with enough space where that large number of files will not bother you. You will not need to work with these files directly so it really does not matter where they are. As I said, I have in a subfolder stored n together with db.lif.

POVRAY.INI can be opened using Tools menu in POV-Ray. Add following line there:

Library_Path=\\.\LDDIncludes

When I try manually opening it in POV-Ray it will not do anything (Not even an error message) when I attempt to use the Run/Render button. It works fine when I start the render immediately.

I was doing a render in POV using the converter and found an orange peel effect on the underside of part number 45301 (LDD Number).

Looks like a poly is off a little

[Shroud]

I had a question about the horizon line as well if anyone can help. I want to have a blend so there is no horizon line at all, I've fluked it working on one moc but the other (with the same settings) has a line.

What is the code I would need to achieve this?

Ok it was just the camera angle so you couldnt see the horizon line. Is it still possible?
