Models don't import, just a plane and an empty

[ReeceTaylor512]

Been trying to get this addon to work but whenever I do it never imports properly. I just get a plane and an empty

I've added the filepath

And here is what that filepath looks like

[meteorshowers]

the same problem

[Xolverr]

Same problem here

[TobyLobster]

It's difficult to say what's going wrong here. Obviously it works here. I am Mac based, but other people seem to have got this working on Windows too. Are there any error messages that appear?? If anyone who is getting this issue can investigate what's going on, or is willing to help try test builds, I would be interested to find out more so that I can fix.

[ReeceTaylor512]

I don't think so. I'm willing to investigate with you if possible although I'm away for a few days but would be able to when I'm back.

[TobyLobster]

Ok thanks @ReeceTaylor512, let me know when you have some time.

[ReeceTaylor512]

Hey, I'm available now. Where's the best place to discuss this? I can do it here or somewhere else like discord if you prefer

[TobyLobster]

Hi, thanks for getting back. I'm happy to keep going on here.

I attach the latest version (as yet unreleased) without the huge background.exr file that's normally part of the release but is too large to attach here. The lack of this file means it may not give a pretty renders as a result (colours may be wrong) but should otherwise work OK.

A couple of things that would be helpful if you can. Firstly if you could try installing this latest version and confirm if it works or not, that would be good to check. (I suspect the problem is still present though).

Secondly, I don't know if you are familiar with the Command Prompt in Windows? If Blender is started from the command prompt then you can see some debug output when my plugin executes which would be helpful to me in narrowing down where the problem lies. What you need to do is: 1. Open the Command Prompt. 2. Type in the full path to the Blender executable. 3. Press return. Blender should launch. 4. Try using this LDraw plugin. 5. Look back at the Command Prompt for the output.

This might take a few iterations back and forth between us to narrow this down, but if you can, thanks for your help.

I get this issue too on Windows 10. Some helpful info: on windows you don't need to run blender in cmd to see debug logs, you can toggle the cmd shell inside Blender with Window > Toggle System Console.

Here's a log of me attempting to import the attached LDraw file (canetest.zip):

The LDraw Parts Library path to be used is: /Applications/Lego/Bricksmith/ldraw

I'm not familiar with how this works, but it looks like the issue might be that it tries to point to the wrong directory for this library on Windows. I'll do some snooping for the Windows path and edit the respective script to see if that fixes my issue.

[Vap0r1ze]

After a little snooping it looks like the issue I'm seeing is that when you upload releases you are uploading your personal ImportLDrawPreferences.ini file along with the add-on bundle. I deleted this file and let it regenerate, and now I've moxed onto a different issue (progress!)

[ReeceTaylor512]

Yeah sorry it's been a while for me life has been busier than expected. I did manage to test the importer with a model from Stud.io and the same model from LDD and what's strange is that it imported from Stud.io but not LDD

[JHubi1]

Hi! Just wanted to ask if there is any solution. I'm using Studio 2.0 and the following error is occurring when I try to import a model. I even had to make a screen record to capture it (it disappeared that fast). The log says:

[ReeceTaylor512]

Working fine for me with studio models. Having an issue with LDD parts though.

@JHubi1 are you sure you added the right path to the LDRAW library?

[JHubi1]

No, sorry, I wasn't into it at that moment, after a bit of trying around, I was able to make it run. The path was set wrong, so easy it can be 😅

Would like to bring up what I wrote again, it seems to have been forgotten

[SaffronStreams]

I had the same problem as described here, but after reading some comments and rereading the install instructions, I realized I had misunderstood the "Setting the LDraw Parts Library directory"instructions.

Where it says "Type the full filepath to the 'ldraw' directory you unzipped to." I thought it was a way of saying "navigate to where you have the library and import one of those files", but it's actually the path you need to set under import options, you're not importing anything at that time, you're just setting the path. Once you set it there, it does seem to remember it, so that's nice.

With that path set, you can now navigate to where you put your ldr file you wanted to import, and import it, making sure your ldraw filepath is set to the library. I did still have missing hair, but everything else seemed to have import the way I wanted it to

Thanks @Vap0r1ze Your fix worked for me in Blender 3.6 with v1.18 of the addon.

[TobyLobster]

I have just released a new version fro Blender 4 that should fix this issue.
