[1.2-1.7] Blender (2.83+) .mu import/export addon

[taniwha]

Funnel icon in the outliner (top right viewport by default)

[Starseeker]

@taniwha Alrighty, I've gotten the stuff to display and I can select individual parts; however, I can't select things like colliders, which I'm wanting to remove; I'm basically trying to get the models all arranged as they are in the craft, without any of the colliders, unused bits like shrouds, etc.

[taniwha]

Hmm, colliders should be selectable. I need to poke around again, blender keeps changing.

[taniwha]

I haven't looked into the collider issue yet, but I have got the importers working on the most recent versions of blender (git as of an hour or so ago), but other than shaders, I expect the fixes to be good for most versions of blender.

[Lucas3214]

I downloaded the latest branch on Github but I can import crafts.... 

IndexError : string index out of range

[taniwha]

@Lucas3214: please post the stack trace. With what you've given, all I know is that there was an error, no clue as to where.

However, one common mistake: The KSP GameData path (in the addon config panel in user prefs) has not been set.

[Lucas3214]

I think I fixed it, prob because I have Chinese Characters in the file path... @taniwha

[taniwha]

Ah, that might make a mess of things, but it would be nice to know where the error was.

[Ungetoastet]

Pls help, it creates an traceback error when I try to import a .craft and it doesn't actually import it. I want to 3d print a rocket I made.

[taniwha]

I can't help you if I don't see the trackback, other than to suggest that maybe you haven't configured the KSP GameData directory in the addon's config panel (in user->prefs->addons).

I'm having the same problem trying to select the .craft file for import , here's the traceback error:

Also, I did take a look at the addon's config panel and was still not sure which directory slot we are supposed to characterize as the KSP GameData directory?  For me, when I navigate to user->prefs->addons, there is no option to specify a KSP GameData directory?  I only have checkbox options to enable/disable your import/export addon.

Could you be more specific here?

I too went for years without knowing that those bars could be opened into panels. Click on the little triangle on the left end of the bar.

As for the instructions, sorry, I thought I had said something. I will fix that.

[taniwha]

I have export working reliably again on blender 2.80+. It was corrupting the mesh data quite severely for me.

Thanks I got it to work, but you're still really missing a step 9-10 in the OP so folks will know how to get the thing functional.

[taniwha]

well, just what would steps 9-10 be? I'm open to suggestions.

Going back to my previous post where I already suggested it...  you eluded to it with this comment:

"maybe you haven't configured the KSP GameData directory in the addon's config panel (in user->prefs->addons)"  

My gut response to that is, "Well, you didn't tell me in the directions that I needed to do that or how to do it?"

Step 9 would be where specifically to look in blender (user->prefs->addons etc.) to find your installed app.

Step 10 would be your instructions (click on yellow triangle?) to make the input section appear where you can enter the default directory... and then to enter the KSP gamedata default directory

This is not in any way obvious.  Whether that's 1, 2 or 5 steps is up to you... it's just missing from the OP directions.

 

Edit:  oops, my bad...  did you go back and add it as sub-bullets there in step 6?  I don't actually recall seeing that before.  But that seems to be fine.  I just didn't notice it was added.  If I missed it originally, I concede I must be blind.

Those instructions are there now and have been for a week or so (just in step 6).

Ah...  I just didn't notice them at a glance today.  Was expecting something added to the last step.  

All is good!  I did get it to import a craft file.  Now I just need to devise some reasons for why that might be useful to me?  

Appreciate the app, thank you!

[taniwha]

I've started a wiki that is open for editing by any with a github account. Right now, it has docs for installation and craft import. More will come later.

Hello, i install the addon according to instruction in blender 2.82.

When i try to load a craft i get this error:

I'm complete new to blender. I can't identify the problem

[taniwha]

@josselin2196: That looks like the file itself is truncated to 0 bytes (ie, is empty). I suggest double checking the contents of the craft file. However, I do need to work on better error reporting.

[taniwha]

@josselin2196: I'm sorry, I missed this before: the error is occurring while reading configs in GameData, not while loading a craft file. This means there's an empty cfg file somewhere in one of your mods.

[taniwha]

@josselin2196: I've pushed a "fix" for the problem (the config node parser now just quietly bails if the file is empty).

[Micro753]

Blender gave me some errors when I tried to import a .craft file. I'm using Blender 2.82 and the version of this that you updated 20 hours ago. The .mu import works, just not the .craft. I did set the GameData directory, so I'm not sure if I missed a step or did something wrong. I tried with one of the stock .craft files as well, and same thing happened. Only other thing I can think of is that KSP is on D:\ instead of C:\
