Why will my part not appear?

[Vectura]

I have made simple part mods before, and I simply can't think why it won't appear!

Link to the mod so far: https://www.dropbox.com/s/t72evdvb5zsynn3/VramJet.zip?dl=0

Also, can anyone suggest changes for the atmo curve and velocity curve bit to make it act more like a ramjet/scramjet?

Part files aren't enough to diagnose this problem.

Have you checked the logs for error messages?

[Vectura]

Which log should I be checking? How to bring it up? Or do you mean a file?

[CaptainKipard]

output_log.txt in KSP_Data

[Vectura]

Well, in KSP.log I found:

[WRN 15:45:54.365] Model load error in 'C:\Program Files (x86)\Steam\steamapps\common\Kerbal Space Program\GameData\VramJet\Parts\Engine\ramJet\ramJet.mu'

Output log had this:

Model load error in 'C:\Program Files (x86)\Steam\steamapps\common\Kerbal Space Program\GameData\VramJet\Parts\Engine\ramJet\ramJet.mu'

Dunno why. Outdated Unity or something?

The full error is

It seems you model was not properly exported. How did you create the .mu ?

[Vectura]

Right, I jsut tried something else, and it didn't work. I have a ramJet gameobject, that is the parent of the ramJet model, that is the parent of a thrustTransform gameobject. I added the Part Tools component to the first gameobject. I gave it the model name of ramJet. The file URL is in the part folder of my mod on my computer. The texture format is MBM (DDS was not an option).

[CaptainKipard]

Show your hierarchy

[Vectura]

What hierarchy? Unity? Files?

[CaptainKipard]

In Unity there's a panel called Hierarchy with your objects in a hierarchy.

[Vectura]

ramJet gameobject > ramJet model > thrustTransform gameobject

[CaptainKipard]

Umm. That doesn't really help sorry. I was really tired when I asked for that. I don't know what I was thinking.

Do you have an animation applied to any of the objects in that hierarchy?

Also why is there a space in "Je t.mu"?

[Vectura]

On my local copy there is no space. I will update the dropbox one now. No animations.

[CaptainKipard]

:/ ... ok but in the log there is.... You're making this really difficult. Please keep up.

[Vectura]

Keep up? What do you mean?

[CaptainKipard]

OK...

Answer questions directly.

I asked why is there a space in "ramJe t.mu" in the log snippet you posted, and you responded with "there's no space your local copy". Do you mean in your log, or in the part files? Was that a typo? How would that space get there in the first place? It's on BOTH LINES. That leads me to believe that the game is looking for a file with a space in the name for some reason.

[Vectura]

I meant that in my local copy of the mod, ramJet.mu does not have a space in it. It didn't in the config file either.

[CaptainKipard]

Try to rebuild the hierarchy from scratch.

[Vectura]

Sorry for a late reply, but I assume you basically mean remove it from unity, re-import the model and set it up again, then re-export? I'll try that this evening!

[CaptainKipard]

Yes. I've had models not appearing once, and redoing everything worked. It might be easier than trying to pin the problem down.

Sometimes its something as silly as setting the wrong shader too

[lo-fi]

The part failed to export correctly. Always check the console log in Unity!!!!

Model load error in 'C:\KSP_win\GameData\VramJet\Parts\Engine\ramJet\ramJet.mu' 

This means that the .mu file ended before KSP expected it to - it's incomplete. Which in turn means that PartTools bombed out before it finished writing the file.

It's often caused by having a mesh collider, mesh renderer or similar assigned to a GO without a mesh filter. Borked animations can also cause this, but check for rogue GO's first. As LordPrometheus pointed out, it can also be a material that hasn't had a shader properly assigned. Either way, something is stopping PartTools from exporting it correctly.
