Unity of Command Forums

Hi all

I've been trying to create a 3d model mod, following the guide on steam, but it's not working. It's creating the empty mod folders for the package, but doesn't create any models or textures or anything.

The error msg I'm getting is:


I'm using a tank model from the web, merging it into body and turret (so maybe the turret is turning the way the german tanks are) and exporting as .obj with Blender.
I exported all textures as .tga with both Krita and Gimp. I don't have a specular map, so I first ignored it and later exported the diffuse map as grayscale. Both didn't work though.

Since this didn't work, I tried to copy-paste the example .yml from the guide and also created a nonsense .yml, which both return the same error as long as the .yml's name is correct and it has a "materials:"-body. Which makes me think maybe the script is at fault here. But in that case, others should have discovered this bug too, right?

Do you have any advice what else I could try?

Hi, please post the yml you are using.

That guide has problems with formatting, I will check to make sure your yml is correct for our importer.

Cheers!

I couldn't attach it as .yml, so I'm posting it as .txt (probably because it could be a virus).

My folder structure looks like this:


My command line looks like this:


I'm using Windows, so maybe it's just some Linux-Windows-thing like the new-line-character?

Thank you for your help

I have edited the can_arm_43.yml file for you.

Note the minus before map_Kd, and how everything that follows is indented by exactly two spaces ("materials" should be a "list" in yml syntax).



There could potentially be a further issue, with the OBJ file: if this still doesn't work, rename the OBJ file to can_arm_43.obj and remove the "mesh_file" line from the yml.

Let me know if this helps.

Cheers!

It did indeed help and you were right with the .obj. If I name it anything but can_arm_43, I get this error:

The "mesh_file"-line doesn't matter; if the .obj file name matches it works.

Next I got this error:


Turns out I was able to fix it by merging the body and turret mesh of my tank. I'm still getting a warning, but at least no more errors:

Sounds like something I can fix.

Now behold the new canadian 1943 tank model, codenamed "Godzilla":




The scaling and shininess is obviously way off, I'll have to play around with it a bit and will probably post another picture with better settings in a couple days.

At least the model made it into the game thanks to your help .

Fixed the scale and added localization, .yml and thumbnails so I could add it as a new unit and not as a replacement:


Now all I have to do is repeat this process for 10 other units and I could release it as a mod

Awesome!

A single-mesh tank will work just fine. If you want the turret to rotate as it does for the other tanks in the game, the OBJ needs to contain exactly two meshes: one named "body" and the other named "turret". It's not always easy to force 3D software to assign these exact names - if it comes to worst, you can always edit the OBJ file, it's just text.

Cheers!

Sorry to respond, but could you possible help me as I'm having my own problem since you've seem like you managed to get a model to work. I'm trying to add in a 'uk_arm_44" unit but it keeps making an empty folder much like your first post.

1. Create the folder path "Unity of Command 2\assets_in\unit_models\uk_arm_44"
2a. Place my model "uk_arm_44.obj" into the "uk_arm_44" folder
2b. Placed textures:
a27m_Cromwell_dd.tga
a27m_Cromwell_Ks.tga # I don't have a spectacular image so I just copied my normal, idk if that's a problem.
a27m_Cromwell_n.tga
2c. Created uk_arm_44.yml with the code:

3. Create a Prep.exe shortcut and changing the Target line to:
"Unity of Command 2\prep.exe" models uk_arm_41 --package=uk_arm_44

Hi Sterling

Sorry it took me so long; I didn't get a notification and wasn't on the forums for a while.

Not sure, why it didn't work for you though. Some points which might point you in the right direction:

- I didn't have a specular map neither, that's why it looked so horribly shiny. In the end, I just didn't include one, worked anyway.
- I didn't use tabs in the .yml file, but added white spaces with the space bar: One space after the '-' and 'map_Kd' and two spaces in front of all the other lines of materials.
- It worked using Windows, the devs use Linux afaik, so shouldn't be an OS-thing
- prep.exe does create a log file in the AppData/local/.uoc2 called prep_log.txt, it's best to have a look at it.

Edit:
- I used cmd directly and not a shortcut, worth a try too I guess.

No problem, I wouldn't assuming you'd be on this forums to check frequently.

From your response it might be due to me using a shortcut. I'm not familiar with cmd so I assumed it had to do with shortcuts. I tried clicking the prep.exe but that ends up closing right after opening.
