Tutorial: How to make a custom BMD model in LM (WIP)

[Lukie D]

Hello!


Today, we are going to turn the Luigi's Mansion coins into Luigi's Mansion GameCube disks.

Why?
Because we can. And also, with making a custom ROM hack, you may want to add custom models to fit your story.

Requirements:
- Bdl2Bmd
- Obj2Bdl GUI
- Bmd View 2.0
- Your Root Folder
- And Compression/Decompression learning

We are going through this with my model already made.

Specs are here:
- Model Textures needs to be .bmp files at 24 bit.
- Model needs to be triangulated
- Model file size should be no more than the model you are replacing.
- Model should be about the same scale size as the model you are replacing.

---

Step 1:
Get your model ready.

Step 2:
Save it as an obj file.

Step 3:
Use Obj2Bdl to convert your obj file to bdl.

Step 4:
Run (by command line or batch file) Bdl2Bmd to convert your bdl file to bmd. Then rename it to "coin.bmd"

Step 5:
Go to your game folder ("game_usa" for NTSC, "game_(language)" for PAL, and "game" for Japan) and go to "kt_static" and replace "coin.bmd" with your new "coin.bmd" file

Step 6:
Recompile your game folder & recompile the root folder, and you should have disks instead of coins popping around.

And... I'm probably going to sound like a noob but. What does it mean to have your model "triangulated?"

You know on Blender or whatever you use has the polygons looking square? Well you need to set them to be triangulated with a setting. (I don't know what model editor you use, but I can help you out with Blender)
EDIT: Let me clarify a bit more. You just need to change your polygons/faces so they are triangulated. If you are using Blender, just select your model, change your mode from "Object" to "Edit", make sure you have all your polygons selected, click on "Mesh' at the bottom left corner of the screen, then go to "Faces", then select "Triangulate Faces".

oh and i kinda need the coin model for a base to start with. could you export to .obj if it isn't a bother?


EDIT:nvm. i got it. Oh and I once found an option to decrease the poly count in edit mode but I can't find it anymore. Can you help please?

do you have anything for converting Bmd to obj?

[~Scary Basher~]

The bmd viewer can export in 3ds and then blender can convert it.

Your talking about the Max thing right?

[~Scary Basher~]

Yup. Blender can use the 3ds max files and export them as .obj

[TheHappyFaceKing]

how douse this obj2bdl program?

[~Scary Basher~]

You have to set up the model in blender. Make sure the file size isn't to large, size of model is the same of the one you're replacing and apply all the textures and save as .obj and use obj2bdl to convert it.

[TheHappyFaceKing]

not to be mean but just saying and use obj2bdl to convert it isn't very informative, what I asked is how to use this obj2bdl

[~Scary Basher~]

You have to click the .exe and find the .obj file you wanna use and then chose your save destination of the .bdl and convert.

Step 4:
Run (by command line or batch file) Bdl2Bmd to convert your bdl file to bmd. Then rename it to "coin.bmd"

I have Python installed. I attempted to run bdl2bmd.py in command prompt and received this error:

| Traceback (most recent call last):
| File "C:/Users/btayl/Desktop/Luigi's Mansion HACKING/Tutorial 1/BDL2BMD-0.1/bdl2bmd.py", line 63, in <module>
| fi = open(sys.argv[1],'rb')
| IndexError: list index out of range

Is there something I'm doing wrong? I have no clue how to fix it.

I've been having the same problem for a long time...it may be the version of python you're using.

Hmm, ok.

I tried following a different tutorial on YouTube that used the "Luigi's Mansion Parameter Editor" by Spacecats - sadly the exe file it is no longer accessible on the internet (since smsrealm.net is now dead). The source code is online, but it requires installing C# just to get the program to work.
