Naomi Model Extractor is a QuickBMS script that will scan game files for NaomiLib models and extract them.
Exported models can be opened in Blender with Blender Naomilib Importer Addon
-
Obtain your legally own game .GDI file and open it with GD-ROM Explorer, inside you will find multiple files that may contain game models. If you are unsure which file contain models, you can extract them all to any temporary folder.
-
Download your game specific script or Naomi Model Extractor
-
Get QuickBMS and run the script. You'll be asked to open the script, which file to scan and where to extract files.
-
To open extracted models in Blender, install and enable Blender Naomilib Importer Addon
- Where are textures?
Textures are usually stored in separate archives without any header, so you have 2 options to obtain them:
- Dump textures with by using Retroarch Flycast core (please note some textures are vertically flipped, which is correct!)
- Look for game-specific scripts in this section
- No models found!
-
When searching for models in a Dreamcast game, be sure to extract files from GD-ROM explorer first!
-
Avoid scanning Track.bin or files, they are likely using scrambled data and will result on false positives or no models found at all!
-
Files containing models are often referred as "POLYGON", "POL" , "MDL" , "MODEL" , "OBJ".
-
Most Naomi games resources use DES key encryption and are further compressed into zlib, so you'll need to either map the structure or open an issue, asking for X game support
-
Some games use a mix of NaomiLib and Ninja .NJ format, therefore .NJ models will not be detected/extracted.
- Why models are separate into many pieces?
Depends by how they are stored in game, especially character models are often split into several pieces, so you'll have to manually re-assemble them
- I want X game textures/music/sfx
You can open an issue specifying the game you want and if it gets many requests I will give it a look!
