Chaseconv

Chaseconv is a fast and simple 3D asset converter for Grand Chase. It can convert 3D assets from the game into GLTF files and vice-versa.

Download

You can download the application in the Releases Page.

Using the program is straightforward:

Drag and drop the desired files onto chaseconv.exe (they should belong to the same model!).
Select the format you want to convert the files into.
Select the output folder.

Here's a small demonstration:

There are limitations, however:

You can't export a standalone animation to GLTF. You can only export animations alongside models because joint data is stored inside P3M files.
Some animations may lose data when being exported. That's because some models have fewer joints than their animations. So the extra animation channels end up being discarded.

All bones of the model should be named "bone_X", where X is the index of the bone (e.g., "bone_0", "bone_1", ...). The root bone should be named "root".
Bones should have no rotation in the bind pose. When importing GLTF files into Blender, make sure to set the bone direction configuration to "Blender".
Regarding animations, the bones of the model only support rotations, whereas the root bone only supports translations.
Only the first skeleton/skin in each GLTF file will be taken into account.

Looking for a specific feature? Feel free to leave a pull request. Some opportunities for new features are:
- Add a command-line interface (CLI) to make mass-exporting files feasible.
- Add support for other data formats (COLLADA, OBJ, etc.).
- Relax some of the restrictions on the imported models.
