Support FBX/GLB for 3D Characters to Reduce RAM Usage

[TheFighterSFMK2022]

Is your feature request related to a problem? Please describe.

Currently, using 3D models rendered as sprites (SFF) causes very high RAM usage. When loading or saving characters in IKEMEN GO or MUGEN, memory usage increases significantly, sometimes reaching 16GB. This causes unexpected crashes and makes testing characters difficult.

In one case, I even lost all sprites while saving due to running out of RAM (I only had 8GB at the time).

I already tried:

Reducing sprite size
Removing unnecessary animations
Optimizing files
Using sprite sequences (0 to 5 then back to 0)

However, the issue persists, and smooth 3D animation becomes impractical or unplayable.

Describe the solution you'd like

I would like to suggest supporting 3D characters directly using formats such as FBX or GLB, similar to how IKEMEN GO Nightly supports 3D stages.

Possible solutions:

Support FBX or GLB models
Direct 3D animation playback
3D character editor (similar to Fighter Factory but for 3D)
Reduce dependency on SFF for 3D characters

This would avoid:

Rendering animations in Blender repeatedly
Excessive RAM usage
Performance issues with smooth animations

Additional context

Additionally, Fighter Factory 32 (4.5.6+) introduced black line issues when generating PCX files, making the workflow more difficult.

Additionally, I'm experimenting with replacing SFF files with 3D models in Unity as a proof of concept. This is to create my own fighting game and modify this Unity project. This video is simply an example of what the idea will look like in Ikemen_Go.

Since IKEMEN GO already supports 3D stages and WMV videos, supporting 3D characters could be a logical next step.
