Convert FBX to OBJ
Strip your FBX down to a clean OBJ + .mtl pair. Useful when you only need the geometry: CAD viewers, ZBrush, MeshLab, 3D-printing slicers. Animations, rigs and PBR maps are dropped — that's the point of going to OBJ.

Why convert FBX to OBJ?
FBX is a heavy, animation-friendly container. OBJ is the opposite: a 30-year-old text format that does one thing — static geometry — and does it for every tool ever made. When you only need the mesh, OBJ is a smaller, simpler, more universal target.
The conversion is intentionally reductive. Out of an FBX, the OBJ keeps: vertex positions, faces, UV coordinates, vertex normals, vertex colors (some tools support them in OBJ), and material slots written as a sibling .mtl file. Out it leaves: skeletal animations, morph targets, rigging, embedded textures with PBR data, scene hierarchy beyond mesh grouping.
The .mtl file references textures by filename — if your FBX embedded them, you'll get a separate set of texture files written alongside, and the .mtl points to them. Keep all three (.obj, .mtl, textures) together when sharing.

Tips
Common pitfalls
Read these before converting — they save hours of debugging in your engine.
Animations are dropped
OBJ has no animation. Only the bind pose / frame 0 is exported. Need animation? Convert to GLB or stay in FBX.
PBR maps don't survive
OBJ's .mtl spec predates PBR. Roughness, metalness, emissive maps are dropped. Diffuse and normal maps come through.
Hierarchy flattens
FBX scene graphs with nested null nodes get flattened. The OBJ has one or several meshes with no parent/child relationships.
Scale may shift
FBX has explicit scene units; OBJ does not. If your FBX was in cm and you import the OBJ assuming meters, expect a 100× scale issue. Check your import settings.
