DCC production guide

FBX, glTF, OBJ, or STL Export Decision Guide

Direct answer: Choose the export format by the payload you must preserve, not by habit. FBX is common for DCC-to-engine animation and rig handoff. glTF or GLB is strong for realtime web and compact PBR previews. OBJ is simple static mesh exchange. STL is for geometry-only print workflows and should not be used when materials, UV-rich PBR, rigging, or animation are required.

FBX handoff checks

Use FBX when skeletons, animation clips, blend shapes, sockets, or DCC interchange metadata matter. Verify units, axis conversion, baked animation frame range, triangulation policy, smoothing groups, and embedded versus external textures.

glTF or GLB checks

Use glTF/GLB when web preview, PBR material portability, or compact runtime delivery matters. Validate texture paths, metallic-roughness material assumptions, image compression, node transforms, and binary versus JSON packaging.

OBJ and STL limits

OBJ can move static mesh and basic material references, but it is weak for modern rigged game assets. STL carries surface geometry for printing and often drops UVs, hierarchy, PBR materials, and animation. If the receiving task needs those, choose another format.

Round-trip test

Import the exported file into the target tool, compare scale, pivot, material count, animation playback, and triangle count. A file is not approved because it exports; it is approved after the receiver reads it correctly.

Worked review example

A rigged enemy with walk and attack clips should not be delivered as OBJ or STL because those formats cannot carry the animation payload. FBX is the likely interchange choice, followed by an engine import test for skeleton scale and clip range. A product configurator preview on the web may choose GLB instead, because compact PBR delivery and browser runtime support matter more than editable DCC animation curves.

FAQ

Which format is best for animated game assets?

FBX is often used for rigged and animated game-engine handoff, but always verify the target engine importer.

When should I use glTF or GLB?

Use it for realtime web delivery, compact previews, and PBR material portability when the target supports the needed extensions.

Is OBJ still useful?

Yes, for simple static mesh exchange, but it is a poor choice for rigging, animation, or rich PBR delivery.

Why not use STL for game assets?

STL is geometry-only and print-oriented; it usually drops materials, UVs, hierarchy, and animation.
