FBX 3D model texture flickering usually stems from texture coordinate issues, shader incompatibility, or rendering setting mismatches.
- Overlapping UVs confuse the engine about where to place textures, causing flicker. - Incompatible shaders (e.g., outdated or mismatched types) create display glitches. - Incorrect mipmapping or anti-aliasing settings make textures flicker when the model moves or scales.
If fixing UVs or updating shaders doesn’t help, try power-of-two texture resolutions (like 512x512) — this often reduces scaling-related flicker in most 3D software.
