Why convert PLY to OBJ?
Edit scan meshes in DCC tools
Blender, ZBrush, Maya, and 3ds Max all read OBJ natively. PLY support varies — OBJ is the safer import format for editing.
Sculpt and retopologize scan data
ZBrush and 3D-Coat prefer OBJ for sculpting and remeshing. Convert PLY scans before sculpt cleanup workflows.
Add materials and UVs
PLY has no materials or UVs. Convert to OBJ to get a format that supports both — add them in Blender and re-export.
Tips for PLY → OBJ
PLY vertex colors carry over
If your PLY has vertex colors, Fast3D preserves them as OBJ vertex colors. Note that many OBJ importers ignore vertex colors.
Binary PLY converts faster
Binary PLY is roughly 4x smaller than ASCII PLY and parses faster. Use binary when exporting from scanning tools.
Decimate dense meshes
PLY scan meshes can have 5M+ triangles. Decimate in MeshLab or Blender before converting to keep file size reasonable.
Check normals after conversion
PLY stores vertex normals; OBJ recomputes them on import. Verify lighting looks correct in your viewer.
Common issues when converting PLY to OBJ
OBJ imports without colors
Fix
Some OBJ importers ignore vertex colors. Blender, MeshLab, and 3D-Coat read them correctly; Maya, 3ds Max, and ZBrush often do not. If colors are critical, convert to GLB instead — vertex colors are reliably supported.
File is large
Fix
PLY scans typically have dense meshes. Decimate in MeshLab (Quadratic Edge Collapse) or Blender (Decimate modifier) before converting.
Model imports with flipped normals
Fix
PLY and OBJ use different conventions for normal computation. Run Blender's 'Recalculate Normals' (Shift+N) after import to fix lighting issues.
