export obj to relative file path script:

import bpy
import os

blend_file_path = bpy.data.filepath
directory = os.path.dirname(blend_file_path)
target_file = os.path.join(directory, 'myfile.obj')

bpy.ops.export_scene.obj(filepath=target_file)

further export obj options:

bpy.ops.export_scene.obj(filepath="", check_existing=True, axis_forward='-Z', axis_up='Y', filter_glob="*.obj;*.mtl", use_selection=False, use_animation=False, use_mesh_modifiers=True, use_edges=True, use_smooth_groups=False, use_smooth_groups_bitflags=False, use_normals=True, use_uvs=True, use_materials=True, use_triangles=False, use_nurbs=False, use_vertex_groups=False, use_blen_objects=True, group_by_object=False, group_by_material=False, keep_vertex_order=False, global_scale=1, path_mode='AUTO')

  • $\begingroup$ Hi, thank you it works. And how can i export it in a relative subfolder and an absolute path? $\endgroup$ – Danyl Bekhoucha Jul 20 '17 at 22:22

    $\begingroup$ he script i gave you exports to the folder of the .blend file if you want to ad a subfolder you can just add it in this line: target_file = os.path.join(directory, 'subfolder', 'myfile.obj') An absolute path you can provide as a string bpy.ops.export_scene.obj(filepath="C:/path/to/file.obj") $\endgroup$ – Madlaina Kalunder Jul 21 '17 at 8:23
  • $\begingroup$ I don't undertand which line i should replace. I want the user to type the absolute or relative path in the same place, then after the path it adds 'lod0_' then it takes the mesh's + name name = 'game_asset' and add + '.obj'. $\endgroup$ – Danyl Bekhoucha Jul 22 '17 at 12:02
