Fixing what ChatGPT did

I asked Chat to make me addon that would save selected objects as separate fbx files using last used fbx saving dialog options into a target folder i could set. Asked sometime earlier in other script to make the path in Windows format (other slashes) but seems Chat continued to use it as a rule .

It works when I paste the path in the input field but doesn’t work when I use folder button in the addon. Can somebody point where is the mistake or fix it please?

Here it is:

bl_info = {
“name”: “Export Selected as FBX”,
“blender”: (3, 0, 0),
“category”: “Object”,
“description”: “Export selected objects as separate FBX files using the last used settings”,
“author”: “Your Name”,
“version”: (1, 0, 0),
“location”: “View3D > N-panel > Export FBX”,
}

import bpy
import os

class ExportFBXSettings(bpy.types.PropertyGroup):
path: bpy.props.StringProperty(
name=“Export Path”,
subtype=‘DIR_PATH’
)

class ExportSelectedAsFBX(bpy.types.Operator):
“”“Export Selected Objects as FBX”“”
bl_idname = “export.selected_as_fbx”
bl_label = “Export Selected as FBX”

def execute(self, context):
    export_path = context.scene.export_fbx_settings.path
    
    if not os.path.exists(export_path):
        self.report({'ERROR'}, "Invalid path")
        return {'CANCELLED'}
    
    original_selection = context.selected_objects
    bpy.ops.object.select_all(action='DESELECT')
    
    for obj in original_selection:
        context.view_layer.objects.active = obj
        obj.select_set(True)
        export_path_full = os.path.join(export_path, f"{obj.name}.fbx")
        bpy.ops.export_scene.fbx(filepath=export_path_full, use_selection=True)
        obj.select_set(False)
    
    for obj in original_selection:
        obj.select_set(True)
    
    self.report({'INFO'}, "Export Completed")
    return {'FINISHED'}

class EXPORTFBX_PT_Panel(bpy.types.Panel):
bl_label = “Export Selected as FBX”
bl_idname = “EXPORTFBX_PT_panel”
bl_space_type = ‘VIEW_3D’
bl_region_type = ‘UI’
bl_category = ‘Export FBX’

def draw(self, context):
    layout = self.layout
    scene = context.scene
    layout.prop(scene.export_fbx_settings, "path")
    layout.operator(ExportSelectedAsFBX.bl_idname)

def register():
bpy.utils.register_class(ExportSelectedAsFBX)
bpy.utils.register_class(EXPORTFBX_PT_Panel)
bpy.utils.register_class(ExportFBXSettings)
bpy.types.Scene.export_fbx_settings = bpy.props.PointerProperty(type=ExportFBXSettings)

def unregister():
bpy.utils.unregister_class(ExportSelectedAsFBX)
bpy.utils.unregister_class(EXPORTFBX_PT_Panel)
bpy.utils.unregister_class(ExportFBXSettings)
del bpy.types.Scene.export_fbx_settings

if name == “main”:
register()

Hello. I suggest you ask chatGPT to use the pathlib module, it’s more os-agnostic. You can also try bpy.ops.export_scene.fbx(filepath=str(export_path_full), use_selection=True)

Thanks Gorgious. I’ll try for sure.

ps. It’s hard to keep ChatGPT focused although. It forgets what you asked before and now nothing works at all again :slight_smile: So perhaps I shoud be happy the addon worked with copy/paste the path .

Yes it’s not great at writing coherent long-winded addon code, but it’s great for small snippets to solve precise and particular problems.
