Please, help. I need to convert a lot of .smd files to fbx, I use this script in the console:

import bpy
import os

for root, dirs, files in os.walk('d:\Sourcemodels\smd'):
for name in files:
if name.endswith('smd'):
# delete everything
bpy.ops.object.select_all(action='SELECT')
bpy.ops.object.delete()
# adjust this to match the import smd operator
bpy.ops.import_scene.smd(filepath=os.path.join(root, name))
#Transform and save
k = 0.027 #scale constant
bpy.ops.transform.resize(value=(k,k,k))
bpy.ops.object.transform_apply(scale=True)
# export as fbx
bpy.ops.export_scene.fbx(filepath=os.path.join(root, name+'.fbx'))

but get this:


{'FINISHED'}
{'FINISHED'}
