# x3d import in python

I have a huge amount of .wrl files. They mostly contain a single mesh. I want to write a small python script that loads each of these files, then reduces the contained meshes and saves it to a new file (ideally again a .wrl, but not necessary)

My script so far

import bpy
import os

for i in os.listdir("C:/PathToFiles"):
if i.endswith("n.wrl"):
fullPath = "C:/PathToFiles/" + i

bpy.ops.import_scene.x3d(filepath=fullPath)

bpy.ops.object.select_all(action='SELECT')
bpy.ops.object.delete()

continue
else:
continue


The saving part is missing for now. When first trying this I got the error message "blendata not defined" in line 2223 of import_x3d.py. I corrected this by replacing all occurences of blendata with bpydata.

Now it crashes with error in line 2044 of import_x3d.py with

ValueError: matrix * vector: len(matrix.col) and len(vector) must be the same

Since I have no real insight into the script or the .wrl file format I am kinda lost. Any suggestions?

tmp = texmtx * luv.uv.to_4d()
