Hello Alexey,
I have got everthing to work! Thanks to your advices. I have another question. I've been trying to import a camera orientation file with the script (available in the attachments). I keep receiving the same error : Can't import cameras : path to the file. At first, I had a .txt file and then I wrote a Python Script to convert it into xml. It is still not working. Can I get more of your advices ?
Best regards,
Kal
