change name based on background image name
I have a camera in max file with background image assigned to it. how can I change the name of the camera to the first 3 letter of the background image file name?
For example if the background image is here: "c:\temp\test34.jpg"
the camera name will be "tes"
I tried this in maxscript listener but got stuck.
bg = backgroundimagefilename
x = filterstring bg "\ "
x[size(x)] <== this line is not working
Thanks for any help.
