Movie texture, problems getting it to play.
I'm having trouble gettting a movie file to play when it is mapped onto a plane surface. The tutorials I have found say to click 'Use Frame extension' but I don't seem to have that option availlable.
I am actually trying to project a movie through a spotlight like a gobo/silhouette onto a surface following a tutorial on digital-tutors.com but I can't get this to work either. I have been using a targa sequence with an alpha channel, perhaps the problem is in the file types I'm using? When I check the 'Use Image Sequence' box the frame number goes up accordingly when I scrub along the timeline but the animation still sticks on the first frame. I have done a test render to see if it is the preview but all the frames have the same image from the animation.
Sorry if this doesn't make much sense! If anyone has a basic explanation of how to do this I would be really greatful as it's proving frustrating at the moment.
Cheers very much
