I tried to find posts about it cause i remember it was discussed previously but was unsuccesful. I know you have to render out as a sequence and have the frame # at the end. The only time i tried it it worked when i rendered in mental ray. Can someone please give me instructions on a succesful mapping of a movie node?
If your looking to make a animated texture, all you have to do is render out your animation in this naming convention:
myfile.0001.tga, myfile.0002.tga, myfile.0001.tga
it's important you have 4 digits or it wont work (for the frame padding). You can use any file format tho, .iff, .tga, .tiff, whatver.
then just check "use frame extension" in the file node, and there you go. by default, it will use the current frame as the frame extension. If you want to custom map this, you can right click on the frame extension and delete the expression. This lets you put your own expression in or keyframe it like you do anything else in maya.
