I have just recently had to reinstall maya on my computer. Before i had to reinstall it i had been doing batch rendering using the targa (.tga) format setting in Render globals. However now, after reinstalling it, whenever i try to use the targa format, my images from the batch render come out as (.iff) format, and have been made Microsoft Picture It! files. I have done this several times with the same problem, what is different this time?
