Make Maya render batch files easily...
Render Bender is a launcher for Maya's RENDER.EXE program. It provides you with a convenient interface for generating multiple batch renders with Maya's built in RENDER.EXE program. You can access any of RENDER.EXE's flag options, make and save flag lists, copy flags from one render to another and set up sounds to play in between renders. It also performs limited syntax checking on your input to help avoid costly mistakes. However, it is only recommended for experienced Maya users and it won't make your modelling any better.
I have included some visual instructions to make it easier to use.
