Sample diagnostic messages

The following are some of the diagnostic messages Maya software rendering displays:

Motion blur and raytracing are both turned on. (Reflections, refractions and shadows are not motion blurred.)
You have motion blur turned on. Be aware that particles, lights and shadows do not motion blur. As well, motion blurred shadows may produce artifacts.
You have specified output to the Quantel format. In previous versions of Maya, this format only outputs to NTSC/PAL/HDTV resolutions, and does not output to fields. If the above restrictions are not met, rendering defaults to IFF image output.
You have specified output to the Cineon format. This format does not render out a mask channel.
You have specified a fractional animation by-frame step. This results in images over-writing each other for fractional frame counts. Please remember to turn on the modify-extension.
Near/far clipping values are too far apart. You may encounter numerical imprecision resulting in incorrect renders.
There are no renderable cameras in the scene.
