If you ever wondered why the hell there are no options for the maya commandline renderer to modify antialiasing samples or other settings, you can do it yourself. The renderer options are set with a renderer description xml - file. This way you can modify this xml file and set all options you need. e.g I added the options for setting frame buffer pixel depth, samples and renderer type. They can be found in this section if you do a renderer -r mr -help command.
Extended Options: -buffer int Framebuffer type 2 = RGBA 8 bit bit 3 = RGBA 16 bit short 16 = RGBA 16 bit half float 5 = RGBA 32 bit float -minSamples int Scanline renderer min samples -maxSamples int Scanline renderer max samples -visSamples int Rasterizer visibility samples -shaSamples int Rasterizer shading samples -mblur int Motionblur 0 = off, 1 = no deformation, 2 = full
To use these settings simply download this xml rar file:
and replace the original in maya20xx/bin/rendererDesc. Then if you call your renderer, the options should work. As always it is no bad idea to save the original one.
