You can also circumvent the raster3d step if you have ghostscript installed.
This is a postscript interpreter which can rasterize postscript in whatever
resolution you want.

To convert a postscript file into rgb with a resolution of 300 dpi, you
would issue a command like

gs -r300 -sDEVICE=rgb -sOutputFile=bla.rgb bla.ps

(Support for rgb output has to be compiled into ghostscript. You can use
 a different pixel format, however, and convert it into rgb later.)

I admit, however, that raster3d images look much more spiffy than molscript
images.
