I wan't sure where to post this, but I chose Moray cos its something I can't
do within MOray (and not tried in POV-Ray).  I'm currently creating an
underground station scene and for the first time texturing everything (well
about 90%) and the majority with one image file - a mucky square, which is
being streched everywhere and using layers with various colour and opacity
to give definition.  Thats all fine until I wanted to keep it simple a box
with a tiled image-map (created seperately) and then having an opaque
'dirty' image over the top to give rough edges.

Basically therefore I would like two images over the top of each other, so
in Moray I created a material with two textures and after looking up in the
POVRay help file put filter all, 50% on the second layer.  Now varying on
what mood MegaPOV is in it'll either give me an error (if I preview - F9) or
just show the top layer image pure (no transparency).  Filter all seems to
be the answer (which I left on 0.5), but first of all can this be done - or
am I going to have to make a huge image with the tiled bits in to get this
effect.  Thanks for your time.
