I'm not at home, so I can't go through POV-Ray for the precise method, but
here's what I'd suggest:
1. Make a note of which specific piece in the DAT model you want to
emblazon with the rendered decal (let's say it's the 2x4 brick
3001.dat)
2. Convert the DAT model to POV using Lars Hassing's fantastic
L3P program (and join me in my daily moment of silence to
thank him for that fine resource.)
3. Open the output file in POV-Ray
4. Find the section of the file that starts "#declare 3001_dot_dat"
(this is where the 3001 brick is defined for the rendered output image)
Copy the entire definition of the 3001_dot_dat and insert it somewhere
else in the file
5. In the pasted section, change "3001_dot_dat" to "3001a_dot_dat" or
something similar
6. This is the tricky (time consuming) bit: go to the section of
the POV file in which the actual model is assembled from all the
declared part definitions, and find the particular statement that
defines the 3001 brick on which you want to put the decal
7. Change that statement from
object { 3001_dot_dat ...}
to
object { 3001a_dot_dat ...}
8. Go back to the section where 3001a_dot_dat is declared, and
insert the code to put the desired image on the brick. I can't
be more specific without having the software in front of me, alas
9. Do a test rendering with a small image size, and see if you got
it right.
10.If it didn't work, try again.
Okay, these aren't the most concise instructions, but I think they'll get the
job done. In any case, that's how I'd do it, or at least how I'd start on it.
To the many people out there more knowledgeable than I: Please correct my
instructions and amend them as you see fit!
Dave!
