with the craft waking up and the minor moon meshes done

time for this

I am using a edited version of Jestr's " new_horizons_jpg_v2.zip "
http://celestiamotherlode.net/catalog/s ... don_id=913

just the cmod and some editing ( the cmod calls ALL CAP image names and file extensions )
added a new gold foil and a normalmap for the foil

still working on it

The spice data
for now it is ONLY location data.There is a NASTY problem with the rotation bc files.
they are NOT continuous and will require a new timeline entry for EACH
the 2014 file "merged_nhpc_2014_v000.bc" has 4 different segments in it
Code:
ckbrief -rel -g merged_nhpc_2014_v000.bc naif0010.tls new_horizons_0664.tsc
 
CKBRIEF -- Version 6.1.0, June 27, 2014 -- Toolkit Version N0065

you will need the bsp "nh_pred_od077.bsp"
ftp://naif.jpl.nasa.gov/pub/naif/pds/da ... /data/spk/

the Pluto/Charon spice add on is fine to define the location of the barycenter used

and this bsp file ALSO!!! has different time segments REQUIRING using a timeline
( as you can see this is going to be VERY complex to add the rotational data in )
Code:
brief -c nh_pred_od077.bsp
