Venus.ssc
the below code is out of date and just an example
Code:
   
 Replace "Venus" "Sol"
   {
     Texture "Venus.ctx"                     # use mine or your own map
     NormalMap "VenusNormal.ctx"             # use mine or your own map
     HazeColor [ 0.23 0.18 0.2 ]
     HazeDensity 0.15
     SpecularColor [ 0.13 0.12 0.12 ]
     SpecularPower 2.5
     Radius 6052
     
     Atmosphere
      {
       Height 60
       Lower [ 0.8 0.7 0.5 ]
       Upper [ 0.6 0.6 0.6 ]
       Sky [ 0.8 0.8 0.5 ]
       Mie              0.001
       MieAsymmetry    -0.2
       Rayleigh   [ 0.00001 0.0 0.0 ]
       Absorption [ 0.00025 0.0003 0.0004 ]
       MieScaleHeight 60.0
       CloudMap "venustype.png"                # this is my 100% synthetic cloudmap map
       CloudHeight 60
       CloudSpeed  90
     }     
     Timeline
     [
     # Before SPICE
     {
       BodyFrame { EquatorJ2000 { Center "Sol" } }
       Ending   "1550 02 27 00:00:00.000"  # add 2 months for orbit drawing       
       CustomOrbit "vsop87-venus"
       CustomRotation "iau-venus"
     }
     # SPICE
     {
       OrbitFrame { EclipticJ2000 { Center "Sol/Venus_bary" }}
       BodyFrame  { EclipticJ2000 { Center "Sol"            }}     
       Ending     "2649 11 25 00:00:00.000"  # less 3 month for orbit
       
       SpiceOrbit
       {
         Kernel  "de430.bsp"
         Target  "299"
         Origin  "2"
    Period   0.615
         BoundingRadius 1e10
       }   
      # CustomRotation "iau-venus"
    SpiceRotation
     {
       Kernel    [ "pck00010.tpc"  "naif0011.tls"  ]
       Frame     "IAU_VENUS" 
     }
     }   
     # After SPICE
     {
       BodyFrame { EquatorJ2000 { Center "Sol" } }     
       CustomOrbit "vsop87-venus"
       CustomRotation "iau-venus"
     }     
     ]   
   }


Basically the same as Mercury the rotation files are the same ,

of note is IAU_VENUS This is all Capitalized , that is the way it is in the rotation files
( If you want ,you can turn off the spice rotation for planets the default is so close that is hard to tell the difference other than a slight shift )

WARNING - for Linux and maybe Apple users ( Apple is an unknown at this time )
this file needs to be part of a single "SolarSystem.SPICE.ssc file
the c-Language read order is in affect on these Operating Systems

been trying out a new bit of code and running the old Venus texture through it
( the old one was a synthetically made image )
click on the thumbnail for a 2k preview
-- the first is the old map
Image Image Image Image

the second and third image is using 3 bands , the last is using 5 bands
