Ceres 32k (thank you Sirius_Alpha for the 32k idea, but I'm using a different texture):

I'm sorry, there is no texture, this is just the mesh.

Can I ask how do you unwrap the original model? My Blender can't finish Smart Unwrap, it takes forever.

i think i can do some improvements on that

it is just a random generated image that just happens to look good on the mesh
Nothing special about it

my improved version may look nicer on 67P mesh

Code: Select all

SurfaceObject "Perseverance" "Sol/Mars" {
   Class "surfacefeature"
   Mesh "Perseverancecmod.cmod"
   Radius 0.0027
    FixedPosition { Planetographic [ 77.4510 18.4446 0.0065 ] }
    FixedRotation {Inclination 90 AscendingNode 332}
   }
   
   SurfaceObject "Landing Spot" "Sol/Mars" {
   Class "surfacefeature"
   Mesh "Landing_site.cmod"
   Radius 10
    FixedPosition { Planetographic [ 77.38 18.4 0 ] }
    FixedRotation {Inclination 0 AscendingNode 332}
   }
   
   SurfaceObject "Landing Spot" "Sol/Mars" {
   Class "surfacefeature"
   Mesh "Mars-soil.cmod"
   Radius 0.1
    FixedPosition { Planetographic [ 77.4510 18.4446 0.005 ] }
    FixedRotation {Inclination 0 AscendingNode 332}
   }


You can do the rest...

i can't complete it without a model and textures
i can't make a perfect clone of the rover mesh and textures and the landing site textures...
i can make planetary meshes but not man made object meshes like rovers

Rover -> NASA mesh, you can download it. You can convert it with my tutorial (Method number 3). Use Anim8tor.

Texture -> use the highest resolution Opportunity image, so you can have a 8192x8192 pixels soil texture. Use the NASA map for the landing site.

Cmod landing site -> use Blender to create a square mesh. Export it as an obj file and convert it to cmod. Use the tutorial to add a texture to the mesh.

Perseverance - the scale of things. The yellowish texture in the background has a 256k resolution, which is clearly not enough even to see the details of the landing site.
