Watching a video on the landing. I heard them say it had 5 thrusters. 1 for landing. So I guess 4 thrusters for flight and 5th for landing. So 4 main and 1 hover.

So I may put the mesh put and if someone one wants to try to get it to fly have at it. Trying using VB.

AFAIR, its 4 throttlable engines used also for attitude control during propulsive phases. And one engine that is was added for orbit phase and for reducing the amount of dust impinging on the lander during final landing.

Thanks, I will add a 5th thruster to the mesh in Center and it had 8 thrusters for attitude.

But it isn't flying good for me so maybe someone can take a look using vb for help.

Here is the mesh and textures. https://drive.google.com/open?id=109x7H0EEOry6BJb0VcZ2_3o3SccbGkro
Hopefully someone can get it to fly right

I have been testing the Pragyan rover earlier this afternoon and It's working great and is visible!

Not sure. I guess it is just me doing it. I been working on the shuttle. But I posted the mesh for someone to try to get VB to get her to fly and land. Not sure if any has.

We should resume the development of the Chandrayaan-2 add-on to simulate both the partially successful Chandrayaan-2 and the planned Chandrayaan-3.

Chandrayaan-3 has landed on the Moon and there are no Vikram-Pragyan add-on. Although I'm no longer playing Orbiter since 2022 and have shifted to mobile games, I still like other users simulating real-life missions in Orbiter.

Not sure who "we" is. I was working on it but asked for help and got none. The rover part is easy. Just a mesh and some code to get it to move about.

Code:
const double y = 1.32;

const DWORD ntdvtx_geardown = 4;
TOUCHDOWNVTX tdvtx_geardown[ntdvtx_geardown] = {
    {_V(0, -y, (y + 1)), 1e6, 1e5, 1.6, 1},
    {_V(-(y + 1), -y, -(y + 1)), 1e6, 1e5, 3.0, 1},
    {_V((y + 1), -y, -(y + 1)), 1e6, 1e5, 3.0, 1},
    {_V(0, 1, 0), 1e8, 1e6, 3},
};

Is this the correct rover? I can update the mesh so the wheels can turn for steering

I wish we had more about the rover. I need to make more changes so the wheels can rotate 360 as they hit the arms.
Viramlander:VesselBuilder1\Viramlander STATUS Landed Moon POS 32.348126 -69.367621

Looking at this. It looks like another solar panel below the top one?
Also I wonder if this rover moved/trurned like a tank? No steerable wheels?

Ok.. I watched some video. It looks like the front and rear wheels are silver and the middle black.

It looks like for steering the 4 wheels rotate and the center doesn't turn
