Request Tianwen Mars Mission

[N_Molson]

So 175 cm would be fine.

Found this model in the SimpleRockets2 mods site:

I don't think I can do such a detailed model (or I need more pictures), so tell me if I should continue...

 

[N_Molson]

More an hexagon than an octogon ?

 

[4throck]

Very nice model! Add some gold foil and solar panel textures, and it will look great!

Found some useful stuff :

 

[N_Molson]

Attitude control thrusters and antenna arm :

Tianwen's Orbiter Hi-res cameras and ground radar antenna :

Tianwen orbiting Mars :



A few shading issues to fix on the lander capsule but "nothing bad, nothing terrible, I've seen worse."

 

[N_Molson]

Does someone knows a tutorial in the context of Blender and Orbiter ? Because I'm going to need it... badly...

Playing around with D3D9 client advanced features ; right now I manage to have some bump-mapping and Mars reflecting on the probe shiny materials :

 

[4throck]

You might have some flipped normals there. To adjust materials you can use the D3D9 debug options.

Found some rover reference images.

An image of people testing the rover for scale:

Some dimensions:

I'm trying to write a .dll for the probe's orbiter.

From the French wikipedia article I have :

Wet mass : 3175 kg

Main thruster : 3 kN
Attitude thrusters : 8x120N + 12x25N

The 8x120N thrusters are obviously those of the "aft pods" (4x2), and on those pods we also have 8x25N thrusters. I can't find where are the last 4 thrusters, any clue ?

Any extra information (ISP, propellant mass) would also be very valuable.

4AM... but we have solar panels and antennas that deploy correctly !! Animation with hierarchy ! ?



Still the main antenna dish to animate.

@jarmonik: I'll consider some procedural bumps generation on the "hexagon" because even if the specularity issue can be fixed it won't look that great... What do you think ?

 

[4throck]

A normalmap for the gold foil will improve the gold foil.
But if you do it in 3D it would be even better. So yes, add those bumps and give it a more "rounded" appearance around the edges.

Looking really great !

(I don't have any extra info on the probe)

 

[N_Molson]

@4throck : I added a normal map but something doesn't work. Read the doc carefully and sent the files to jarmonik, we'll see...

I'll keep the current "hex mesh" as a "low-res" option, and will try some procedural bumps to simulate the "cover" look.

 

[4throck]

name_norm.dds should work...
Perhaps you are saving with an incorrect DDS format ?

 

[N_Molson]

Yes I'm using name_norm.dds on DTX1 512x512 .dds, I think the issue is elsewhere.

Having fun with procedural textures and displacement maps on Blender ; would be fantastic for generating asteroid meshes or even terrain. A bit tricky to use to simulate things such as MLI - and very time-consuming - but I'm learning, fascinating stuff.

 

[4throck]

I must get back to Blender someday

 

[N_Molson]

Yeah and with today's computers you can really do a lot of stuff, even in Orbiter/D3D9 ; it really takes more than a lot of triangles to get the FPS under 200 (with circa 2015 medium/high-end hardware)
