So five meshes ?

1. TAA
2. ExAL
3. StnAL
4. ODS
5. MirODS

Here's the best photo I have managed to find that shows the additional TCS as well as the two cameras on the starboard side of the truss:

No, I just realized it wasn't needed. Please read the edit to my post.

Can't we just extend the external airlock with the necessary ODS/Mir DS components, and keep the baseline mostly constant?

There are issues with handrails and fabric covers.

We could just release a bare-bones Airlock for now, with the TAA.

There are issues with handrails and fabric covers.

What issues? Is it more than "Remove handrail group" and "add different cover group"?

How long do you estimate it will take to finish all? I'll need maybe 2 hours tops to finish the code: the TAA part is done, I'm now moving the ODS ExAL mesh code from Atlantis.cpp to their own existing files, thus loading the meshes only when needed (as opposed the current loading then always and then hide/show them).

The fabric covers need to be animated also.

I can do the five meshes in about 45 min.

The Mir extras, alittle longer.

Can't the Mir cameras and stuff be added to the ODS mesh, so we only need 4 meshes? We could hide/show those groups as needed. And the ODS textures you make the ISS version the default, and for Mir we change the texture in the code when needed.

 

[Urwumpe]

No big problem at all for us coders. You could add the covers to the hatch and make them a separate group. We animate the groups of the hatch including the cover. (Unless the cover is moved differently, then we just need two animations).

If there is no fabric cover, we remove it from rendering by changing its visibility flags.

 

[Donamy]

So how many meshes total ?

Can we do it with a single mesh for the external airlock + one optional mesh for the ODS?

 

[Donamy]

Should there be one mesh like the picture above ?

 

[Urwumpe]

Should there be one mesh like the picture above ?

Yes. We could replace the ODS mesh, should there be a different ODS for Mir.
Should there be no ODS, we just use MESHVIS_NEVER.

 

[Donamy]

Like this with the Mir stuff added to be removed by code. Or does the TAA need to be seperate, since it moves.

 

[GLS]

I think 4:
TAA
ExAL solo
ExAL for ODS
ODS (with one ISS texture and one Mir texture, and the extra Mir cameras and stuff in a separate group)

If both ExALs can co-exist in a single mesh, and by controlling what groups show, we could differentiate between the 2 versions, then one ExAL mesh is preferable.

The TAA should be a separate mesh as it could be added on the aft side of the ExAL (for STS-91 and 118 at least).

 

[Donamy]

Was the hatch used between the ExtAL and the TAA for 118 ?

Donamy: Could you make the ODS base black instead of grey? The grey APAS base only exists on the PMAs as the greying is caused by the exposure to the UV-radiation emitted by the sun. It has a bleaching effect on certain fabrics. The ODS isn't exposed to the radiation long enough for this bleaching effect to happen.

You mean the top EVA hatch? Then, no as no shuttled-based EVAs took place on STS-118. All the EVAs were based out of Quest airlock.

Probably, or otherwise they would have to depressurize the whole tunnel for an EVA.
EDIT: no wait, that I don't know. Probably there was a hatch between the TAA and the tunnel.

Regardless of what happens when they are docked, there must always be a way to go EVA from the shuttle.

No, not automatically.

The tunnel was already designed for earlier Spacelab missions, when the Shuttle was also routinely flying with the internal airlock.
