Space Shuttle Ultra 1.25 Revision B development

[DaveS]

A shot of the OMS mapped.

Nice, how about an slight overhead shot? Does the AFRSI extend over onto the tiled forward section? Also, does it use it's own texture file? This way we can get higher and more detailed resolution on the actual texture.

 

[Donamy]

No, It still uses the one texture. A dedicated texture would slow loading.

 

[DaveS]

Hardly. The VC alone uses 48 separate high resolution textures. For me it blazes through them in micro-seconds, the loading of planetary and base textures takes longer!

Hardly. The VC alone uses 48 separate high resolution textures. For me it blazes through them in micro-seconds, the loading of planetary and base textures takes longer!

And the VC textures aren't really effective, since many of the textures have a much higher resolution as we really needed for the task.

 

[DaveS]

Good news: I managed to find some photos of the elevon coves and they're being added right now. Once those have been done, the wings are flight-ready including the elevons/seal panels.

Oh, if someone goes to see Atlantis, I think somewhere in there is a big color diagram of the SSME, with ALL the pipes and stuff. Please take a good picture (or 50 :lol of that, as the couple of pics I've seen on the interwebs aren't good/close enough. Thanks!

There are several schematic diagrams of the SSME on the web (I like the one with the "POGO preventer"). Is that what you need?

Or, will this help?

And the wings are done and flight ready. The only left for me is work inside the PLB (adding the aft PLBD bulkhead latch rollers and EVA handrails) and then adding the midbody vent doors.

 

[Donamy]

The RCC and wing roots look great !.

Thanks, but this is what I'm looking for:

but a lot bigger and in color (I have one in B&W but can't tell enough from there). Thanks anyway!

Oh, I almost forgot: can anyone get me the coordinates for the LH2 backup dump port* and the LH2 fill & drain port? Thanks!

*the little "dot" immediately above the wing and below the access door

 

[DaveS]

Oh, I almost forgot: can anyone get me the coordinates for the LH2 backup dump port* and the LH2 fill & drain port? Thanks!

On the current mesh? In that case, the coordinates are as follows:
Backup dump port: -2.85, -1.16, -7.30
LH2 F/D: -3.18, 0.71, -10.51

Donamy: When you make your cuts on meshes in AC3D, how do you do it? Do you use the Boolean tool or some other method? For some reason, the Boolean tools always fails on me in some form, be it a CTD or just tearing the mesh apart completely.

 

[Donamy]

Try to make your cuts within as few faces as possible, this way you avoid unwanted distortions. Also, copy and paste just those faces needed, as a new mesh, and make your cuts in that. then it is just a simple case of re-attatching those faces to the original model.

 

[DaveS]

The midbody AVS vent doors have now been added. The only midbody work left now is the EVA handrails on both bulkheads and the aft PLBD bulkhead latch rollers.

I'm not getting anywhere with the new EVA handrails. Donamy, do you think you could give them a shot?

Here's the link to a folder which contains the best photos I have managed to find: Orbiter PLB bulkhead EVA handrails

Are you sure its at the Atlantis exhibit? I cant recall seeing anything like that at all. I think I should have noticed it if it was that big...

New orbiter with the midbody and aft compartment vents:

Nope, too trivial for me.

OK. How's everything else coming along? Only things left are the PLBDs/radiator panels and the texture improvements.

Donamy: I got the textured OMS pod. Could you see what you can do to improve my mapping and the rest of the textures to actually match up with the new mesh?

Link: Complete_OMS_pod.zip. It is using a new dedicated texture file with upscaled textures.

So, I'm tying to make the MPS vents, and because it was not working (keep reading), I moved it to the Atlantis class to make it similar to the way the SSMEs are handled. But it still doesn't work! :facepalm: At T0 the stack just flips and heads on to another galaxy (think it's because SRB ignition). If I don't create the vents it works fine... I'm creating the vents next the SSMEs so the timing of creation shouldn't be a problem... Is there a limit to the number of thrusters or something?

 

[Urwumpe]

Is there a limit to the number of thrusters or something?

No. But how did you define them?
