This is the .3ds file so far.

Hi. Try this mesh.

 

[Dambuster]

Thanks, but that didn't work. I'm going to download a different programme and see if I can fix it from there (I suspect that texture problems may be causing this...)

UPDATE: I've gotten the mesh into Orbiter successfully and scaled as well. Animations and flight dynamics etc etc will come next/later.

Hi. Try this mesh.

Nice conversion...but I think is little to big...?!
And to dark too.

Nice looking ship.

Seems to be about 10 times larger as it should be.

Yes, it was. I'll upload an updated mesh later tonight probably. I've managed to work out the animations on the ailerons, and next I'll probably try to work on the elevators/cockpit 'hatch'.

Also, I'm at a dilemma: should I keep the vessel size larger (I'm using spacecraft3) and have it display reentry flames properly (but then it doesn't display the cockpit correctly), or should I make it far smaller, to the point where the reentry flames barely show up, but the cockpit works? Even better, does anyone know of any ways of getting around this?

You have a misconception there:

The size parameter of orbiter vessels does not scale the mesh, but instead tells orbiter, how large the spacecraft is - the mesh is only a visual representation.

You could make a 800m spacecraft and a 40m size, making the reentry flames appear inside the mesh... etc.

I understand what you're saying (and I think I phrased my previous post badly), but if I did have a 800m mesh and a 40m size, when I looked at the mesh from inside the spacecraft, would I only see 40m of it around me?

Usually geting info on ship size,COG,cross section with Shipedit,it could be found in orbitersdk,utils folder.Maybe there's are other way...but this is fine for me...
Most likely if you change size you need to again get a rotation point for animation...

Usually, you should see nothing of the spacecraft from inside. But that is another topic.

Orbiter only renders a mesh in internal view, if it is flagged like that. For example as VC mesh.

 

[Dambuster]

liber, thank you! I had no idea that existed

So...how would I best go about making a VC mesh?

EDIT: I just realised how INSANELY cool a VC could be for this ship

I'm not familiar with this ship whatsoever. I just converted it to msh for Dambuster so he could see if it worked.

 

[tgep]

I would go with the correct vehicle size and then write a file for the Re-Entry effects plugin. I've done it several times and it works like a charm. You'll already be looking at the mesh in OMW or similar program so you'll have an easy time getting the locations on the mesh. That will solve any problems with re-entry effects not sizing properly.

 

[Dambuster]

Well it's coming along nicely so far, but I'm having troubles with the aerodynamic values in spacecraft3. I seem to be unable to get the nose up whilst trying to land at KSC. Any tips?

Add trim into configuration file and trim craft during landing...

TRIM=0.05

Key Insert and Delete

You will see it at left corner where are other info.

 

[Dambuster]

Sorry, I wasn't clear in what I said. I meant to say that as soon as I start a scenario which has me placed on a near-final approach into KSC, my velocity vector begins to sink. Whilst I can raise the nose to an extent, this appears to have no effect on the 'movement' of the velocity vector, and I can only ever keep the nose pointed ~10 degrees above the vector indicator.

If someone who knows more about this than I could please read this briefly, and see if there are any glaring errors which might be causing what I described above, I'd be really grateful:

Size parameter is far too small. Size is about half the length of the vessel, or another dimension which is useful for describing it.

 

[Dambuster]

Ok thanks, I've just fixed that, but it isn't flying any better.

P.S. I know my values for the engine and retro rocket thrusts are TOTALLY whacked, but I did that just for laughs. I'll change it back later.

 

[tgep]

I'm pretty lazy when it comes to figuring out aerodynamics so nine times out of ten I use this:

[AERODYNAMICS]​

• newMODEL : possible values are “shuttle”, “dglider” or “capsule”.

and use dglider for small vessels under 30m long. For the bigger stuff I use Shuttle.

 

[cinder1992]

I wouldent use the shuttle if I were you, tgep. the real shuttle is a flying brick and the default one is A FLYING TWO-STORY HOUSE Aerodynamic-wise...
