Project LBS (Lunar Booster Stage) V1

[Grover]

after some searching, to no avail, ive decided to simply create what i was searching for, a booster stage that perform LEO insertion from an Energia HLV and then TLI, all the time carrying 40 tonnes of payload, in the form of the lovely CTV and LTV from francophone.

ive already got a simple mesh, and that works well in orbiter with another [simple] spacecraft3 config, next step: a textured and "orbinaut friendly" version, complete with documentation and one simple animation (opening the front of the inner payload [LTV] cone, ill give details of it later)

in the meantime, anyone that would be willing to texture this FROM SCRATCH (IE no UVs done) please let me know, i cant texture to save my life

right not, im starting the model again: im not happy with it at the moment, it needs to be redone and more details added (a single cylinder with an exaust isnt very aesthetic)

in terms of eprformance, it will be based on the Saturn IV-B, but with SLIGHTLY more oomph (to account for the 40-50 year time difference between them)

once ive got a new model, ill set you guys see it, and then hopefully ill be able to get a texture on it

thanks guys

Seems interesting, maybe you could try to compile a simple .dll module (modified Shuttle-PB ?) ?

 

[Grover]

maybe, but lets take it one step at a time, it needs a texture first, and then ill think about whether to make it spacecraft or custom dll

besides, id probably need some guidance if im gonna make a custom dll, coz im hopeless at the moment

ok, some screenies of the new model:

next, ill work on the UV map, maybe ill manage to get a mapping done at least, then ill test it as a spacecraft3 vessel and it hits OH

still, anyone that can do texturing for me would make my job MUCH easier

thanks guys

well, i managed to get a rough UV mapping together, but texturing it may be harder... anyone any good with photoshop?

 

[IronRain]

Why asking anyone else? This is a good way to learn it

 

[Grover]

coz im hopeless hard isnt the word, ive never done any CGI before

 

[IronRain]

There's a first time for everything

 

[Grover]

"except that which never happens"

i was hoping this was one of those things

 

[IronRain]

Get over it :lol: There are worse thing

 

[Grover]

well, this is going to be a poor texture... i think ill go for a scheme similar to the CTV

Convert your model in 3ds or obj format ,draw a simple texture for only part.

I converting in mesh format the missile and dds format the texture,and mapping the model

 

[Grover]

forgive me, but i dont fully understand your english, what are you trying to say?

well, so far so good, i have a model done, the one animation is sorted and the engine stats are just about good, now im just missing a texture.

i need the following things:
a tutorial for making a good texture
somebody tot ell me how to apply the texture to the orbiter render of the vessel, how do i tell orbiter to put the texture onto it?

Sorry for my bad english

I can do this:

so if i give you the model, you will texture it for me? in that case, here is a zip containing the model (3DS) and a BMP UV template of the UV mapping i did, feel free to change the mapping, but send me the new model back if you do.

i want to style it similarly to the [ame=http://orbithangar.com/searchid.php?ID=3918]ESA CTV[/ame], as this is the vessel it will be carrying.

dont change the model other than the UV mapping, its all scaled perfectly

thanks for the help!

 

[marcogavazzeni]

I'll have to divide the texture in two ways
cylindrical and planar

 

[Grover]

thats what i did, as you can see with the texture map i made.

sorry, i should have labeled each component, so:
lower left rectangle is the outer shell
upper left square is the inner payload area
upper circle is a planar map of the rear od the stage (including the cone section)
lower circle is the bottom of the payload bay
upper right shape is a cylindrical mapping of EVERY RCS tank on the rear, with uvs packed on top of each other
right-hand rectangle is a cylindrical of the exhaust

of course, if you do your own mapping, just ignore that and do your thing, remember, ill need the UV'ed model once you're done

thanks man!

alright, its a little buggy, but it works! ill include a scenario with the LTV and CTV attached with UCD (ive named myself and Gavazzeni as the crew of the CTV, along with M_Schweiger ), once I have the textures, and have worked out how to get them onto the mesh it can hit OH! then ill start to make a V1.1 where i'll fix some bugs in the mesh that ive only just noticed and work on the spacecraft 3 module again, improving it a little more

in terms of performance, its basically a slightly bigger S-IV-B, same Isp, similar weights but a little more fuel, it can reach TLI velocities with 1000M/s Dv left over, it could potentialy do the LOI itself, reducing load on the CTV's fuel

as soon as Gavazzeni gives me the textures, you'll be free to download it, i should be able to do the v1.1 myself, just adding another shape or two onto the UV map and layering them onto the existing texture.

thanks for the help guys, you've been great

You seem to have misunderstood, i have already mapped the model, i just need it to be textured, prefferably in a single dds file.

I have fixed an error in the model, and should have proper internet back soon, then we can try again

Thanks for the help anyway
Grover

PS mobile internet is rubbish

 

[Grover]

ok, ive got access to the internet (sort of, im at my grandparents, so i dont have access to orbiteror my project folder), but i have good news!

first, ive fixed the error in the mesh, now its just awaiting a texture (read further down)

secondly, ive decided to re do the engines a little, since it will be towing a CTV-LTV, i decided to set the engines up with a similar ISP (8Km/s, almost twice that of the original S-IV-B) and adjusted masses to keep the delta-V at around 3.5Km/s for the full stack (after orbit insertion)

but im left with two problems:
first, it still has no texture, if somebody could help me with this (just a simple texture for now) please let me know and ill get the model to you to texture

finally, the RCS are way off, since the default thruster is set close to the CoG, it takes a huge amount of thrust to get the thing rotating, which then makes the LIN thrusters way too powerful, it there any way i can change the Spacecraft3 parameters to reduce the thrust needed for adequate torque? at the moment, the RCS are almost as powerful as the mains

thanks to anyone that can help!

It's nominal that a space tug has a minimal RCS system, it should be weak. Just define the RCS thrusters farther away from the COG (to be realistic, draw them on your mesh, and enter the Vector3 coordinates).

How do i define the coordinates for the thrusters? Then i wouldnt need as much thrust and the LIN thrusters wont be too powerful

Thanks
