[The Shadow]

i guess this is good enough. heres the new booster textures, but the mainbody will have to be updated in the second release

also included is the new mainbody as far as i have it, in case you feel like playing with it, but it looks bad

 

[The Shadow]

i have succesfully revamped the whole mesh, so now it is multistaged, and has more capability than before. now i'm going to work on retexturing this monster and implementing the new multistage capability.

i also added a payload for the nose fairing. a massive lander for colonization or scientific purposes.

what would be the best way to work out the stages in Multistage2 and Spacecraft3?

the way the rocket would run is the 4 boosters and the main booster would get it to orbit, the 4 boosters and 4 external tanks for the main booster engine would then jettison once in orbit. then the main booster engine would push it out of Earths SOI and towards the target planet(Mars for example) and then it would jettison. then the orbiter and payload would reach the target, the orbiter's engines would slow it down for MOI then the payload would jettison, the payload is a lander for ground OPs and colonization. once the payload enters Mars atmospere the 4 fairings which have been protecting the lander from scarring and microsats will then jettison.

my question is this: since the orbiter and lander are both SC3 craft how do i have the lander and fairings come after the orbiter in the stack?

and also since i have no prior knowledge of Multistage2, how do you make 4 instances of an object on the same stage? i looked at a few tutorials but couldn't find anything.

 

[MJR]

All you need to do is press J for stage separation. If you press F the fairings will jettison. Just forget about F until you need it. When you say four objects on one stage, do you mean four payloads?

 

[The Shadow]

no, more like the 4 SRBs, how do you have them all as one stage?

and what i meant earlier was how would i phrase it in the .ini file? would the fairings and lander be a separate stage and the orbiter be a payload? how would that work out in the most efficient way? i'm trying to make the lander and fairings separate from the lander and then enter the atmosphere.

great to be working with you again btw, thanks

UPDATE:

i have completed the orbiting section as a SC3 craft, it now has engines and working animation.

unfortunatly i still don't quite know how i'm going to keep the lander attached and still keep the orbiter as a separate stage. becuase i want to be able to do the animations while transfering to the target planet, it's no use having this massive artificial G section if your not going to use it while on the many month journey to the new planet.

I'll answer the first post. When you are in the 3D anim8or program you need to name the booster like this. SRB_1 and etc. Under the booster configuration in the multistage ini., you define it as N=4 so it shows the four boosters. Do not move the meshes any way. Line them up as you would like them in the 3D program right next to the main ship and export ithe boosters as its own mesh.

The farings also have their own configuration. Here is an example.

[FAIRING]
N=2
MeshName="multistage\able_cap"
size=2.85
Diameter=4.55
Height=8
angle=0.
off=(0,0,-1.5)

Place it right before the payload though.

 

[ar81]

Sounds like your normals are reversed. The normal indicates the "face" of a poly, and single sided poly's are only visible on one side. In essence, your mesh is "inside-out".

Perhaps Anim8tor or MeshWizard has a tool to reverse the normals for you, I haven't use either.

Mesh Wizard can flip visible side for selected groups. If you need to flip triangles, you may need to find another tool.

To flip a triangle, you need to flip the numbers in the mesh.
For example we have triangle

0 1 2

to flip it we write

2 1 0

 

[The Shadow]

so i should have a "multistage" folder in "Meshes" that contains my meshes. and there should be 4 exactly the same but named like

"Galaxy_SRB_1"
"Galaxy_SRB_2"
"Galaxy_SRB_3"
etc?

i borrowed very heavily from Liber's earlier multistage version, thanks Liber!

That looks exactly like it should. You might have problem with the [BOOSTER_X] sections because it is way different than the stages.

 

[The Shadow]

i'm just trying to get it to work now; placement, engine power, etc. will come later

---------- Post added at 11:25 PM ---------- Previous post was at 10:51 PM ----------

i did a test and here is what happened.

SRBs fired and jettisoned correctly
ETs jettisoned correctly
main booster jettisoned, but it was flipping end over end, i would rather it go straight back.
interstage did not jettison as required
orbiter did not jettison as a payload until fairings jettisoned
lander was attatched to interstage.

nothing after the main booster was correct. any ideas on how i should fix this?

 

[MJR]

Fairings are for getting out of the atmosphere. In the scenario file, make sure you define interstage as 1.

 

[The Shadow]

in this case the fairings are for getting into the atmosphere.


interstage was already defined as 1, but i did not call it an interstage, i called it a stage and made it extremely small power in the .ini file.

[INTERSTAGE_1]

put that in?

 

[MJR]

An interstage should look like this.

[STAGE_1]
Height=39.4
Diameter=6.6
EmptyMass=13000
FuelMass=210000
Thrust=4323600
BurnTime=130

eng_1=(-0.653,0,-11.5)
eng_2=(0.653,0,-11.5)
eng_diameter=0.8
ENG_TEX=Exhaust2
ENG_PSTREAM1=stages
ENG_PSTREAM2=Contrail4
ATT_PSTREAM1=Contrail1

[SEPARATION_12]
MeshName="multistage\gem_interstage"
SEPARATION_DELAY=0
Diameter=0
Height=0
EmptyMass=0
off=(0,0,12.5)

[STAGE_2]
IGNITE_DELAY=2.5
Height=36.02
Diameter=9.8
EmptyMass=3600
FuelMass=54500
Thrust=1130000
BurnTime=335
off=(0,0,14)
MeshName="multistage\Titan23Gstg2"
eng_1=(0,0,-4.95)
eng_diameter=0.6
ENG_TEX=Exhaust2


You see how it falls in place in the ini? Also, show me the scenario file real quick too. Post the code here.

[MJR]

The scenario fie is good. Now just follow my instructions on the post before yours for the interstages.

 

[The Shadow]

done. i did a test and i loose the interstage completely. i have been playing around trying to get it to work, i think i messed it up.

 

[MJR]

Show me what you have now in the ini.

 

[The Shadow]

well, a final tweek has it working now. booster and interstage sep. works.

now i'm going to see if i can fix a few minor issues, work on placement of the stages, and other settings. i THINK i can handle it from here. thanks for the help

 

[MJR]

No problem. If you need anymore help just ask.
