Question: Is multiple meshes per stage (similar to VesselBuilder) something that is intended to be implemented for Multistage2015?

 

[jacquesmomo]

Hello

as far as I remember, no, only one mesh for one stage....(or one stage = 1 mesh).


extract from the doc:
Meshname=abc (Name of the mesh) (Mandatory)


on the other hand you can put several "stages" at the same coordinates ..... ?

So can I add an AAPO lunar lander? The Saturn 5 is along the Z axis. While the LM is along the Y axis? Short of rotating the LM

I got an issue. I am sure the answer is easy. I have a new Vulcan. Where there is a main stage and 2 boosters. I have all 4 fueled up. But only the main stage is firing or at least visually firing? 4 tanks 2 booster and 1st and 2nd stage.

maybe the boosters need to be refueled

Scn after all 4 tanks filled. 4 tanks. 2 boosters 1st stage and 2ndstage.

From the scn only 1 thruster is using fuel.
I redid the ini and she works

A weird issue. I basically took the thrust from the main stage vulcan 4.9 KN. And have 2 others. So basically 3 main stages. But when I press P to launch the rocket in the HUD you see it add thrust and then goes to zero and add thrust again?

Maybe is the burn delay set for the getaway boosters (it was meant for upper boosters). Try to set it to 0 and see if the issue disappears

Thanks no. When I press P for launch the thrust applies to 4.9K and then goes back to zero and goes to 4.9

It is like it applys the thrust and re applys the thrust?

Can you do a video or a series of screenshots?

Here you go. So once I press P the countdown begins and it appls thrust and then applys thrust and the rocket lifts off
