Hi GLS, I'm not sure if this is intended but the end effector grapples the attach point the other way around as you can see here in my screenshot.
This is my custom mission for STS-31 using HST_ex for Hubble as I'm trying to understand the new cargo system (wich is great btw !)

I guess the rotation vector in HST attachment is 180º from what it needs to be... it should point "up" to the camera target.

Is this something I could edit in the CFG files ? For now it "works", I just have to remember that with the HST it's 180deg.

I have another question too. I'm fiddling with some ISS payloads from ISSR, I found a good PLID to position the payload, however it's lower and 90 degrees sideways, is there a way to change that ?

payload_attachment.png
A not-so-pretty diagram showing a section of the payload 90-inch radius envelope, the trunnion locations and where SSV expects the payload attachment to be (only one is needed of course). 99% of the payloads should place the attachment at the keel trunnion. Because bay 12 has the wing structure, the keel payload latch is a bit higher than on the other bays, thus the different location for the keel attachment if your payload is going there. There is no keel latch for bay 13.
Trunnion minimum and maximum lengths, and their diameters, are available in this document, but it is mostly a "cosmetic issue" and not a "functional issue".
The trunnions in the PFTA and in the DFI pallet could be used as templates for other payloads. Same applies for the scuff plates in the PFTA.

Looks like the attachment is at the center of the truss and not in the keel trunnion, and the rotation vector is 90º from where it should be. If the vessel defines the attachments in the cfg file, then adding the correct attachment parameters should be easy. You can leave the existing attachments for other addons and add new ones for SSV.

I'm guessing this is these parameters ? I'll edit the first line as it looks like it's the center of the mesh like in my screenshot above.
EDIT: changing these values or even remove all of them doesn't do anything looks like

Yes. The first line is the child attachment point. Even though it is P. The next values are position. I can open meshwizard and see where the attachment point is on the mesh.

My guess is
Code:
P     (longitudinal location of trunnion) 0 -2.412365     0 0 1     (+/-)1 0 0    BAY
and in the Mission Editor you indicate attachment 0

The attachment appears to be at the top of the trunnions. the center is .042 on the z position.

This is what I get when I load the S! into the sts2016 shuttle.

Can you tell me which vessel you are trying to add. Then I can tell you more what to change

Mh basically I'd like to have all payloads from ISSR working with SSV but that's a lot lol.
I was looking at how ShuttleFleet would've attach the payload and they have a "ShuttleBay" vessel that's attached on the Shuttle from ShuttleFleet, then on top of that the payload from in ISSR was attached on the ShuttleBay, wich can be found in "Config/Vessels/ISSR/STSBAY.cfg".

In their scenario it looks like this:
Like this:
Code:
STS-112:Shuttle
  STATUS Landed Earth
  POS -80.6208840 28.6271820 ;39B
  PRPLEVEL 0:1.000 1:1.000 2:1.000
  CONFIGURATION 0
  OV-104
  ISSV1
  <<Shuttle Stuff>>
  OMS ASSIST 134.00 89.000
  CALLOUT
  TGT_HEADING 42.440 228
END
ShuttleBay:ISSR\STSBAY
  STATUS Landed Earth
  ATTACHED 0:0,STS-112
  STS 112
END
S1:ISSR\S1
  ATTACHED 0:0,ShuttleBay
END

I tried to use STSBAY in Orbiter 2016 but that makes Orbiter CTD.

OK. So in SF and sts 2016 there is a limit of about 10 attachments. BUt if you attach a cargo bay vessel then you get more. But the name of the vessel you are are attaching is:S1:ISSR\S1?

Let me see what I can do. Can you post the scenario for SSV.

Release Tuesday is here!!!!! :hailprobe:
Space Shuttle Vessel 1.0 is finally out! https://github.com/GLS-SSV/SSV


Please, please, take a look at the manual before posting questions, as the info you seek might already be there. I think there is good help in there for the common user, as well as the developer who wants to put their payloads in SSV.


Thanks for all the support during these 2 years and 5 months of work, and as I did not make it all from scratch, thanks to all that worked on the foundations of Space Shuttle Vessel. :hailprobe:
Finally!

Yes I'm trying to directly attach S1:ISSR\S1 to SSV
Here's the files for my STS-112 mission

back up the cfg:

I did n't see and payload devices for the trunnions.

The Z value (2.7) adjust the height in the bay. X value will move it along the Zaxis

Superb, it works like I wanted ! Thanks a lot for your help and time, and explaination gattispilot !
I will try with another payloads next time, I also found in Orbiter.pdf the explaination for the attach points.

Boy, am I sure glad I spent all that time writing the coordinates for each PLID to put all the attachments in the correct places, so people could then just fly past all that. :cautious:

Could you detail the what each of the ILOAD entries does or point to a document that does? I'm having a hard time finding the parameter that controls whether or not a RTHU should be done. While on the subject of ILOADs, could entries for OMS-1 and OMS-2 be added? That would TRIM angles as well as PEG 4 targets and TIG. Normally only the OMS-2 TIG would be tweaked after MECO with a new one based on actual post-launch tracking data from the FDO. Targets were left as-is.

Normally only the OMS-2 TIG would be tweaked after MECO with a new one based on actual post-launch tracking data from the FDO. Targets were left as-is.
There is an file (I-LOAD List.xls) in the Doc folder with a list of the I-LOADs (which I just realized is incomplete) and their units and basic descriptions (for most of them).
The most changed parameters will eventually have a "pretty edit" capability in other tabs of the Mission Editor, so the user "doesn't get their hands dirty".

For the second stage roll angle there are 2 parameters (actually 3):
PHI_CMD​
rad​
commanded roll angle​
PHI_2STG​
rad​
desired roll command for second stage​
V_RHO_PHI​
fps​
switch velocity for roll command​
PHI_CMD is the initial 2nd stage roll angle, so 180º or PI radians. This should never change.
V_RHO_PHI is the relative velocity at which PHI_CMD is replaced with PHI_2STG.
So to roll heads up, PHI_2STG should be 0, and to stay heads down it should be 3.141593.


For OMS targets, the current implementation is nowhere near what it should be, so major developments in that area only after the ascent part gets reworked.

Ah nono, I do not touch the SSV attachment coordinates, it's only on the cargo that I try to edit to place the attach points in the good places so then I try to find the correct PLID for SSV.
It's just I don't know about modding in Orbiter so I first try with baby steps to understand the basics.
