Gary are you wanting livery code based on the original multi part texture or what ?

@ Stu

Liv code based on what we have right now. Hopefully in the future we can have dedicated port / starboard tail and forward fuselage, and revisit and tweak it then.

@ Scott

Thanks dude! Way to go yet, but still tasty!

The splash screen sums it up very well! It reminds me of a Lightning T-shirt I used to have when I was a kid entitled Bat Out Of Hell!

How would changes to the elevators and wings affect the artwork?

Basically, it's got the wrong wings, they are F6 wings, T5 leading edge is straight. Also the elevator pivot axis is about 45 degrees out... not perpendicular to the body,

I don't know Blender well enough yet to have a go at fixing it, but wanted to float the points now to save re-doing work.

Cheers, Scott

way beyond my blender skills to edit that.

Can adapt artwork to accommodate any changes. Biggest of these is to establish separate imagemaps / mapping for the forward fuselage and the tail so that these are not mirrored.

Which begs the question - can we fix it (albeit temporarily) - by having an identical file to 1fusefront.jpg called 2fusefront.jpg, and edit the .ac to use that map for that side. Repeat with 1tail.jpg for the Vstab. 2 more textures, but I can keep file sizes manageable. Is that a viable fix (for now)?

Mirroring takes a shit on authenticity of the artwork - reversed decals and limited camo options are fugly.

Mhhh, if someone gave me the blender file and pictures that show what to change, I could have a go at it....

Hi Hans,

The tailplane / elevator axis of rotation of the real aircraft is aligned with the tail plane / elevator leading edge.

These images of the Cosford Lightning will help you see the pivot where it joins the airframe and the angle it's at. The curved slot is where the actuator in the airframe manouvers the tailplane around the axis of the pivot via a linkage.

In this image, you can clearly see two rows of screws that align with the pivot metalwork inside the elevator, that aligns with the pivot axis of rotation:

These wings are also of the correct shape for the T5 and earlier Mk's (straight leading edge, and alieron balance horn). The current wings of the FGUK T5 model are for the F6 (kinked and extended leading edge, no alieron horn).

Cheers, Scott

Hi Hans,

This diagram shows the pivot - it's actually slightly off the leading edge angle, but more that way than perpendicular.



Cheers, Scott.

OK, thanks Scott!!

Now on which original file should I work on?

- Do I use the .ac files from the official hangar ( www.fguk.eu/index.php/hangar/download/7-...h-electric-lightning ) and I have to import to Blender?
- Or is there already some original Blender file or some updated version somewhere where I do not have access to?

Cheers!

Algy I think was working on one newer than what's in the downloads area. As his cockpit screenshots show more instrumentation than what's in the downloadable version.

Although, the downloadable one may be the one with the updated liveries?

I did a quick import from the hangar version .ac file to Blender and the result was a bit frustrating. Like in the EC665 the mesh is a bit of a mess AND while the geometry of the tail is only a bit off, the geometry of the wings is quite far off.
So now the question is what to do.

  • Shall I try to get the mesh straightened out?
  • Should I correct the geometry of the wing? Since that change would be quite a big one, I am afraid that the livery is in danger of needing to be changed as well.
  • Should I correct the geometry of the tail?
  • I understand that at least the pivot for the tail should be adjusted.

    Hi Hans,

    I feel the most obvious improvement for this model would be the elevator pivot angle, for the biggest gain vs least knock-on work.

    What do you think?

    I'm going to start an airframe project tonight, beginning by gathering up as many known correct dimensions as possible, for beginning to take a modular approach to the Lightning airframe, as suggested in the other thread. Unfortunately as Stuart pointed out, this would result in pretty much starting a fresh with a new model.

    Cheers, Scott

    Mhhh, what is the point in improving the old model if it is already clear that you start a new one from scratch?

    If you need any help in modelling I would do what I can. I am not very good in modelling, but I am willing to try and learn....

    Hi Hans,

    That makes sense..

    I've probably way less blender experience, but want to learn.

    I've just completed the exercise of gathering up some measurements and general diagrams from air publications on the T4, T5, and F6.

    If you're interested, the files will be here for 1 week:

    wetransfer.com/downloads/bc41818d67e523b...0190116000036/ef0678

    Next thing for me is to list out the variations of the major parts and link them to which aircraft Mks shared them.

    Cheers, Scott

    Yeah, excellent :-)
    So you go ahead and I will continue with the Tiger.

    Oh btw, I am also just starting to learn.....
