I have an aircraft mesh with two square meshgroups located in XY plane. I would like to use them as displays for two default MFDs in virtual 3D cockpit, that will be synchronized with two ones in generic glass cockpit. There are two vessel examples based on Lua with MFDs in VC, namely Delta-glider and Atlantis. There are far fewer Lua scripts for Atlantis, so I thought it will be easier to take it as an example. It looks like the main "Atlantis.lua" script contains all code for MFDs implementations, maybe the following piece, but I am not sure:
C++: 
----------------------------------------------------------------
-- Respond to MFD mode change
----------------------------------------------------------------
function clbk_MFDmode(mfd, mode)
    oapi.VC_trigger_redrawarea(-1, AID_CDR1_BUTTONS + mfd - MFDID.LEFT)
end

----------------------------------------------------------------
-- Load generic glass cockpit mode
----------------------------------------------------------------
function clbk_loadgenericcockpit()
    vi:set_cameraoffset(_V(-0.67, 2.55, 14.4))
    vi:set_cameradefaultdirection(_V(0, 0, 1))
    return true
end

So, maybe anyone could help me somehow to implement two default MFDs for my mesh (two square meshgroups for MFD displays)? I hope this will be a good example for future vessels based on Lua.
 
I'm afraid I can't figure this out myself. There may be a lot of misunderstandings. I'm trying to add the only left default MFD into my VC (maybe the right MFD should exist too). I'm not sure if I should assign a texture for my MFD rectangle meshgroup. Atlantis example has many features like MFD brightess and so on, I really need the simplest example. Probably, it would be much easier to implement MFDs using the VesselBuilder, but I'd like to do it on Lua... So, if anyone has dealt with MFD (not necessarily on Lua), then I will be very grateful for any help.

Do you know where that flag can be seen? It's not presented in a mesh file.

I experimented with Atlantis.lua script and noticed that the following code is enough for displaying the left and right default MFDs in VC:
C++: 
function clbk_loadVC(id)
    local mfds =
    {             
        pos = _R(0,0,0,0),
        nmesh = mesh_vc,
        ngroup = 0,                 
        flag = 1,
        nbt1 = 6,
        nbt2 = 6,
        bt_yofs = 1024/6,
        bt_ydist = 1024/7
    }
    local mfdgrp = {33,34}
    


    if id == 0
        vi:set_cameraoffset(_V(-0.67,2.55,14.4))
        oapi.VC_set_neighbours(-1, 1, -1, -1)
    elseif id == 1
        vi:set_cameraoffset(_V(0.67,2.55,14.4))
        oapi.VC_set_neighbours(0, -1, -1, -1)
    end
        
    for i=0, 1 do
        mfds.ngroup = mfdgrp[i + 1]
        oapi.register_mfd(MFDID.LEFT + i, mfds)
    end
    
    return true
end
I changed some parameters here and I commented the rest of code between line 1752 and line 2182. The MFDs in Atlantis VC are displayed correctly and they are synchronized with MFDs in glass cockpit (MFD buttons are not interactive yet (I commented it)).

So, I'm using the following part of Lua code for my plane:
C++: 
function clbk_loadVC(id)
    local mfds =
    {
        pos = _R(0,0,0,0),
        nmesh = 0,
        ngroup = 0,
        flag = 1,
        nbt1 = 6,
        nbt2 = 6,
        bt_yofs = 1024/6,
        bt_ydist = 1024/7
    }
    local mfdgrp = {17,18}

      if id == 0 then
           vi:set_cameraoffset({x=-0.49644,y=0.60708,z=1})
           oapi.VC_set_neighbours(-1, 1, -1, 2)
        elseif id == 1 then
           vi:set_cameraoffset({x=0.49644,y=0.60708,z=1})
           oapi.VC_set_neighbours(0, -1, -1, 2)
        elseif id == 2 then
           vi:set_cameraoffset({x=0,y=0.45,z=-1})
           oapi.VC_set_neighbours(-1, -1, 0, -1)
      end

    for i=0, 1 do
        mfds.ngroup = mfdgrp[i + 1]
        oapi.register_mfd(MFDID.LEFT + i, mfds)
    end
    
    return true
end
A have two square planes in my mesh for two test MFDs, but they don't show anything:

Без імені.png

These two square planes don't use a texture and have the material properties in the mesh file the same like for the Atlantis one.

Any suggestions for the issue detection and any help help are very welcome 🙏
 
Your mesh is defined as 0, is it OK?
BTW, you can use the meshc tool to generate a Lua table for your mesh group names

Click to expand...
I suppose yes, since "nmesh" is the mesh index, and I have the only one mesh, so I am using "0" for it. Maybe I should define the mesh for MFD additionally, I don't know. I can post the whole script (I am using a single script) if it could help?
 
I just ported the vessel so I'm not exactly 100% sure of what everything does but do you set the visibility mode of your mesh? cf vi:set_mesh_visibility_mode :
Code: 
function load_meshes()
    -- Retrieve mesh handles
    hOrbiterMesh        = oapi.load_meshglobal("Atlantis/Atlantis")
    hOrbiterCockpitMesh = oapi.load_meshglobal("Atlantis/AtlantisCockpit")
    hOrbiterVCMesh      = oapi.load_meshglobal("Atlantis/AtlantisVC")
    
    -- Load meshes
    mesh_cockpit = vi:add_mesh(hOrbiterCockpitMesh)
    vi:set_mesh_visibility_mode(mesh_cockpit, MESHVIS.EXTERNAL)

    mesh_orbiter = vi:add_mesh(hOrbiterMesh)
    vi:set_mesh_visibility_mode(mesh_orbiter,  bit.bor(MESHVIS.EXTERNAL, MESHVIS.VC, MESHVIS.EXTPASS))

    mesh_vc = vi:add_mesh(hOrbiterVCMesh)
    vi:set_mesh_visibility_mode(mesh_vc, MESHVIS.VC)

    -- Optional meshes
    mesh_cargo      = nil
    mesh_platform   = nil

    -- Visual handle
    vis             = nil
end
 
Sorry! WRONG information. It's the textures that need flagging with a "D" and only for instruments that need updating (had to check the last MFD that I made).
The meshgrp is a simple square with UVs no tex. and a black material.

I thought about it, too. It's something strange I don't understand. The AtlantisVC.msh file contains "CDR1" meshgroup for the left MFD. A texture isn't assigned for this meshgroup (it's "0"):
Code: 
LABEL CDR1

But it has vertex texture coordinates, namely UV coordinates, I suppose (7 and 8 columns above). Are UV coordinates needed if a texture for a meshgroup isn't used? (I tried to add the UV coordinates into the mesh file like for Atlantis, but it didn't help).

No problem, I hope we can understand it. I'm using:
Code: 
vi:add_mesh('Cirrus-SR22/Cirrus-SR22')
vi:set_mesh_visibility_mode(0,bit.bor(MESHVIS.EXTERNAL,MESHVIS.VC))
I attach full code below. But I don't use oapi.load_meshglobal(). Could it be the reason?

Your meshgroup has the flag "1". Does it mean "D" (dynamic) flag?

The same question. Are UV coordinates needed even if a texture doesn't used (set to "0")? Here's my left MFD meshgroup (I added the UV coordinates into the mesh file like for Atlantis, but it didn't help):

Yes, you need UV coordinates for an MFD.
Give your MFD group a UV mapped texture, but in the mesh don't use the texture, label it 0.

Code: 
MATERIAL 14
TEXTURE 0
LABEL lftmfd
GEOM 6 2
-0.13044 0.30923 0.22779 0 0.22495 -0.97437 -0 -1
-0.28044 0.30923 0.22779 0 0.22495 -0.97437 -1 -1
-0.13044 0.16308 0.19405 0 0.22495 -0.97437 0 0

Your meshgroup has the flag "1". Does it mean "D" (dynamic) flag?
Click to expand...
No, flag 1 is for no shadows (advisable)

The dynamic flag is for textures that need updating and would look like this:
Code: 
BuckRogers\buck_VC1.dds D
at the end of the mesh file.

The same question. Are UV coordinates needed even if a texture doesn't used (set to "0")?

Yes!

This is the UV bit, did you create it in Blender? (another problem I remember was mirroring, had to flip the meshes).

I think there's something missing, there are variables for flags and other stuff but I don't see them being referenced? But it's probably better when someone else comments on the code.:)

I'm a little confused. If we don't use a texture for the MFD meshgroup (we wriete TEXTURE 0), then why should we use a DDS texture (with "D" flag) for the MFD meshgroup?
Buck Rogers said:

Click to expand...
Yes, I built my mesh in Blender using "Blender Orbiter Mesh Tools". Both square planes that I'm using for two MFDs have correct normals in Blender and game, otherwise they would be invisible.

What the variable do you consider undefined?

You don't. @Buck Rogers was just giving an example of the "D" flag if it were being used for a dynamic texture.

Apologies again for the confusion
The texture flag is NOT needed for the MFD.
My mistake, it's only needed for other instruments.

I was wondering if you had "unwrapped" in Blender or just copy/pasted the UVs.
misha.physics said:

Click to expand...
The variables are being initialised. But as said I'm no coder, have to take a more holistic approach.
Have you tried adding your MFD meshes to your modified (working) Atlantis code?
You could also just export the MFD mesh and make a simple Vesselbuilder .cfg to see if the mesh is at fault?

Thank you all.

I tried both ways.

Do you mean me to edit the Atlantis VC mesh to add two square planes for two test MFDs? Or just using my mesh with the Atlantis Lua script? Not yet, but it's interesting. I should try it.

Not yet, but I should really try it.

Thanks! I need some free time to try it all.
