cant i scale everything and then ctrl-a and press on scaling?

Yes

Mue's extractor doesn't like scale being any other than 1, so make sure to ctrl-a any object you actually scale. Then it's no problem 

 

Secondly, Mue's LOD viewer could be used to show the ingame size of the model

When you put the cursor on any part of the model, it shows coordinates - which should be in meters

Just make sure that, let's say, the forward most and rear most points of the model sum up to a correct (or so) length

Fixed all the issues i had with the model, now for the technical stuff:

everytime i try to land the aircraft decideds it wants to do a wheelie and not come out of that wheelie, no matter what approach i take when landing.

when i try to take off i spin out (guessing its just the low speed handeling of the game since it doesnt like planes taking off at an angle)

anyone know what can cause this? cg perhaps? The flight model im basing the plane of of is the vampire 5

why not a FM of an aircraft closer to what you have. try the Let-410 (closest cargo plane in size and config i can think of )

I tried using the dhc-6 since it had some similarities to the arava but I didn't like the flight model, then I went to the vampire because it had a similar configuration to the arava (and I'll tweak the model itself to make it less agile), but I'm still not sure whats causing the plane to be so backheavy

all data file coordinates must correspond with coordinates/meshes on the model itself. COG, collision points, etc, 

I hardly see a similar configuration with a vampire...(starting with size) but anyway, try Boxcar data/fm.

Took the vampire because it has one elevator and the forks that hold it and the vertical stabilizers like the arava. It also had 2 separate flaps on each wing (not to mention airbrake) which helped me learn

I fixed most issues in the flight model but for some reason my propellers are always spinning on the Z axis no matter what axis i set it up as, does anyone know how to fix it?

I tried fixing it but the engines still are spinning on the z axis instead of the y axis, no matter what i do. does anyone have any tips?

what other prop birds have you looked at the data ini for?

its genereally a good idea with anything ini related to look up another bird that is similar to what youre working on. compare notes and see whats different

I tried looking at some of the stocks and mods, but then I remembered helicopters have rotors that spin above and I found the RotationAxis field but it also didn't fix it

ah, P-38 Lightning, maybe??? for FM data. might be lighter in GW then the Arava, but twin engined, twin boomed, 2 rudders one elevator

Could that be somehow hard-coded into the model during the construction in 3DS or Blender? Honestly, I have no practical knoweldge about 3d modelling. I am drawing my conclusions from my fiddling with data.ini files in trying to add or fix turning front landing gear and shocks. There are models where no matter what ini dancing I did, the front gear would not turn properly along the correct axis and/or the shocks would not function correctly. That made me believe such movements are somehow hard-coded into the model during the construction in 3DS or Blender. So, my guess is, that unless these movements are planned for and provided for during the model construction, the ini file alone will not help. I would put my bet the same applies also for rotors rotation axis. Of course it would be best if one of our 3D experts could confirm or reject that and shed some more light on the topic.

      Just have found this video and it's pretty good tool for Blender 3d creators .
      Tried Make Human before, but MB-LAB is just genial. You can very easy create soldier, add him uniform and set in needed pose.

      View File LOD Exporter for Blender
      I tried to implement the exporter only based on the information I found by investigating LOD files. I'm not a 3D Modeler myself. I only tested the exporter with rather simple object (hierarchies).
      The bottom line is that I have no idea if the exporter works for you. So please give feedback.
      Note: This plugin requires blender version 2.78 or 2.79. It is not compatible with blender versions 2.8+.
      1.) Installation
      Open the Blender User Preferences - Add-ons Tab
      (File -> User Preferences... -> Add-Ons)
      Click "Install from File..."
      Browse to and select the exporter python script "io_export_sf2_lod.py"
      Click "Install from File..." (or double click on the script name)
      In the Add-Ons Tab under Supported Level select Testing and enable "Import-Export: Strike Fighters 2 LOD Exporter"
      The LOD exporter is now installed and enabled. Under File -> Export you should see the menu item "Strike Fighters 2 LOD (.lod)". It's greyed out until an exportable object is selected.
      2.) Usage
      Select the object you want to export and click File -> Export -> Strike Fighters 2 LOD (.lod)
      The file browser opens. In the lower left area you see the LOD exporter options:
      -enable/disable writing the out file (text file with information about the exported object(s)).
      -enable/disable animation export
      -allow decals:
          This option is similar to the option in the original TW-Exporter: "Exporting using AllowDecals=0 causes the vertex to be shared, so it can reduce the size of the .LOD but also causes decals to "bleed" along the edges."
          This dialog setting is used as default for all objects to be exported. However, it can be overwritten by each individual object via the custom object property "AllowDecals" = 0(false) or 1(true)
      The selected object and all child objects are exported.
      Two custom object properties are supported by the exporter:
          -AllowDecals = 0 or 1, This option is similar to the option in the original TW-Exporter: "Exporting using AllowDecals=0 causes the vertex to be shared, so it can reduce the size of the .LOD but also causes decals to "bleed" along the edges."
          -UseFlatNormal = 0 or 1, if set to 1 then all vertex normals are pointing straight up (normal = (0,0,1)) in the objects local coordinate system.
      Please note!
       
      The objects must meet the following requirements:
      -No scaling in the Transform Properties allowed (that means: scale x = y = z = 1.0). If your object has scaling, it should be applied to the mesh (Ctrl-A)
       Scaling is only allowed for animations.
      -A material must be assigned to the object. Only the first material of an object is exported.
      The following material parameters are exported:
          -Diffuse Color (the lod file format also contains ambient color. Currently the exporter set ambient color = diffuse color)
          -Specular Color
          -Specular Intensity
          -Specular Hardness (I think in 3ds Max it's called glossiness)
          -if "Shading -> Emit" > 0.0 then self illumination is enabled
          -Transparency (if transparency is enabled, then the object doesn't cast and doesn't catch shadow. if transparency is disabled, then the object cast and catch shadow. The specific LOD format version the exporter writes, doesn't support arbitrary cast/catch shadow combinations. The other LOD formats I don't understand enough (yet). Sorry!)
          -Alpha
          -Mirror Reflectivity
          -Diffuse texture image name (as diffuse texture the exporter uses the texture where "Influence -> Diffuse -> Color" is enabled)
          -Normal map texture image name("Influence -> Geometry -> Normal" is enabled and the Normal value is also exported)
          -Specular map texture image name("Influence -> Specular -> Intensity" is enabled)
          -Normal and specular map can only be used together with a diffuse map. (If I exported a normal or specular map without diffuse map, then the LOD wasn't shown in the game or the game crashed. I don't know why...)
          
      Animation Export:
          
          This exporter supports the following object animation types: location, rotation and scaling.
          Frames 10, 20, 30, ..., 100 are exported as animation 1
          Frames 110, 120, 130, ..., 200 are exported as animation 2, ...

      3.)Credits:
      Thanks to logan4 and angelp who provided me with specific lod files that helped me to understand the lod file format better.

      4.)Changelog:
      Version 0.1:
      -initial release
      Version 0.2:
      -bugfix: didn't work in blender version 0.79

      Hey there,
      for some time I'm trying to learn Blender to finally create own models one day. While some things are quite easy to achieve, others give me headache... So are there others around, that play around with Blender and try to be creative? ;) Maybe we can share our knowledge and help each other out with tips, hints and so on.
      A first problem, that I'm fiddling with atm and that I don't really get:
      Wing was smoothed and Autosmooth is set to 60°. After cutting the Slats out, the leading edge of the slat is still smoothed, while the wings leading edge isn't anymore. What can I do, to get rid of this?

    • By mue
      This is the first release of the LOD Exporter for blender.
      A main reason for this release is to get feedback / bug reports from you users (3D Modeler). I'm not a 3D Modeler myself. I only tested the exporter with rather simple object (hierarchies). I tried to implement the exporter only based on the information I found by investigating LOD files. Thanks again to logan4 and angelp who provided me with specific lod files that helped me to understand the lod file format better.  
      The Bottom line is that I have no idea if the exporter works for you. So please give feedback.
      The Exporter Script: Update: The latest version can be found in the download section: https://combatace.com/files/file/16747-lod-exporter-for-blender/
