Concept

The objective for the Easy Ogre Exporter is to be the most simple as possible but with a lots of direct conversions from max scenes, and sure to be free and LGPL.

Current Version

Current version is 2.5.0 Released on December 16 2015

Features

  • One click export from the Max export menu > Ogre scene
  • (DotScene|.scene) export
  • Manage all Ogre versions
    • exports node hierarchy
    • exports node animations
  • Mesh binary export for each objects in the scene
    • shared or Dedicated geometry option
    • vertex Colors
    • normals
    • multiple UV sets
    • tangents
    • edgelist
    • poses from the max morpher
  • Skeletons
    • multiple Skeleton Animations
    • multiple root bones
    • standard structures and biped
  • Animations
    • animations from the main track separate bt time tags or from the motion mixer if available
    • nodes animations from the main track or from the motion mixer for each node in the dot scene
    • poses animations from the main track or from the motion mixer
    • morph vertex animations from the main track or from the motion mixer
  • Materials
    • Standard materials conversion
    • Architecture materials conversion
    • Mentalray Arch / Design materials conversion
    • ambient, diffuse, specular and self illumination colors
    • specular level
    • animated textures from IFL files
    • multi textures
    • multi uv
    • support of composite texture (one layer with mask)
    • transparency level
    • material options like "double sided" or "wire"
    • Shaders (CG and GLSLES) automatic generation for pixel lighting and normal / specular maps / ref cubemap
    • Automatic basic technique for non supported hardware when shaders are used
    • export the textures files
    • optional textures conversion to DDS format with size optimization
  • Lights and cameras
  • Automatic unit conversion to meter
  • Automatic LOD generation
  • Small dialog interface for a minimum of setting like the Ogre version for meshs, prefixs, directories, and some advanced options

 
What coming next :

  • Setup for quick installation

FAQ

1 How to install the exporter ?

  • For Max versions from 2011 to 2015, download the setup from here(external link) and follow the instructions.
  • For older max versions, chose your max version from the SVN directories(external link) and copy the "EasyOgreExporter.dle" file in your max "plugins" directory and restart 3ds Max.
  • Be sure to have the visual studio 2010/2012 redist installed for your system.
  • vs2010 redist x86(external link)
  • vs2010 redist x64(external link)

 
2 How to export my scene ?

  • Just select the "Export" command in the Max menu and choose the "Ogre Scene(*SCENE)" format
  • To export only the selected objects use the Max menu "Export selected"

 
2 Which Scene parameters are exported ?

  • The scene ambient color and background color are exported in the dot scene file

 
3 How can I change the units setting ?

  • The units are taken from the max System Unit Setup, and converted to meter.
  • To get 1 max unit = 1 ogre unit then just change the max system unit to 1 Unit = 1.0 meter

 
4 Which objects user properties are available ?

  • Objects attributes can be added from the Object property dialog in Max
  • renderingDistance, this attribute is exporter in the ogre scene file, it define the visibility distance of a mesh
    • ex : renderingDistance=10.5
  • noLOD, override the LOD generation for the specified object
    • ex : noLOD=true
  • userData, this export a userData markup in the dot scene xml
    • ex : userData=my data

 
5 How can I manage the alpha textures on materials ?

  • The alpha is used from the diffuse texture with a PNG or TGA bitmap
  • To disable texture alpha use the "Alpha source" texture setting and set it to NONE
  • To change the alpha rejection just disable "PreMultiplied Alpha" option on the diffuse texture with an alpha channel (ex: usefull for folliages)

 
6 What extra material setting can I use ?

  • on standard material you can use :
    • the "Wire" option to render your material in wire mode
    • the "Faceted" option to render your material in flat mode
    • the "2-Sided" option to render your material on both face sides

 
7 On which material texture should I set my lightmap ?

  • you should use the ambient texture on standard materials

 
8 Which max materials are exported ?

  • The "Standard material" is the most supported and permit to control the ambient, diffuse, specular, self illumination and bump textures (with shader generation)
  • The "Architecture material" and "Mentalray Arch / Design" only support the material colors and diffuse texture

 
9 How can I set the animation intervals ?

  • This can be defined from the Max Motion Mixer by using clips.
  • The animations can also be defined directly in the track line using time tags (the time tag interface is on the right bottom of the track line).
  • how it works ?
    • add a time tag on the first key of your animation with the desired animation name
    • add a time tag relative to the first tag to set the last animation key

 
10 How can I use the vertex animations ?

  • Vertex animation with any mesh modifier like "Edit mesh", "Ripple", "Noise"...
  • The "Edit poly" modifier is now also supported.

 
11 The exported Mesh appear in black or with a bad pivot, what can I do ?

  • If your model is a simple mesh, apply the "Reset X-Form" tool on your object. This will update the object with the correct transformation, normals and uv maps for the Max exporter interface.
  • You should apply the "Reset X-Form" tool every time you modify the content of an object, and absolutely before you apply any hierarchy or modifier like the skin or the morpher.
  • Since the EOE V0.999 this is less necessary but don't forget that Max need a reset X-Form in some case.

 
12 I forgot to apply the "Reset X-Form" tool before making the skinning of my object. How can I correct that ?

  • You can correct this mistake as follow:
    • In the skin modifier, save the envelope setting in a file.
    • Remove the skin modifier
    • Apply the "Reset X-Form" tool on your object
    • Collapse the modifier stack or apply the "Collapse" tool
    • If it is needed, realign the pivot and redo the "Reset X-Form" and collapse tools
    • Align the skeleton model correctly to the mesh
    • Add the "Skin" modifier
    • Add the same bones as your previous "Skin" modifier setting
    • Load the .env file saved before and match the bones by name
    • Now your skinned mesh should work better in max and export the animations correctly.
