Exporting from Blender

Install

• Download Maratis Exporter for Blender.
• Start Blender and go to File > User Preferences > Add-Ons > Install Add-On
• Select Zip-file and check Import-Export: Maratis mesh
• Save As Default

Maratis mode

Select Maratis in the Blender Render menu, it will enable special panels for Maratis.

Materials

IMPORTANT: Only the green boxed in areas are supported

Maratis materials are a bit different than Blender materials, only some features are supported (see the green boxes) and they are real-time oriented.

An additional panel is visible in the Material properties:

You can choose between 3 modes for Maratis materials :

• Fixed is used for old generation 3D using multi-texture only (mostly deprecated today).
• Standard is the simplest mode, it creates a classic material using diffuse, specular, normal-map and emit.
• CustomShader is the mode to select if you want the material to use a specific glsl shader, shader samples here [1].

The BlendMode specify what type of transparency is applied to the material.

Texture slots

If you are using a Standard material, the texture slots needs to be used in this order:

The only Type supported is Image or Movie (though movies are not supported yet).

If you are using a Fixed or CustomShader material, you can use up to 8 texture slots:

In glsl, texture slots are accessed using:

uniform sampler2D Texture[8];

Supported Image sampling

Supported Image mapping

Supported Mapping

Supported Influences

Only active in Fixed mode for multi-texturing blending.

Skinning

Maratis only supports Vertex Groups skinning, be sure to turn off the Bone Envelope option. If you don’t want to do the skinning manually:

• Select your model, then select the armature (both need to be selected)
• Go to Object > Parent > with Automatic Weights > select ‘With automatic Weights

Animation and multi-animation

Export

Select the objects you want to export and go to File > Export > Maratis mesh. Don’t forget to select the Armature(s) with the Object(s).

Keep in mind

In general:

• Be sure your textures are in Your-Maratis-Project/maps/
• Export the meshs to Your-Maratis-Project/meshs/
• 10 units is equal to 1 meter
• Use 60 fps frame rate in Blender for animation

When working on large objects, like a full level with multiple rooms, try to separate the mesh in multiple Blender objects (for example, one for each room). When exported in Maratis mesh format, each object will become a SubMesh. Why?

• For a better visibility detection (only visible SubMesh will be draw).
• For more dynamic lights. Maratis standard renderer only uses the 4 closest lights of each SubMesh.
