In c++, everything is possible as there is a direct access to the engine,
you can even generate a mesh from code, like this : http://wiki.maratis3d.org/index.php?tit … coded_Cube

Hmm, so will there be the ability to edit a .mesh file from the LUA side in future release where I could adjust the diffuse color of a material from withn the code? I am guessing this could happen with a plugin to the editor I guess? I am really thinking of digging into the C++ side of Maratis, but I just want to see if I can get something done on the LUA side, since that is the side most new users might prefert to use, and then the might go to the C++ side for more control, or to add their own custom features.

note that when you modify an asset, like a texture or a mesh file, it automatically refresh it in Maratis editor.

What format are you exporting from 3dsmax ?

- if you are exporting a Collada or OBJ file, you can use Maratis converter :

Open your project in Maratis
Clic on File > Import 3d model and select your 3d file
It will convert the file and save it as a XML .mesh in your-project/meshs/
Open the .mesh file with a text editor and search for your material nodes : "Add this inside the material (check the local path) :

Here is an example of a material in Maratis XML format (from a mesh found in the second link I gave you) :

Hi,

you can find details on how to link shader in Blender here : http://www.maratis3d.org/?p=277
And there is some examples of shaders here : http://www.maratis3d.org/?p=548

In the example, the shaders are in the "shaders/" project folder.
It uses classic glsl shaders (vertex + fragment)
using custom uniforms and attributes sent by the engine.

For example this attributes for the geometry :

attribute vec3 Vertex;
attribute vec3 Normal;

Or this uniforms for the matrices :

uniform mat4 ModelViewMatrix;
uniform mat4 ProjectionMatrix;
uniform mat4 NormalMatrix;
uniform mat4 ProjModelViewMatrix;

..hi guys..i went trough forum, and i couldnt find details about shader creation/specifics, regarding Maratis..i know Maratis uses GLSL, but appart from that, there is no specific details related to shader creation for engine. Is there any tutorial/documentation for it ?
