Material - A material determines how the surface of a {LEX()}mesh{LEX} will appear after being rendered. You can e.g. assign {LEX()}texture{LEX}s, set colours, enable lighting or {LEX()}shadow{LEX}-receiving as well as assigning {LEX()}shader{LEX}s.

Normally it's just visible from one side (e.g. surface of a {LEX()}mesh{LEX}), but this can be changed (e.g. for {LEX()}water{LEX} surfaces). Material properties can be defined by material files or by source code.

Transparency

If you have problems with transparency, look for some important material options.

• Set scene blend to alpha blend
• Disable depth write

Depth write can be turned off when rendering static backgrounds or when rendering a collection of transparent objects at the end of a scene so that they overlap each other correctly.

Apply in material script:

material TransparencyExample
{
    technique
    {
        pass
        {
            //...
            scene_blend alpha_blend
            depth_write off
        }
    }
}

Apply by code (C# example for Mogre):

myMaterialPtr.GetTechnique(0).GetPass(0).SetSceneBlending(SceneBlendType.SBT_TRANSPARENT_ALPHA);
myMaterialPtr.GetTechnique(0).GetPass(0).DepthWriteEnabled = false;
