示例1: prepareMaterialInstance

                                              unsigned int idx, int tag) {
    if (tag < 0) // Should not be here if the polygon is sky textured
        OPDE_EXCEPT("Non-instanced material instance requested");

    mat->setReceiveShadows(true);

    Ogre::StringStream lightmapName;
    lightmapName << "@lightmap" << tag;

    Pass *shadPass = mat->getTechnique(0)->getPass(0);

    if (shadPass->getNumTextureUnitStates() <= 1) {
        // Lightmap texture is added here
        TextureUnitState *tex = shadPass->createTextureUnitState();
        tex->setTexture(mLightService->getAtlasTexture(tag));

        // Blend
        tex->setColourOperation(LBO_MODULATE);
        // Use 2nd texture co-ordinate set
        tex->setTextureCoordSet(1);

        // Clamp
        tex->setTextureAddressingMode(TextureUnitState::TAM_CLAMP);

        // Switch filtering off to see lmap pixels: TFO_NONE
        tex->setTextureFiltering(TFO_BILINEAR);

        // update that definition
