int subsetIndex Index of the model subset to replace, should be less than SubsetCount.
Material material The new Material, cannot be null.

Changes the Material for the subset to a new one!


for (int i = 0; i < model.SubsetCount; i++)
    // GetMaterial will often returned a shared resource, so 
    // copy it if you don't wish to change all assets that 
    // share it.
    Material mat = model.GetMaterial(i).Copy();
    mat[MatParamName.ColorTint] = Color.HSV(0, 1, 1);
    model.SetMaterial(i, mat);
