Hi Ayad Mohsen, what you need is to add a socalled alpha channel to each texture.
You need to add this in Photoshop/Gimp/etc and save it as a 32-bit .tga or .png texture. You can use Google to find tutorials that explain how to add an alpha channel to a texture in Photoshop.
When you're done, assign the 32-bit texture to your model and import the model in Lumion.
Then apply a Standard material to the surface in Lumion, and set the Reflection or Clip slider to maximum, so that it uses the alpha channel in the texture as a clipping mask.[/li][/list]
