Hi Aurelien, if you ask the hardware to create the mipmaps for you ( setUseHardwareMipMapGeneration() ) they are generated automatically. Otherwise you can write on a given mipmap level yourself, see the "level" parameter of Camera::attach() method.
I believe that if you use setUseHardwareMipMapGeneration() on a Texture, its mipmaps are generated as soon as the texture is compiled, but I'm not 100% sure about this anyway.
