I would like to ask if anyone create Assetbundle in Unity on cloud? I would like to generate the AssetBundle dynamically on cloud and the client app will download it accordingly.
Could you let me know your idea? Is there any cloud service for hosting Unity ?
AssetBundles require unity pro to build. There is a command line batch mode that you can use to build your asset bundles automaticly and host it on virtualy any host (a simple HTTP get).
Remember that you might not need asset bundles (or unity pro) - you can easily download textures and audio from the web using the WWW class. For textures you can use png, jpeg and tiff, for audio wav, ogg (only desktop and webplayer), mp3 (only mobile). Mesh loading should be also possible but that will require additional tools.
