I get this question all the time, and as of right now no, most mobile devices couldn't handle it or it would be really laggy. You could port the modding but it would take a really long time because the particles and the blocks are made differently into the game then the pc's version.
Yeah, go ahead, I don't have much experience with iOS devices and you could probably do it a lot faster then I could. You can post it. just give me credits for the shader and you for the ios transfer. But if possible don't use mega download, they seem to change the urls sometimes and it requires an app to download the file. Mediafire or dropbox usually work better. Thanks
