Multitexture has no color parameters and it helpless with Multiscatter. I'll explain: if we have bunch of objects that is scattered with multiscatter and randomly placed by hands too, than we can't use same material to randomize its colors this way. For example trees or grass plants and so on. If we wount have a texture on object we can just use multiscatter texture with random colors mixed and that's the trick. But for now we must use random solid texture files to mix them in multitexture and use different material if we need it on multiscattered objects. It is no good... But if it is really hard to implement in Corona I see no way to ask You forever about it :(
