PD: it's the copy paste of an old post I made, anyway, it has the info I think you need. In ASpconv you can even combine two or more psd files in one, add png images and move the layers.

I discovered you must open the anme file on notepad or similar and replace all the "," characters for "." then save it and now it's completely functional. Remember, you can only edit a layer if youve selected it from the Layers panel. To add a layer at any time, click on the New Layer button on your Layers panel and choose the appropriate type from the list. It comes with the AS installation, in the Extra Files folder. Picking the appropriate layers for certain jobs is the key, which is why you will find each layer type detailed in the next sections. The only problem is it creates a corrupted anme file which can't be opened on AS. There is a Photoshop script 'Export Layers To Anime Studio.jsx' which will export images in separate layers to an Anime Studio switch layer, containing separate layers. It creates an anme file and a folder with all the png images, it even remember the blend layer mode and it's like ten times faster than the official photoshop script.

Here on forum (I don't remember exactly where) someone posted a link to a japanese software which export psd to anime studio without the need of open or have installed photoshop (personally I work with corel photopaint and sai to edit and generate psd files). Unity uses Animation Layers for managing complex state machines The set of states in an Animator Controller that a character or animated GameObject can be in, along with a set of transitions between those states and a variable to remember the current state.
