Hello,
Is it possible to set layers from .psd files?
I did find layersets in the SDK, but i cant find a way to set them.
PSD Layersets

Here a code I did 6 months ago. So it's not the cleanest but it's working and since this subject is not very well documented I guess It gonna help you 
def setAlpha(self,path,shader) :
if path.endswith( ('.psd' , '.PSD') ) : #PSD
bc = c4d.BaseContainer()
bc.SetFilename(c4d.LOADTEXTURE_FILENAME, path.encode('utf-8'))
tex = c4d.modules.bodypaint.SendPainterCommand(c4d.PAINTER_LOADTEXTURE, doc=self.doc, tex=None, bc=bc)
if tex is False:
print path
return
layer = tex.GetFirstLayer()
layerName = layer.GetName()
layermode = c4d.LAYERSETMODE_LAYERALPHA
c4d.modules.bodypaint.SendPainterCommand(c4d.PAINTER_FORCECLOSETEXTURE, doc=self.doc, tex=tex, bc=c4d.BaseContainer())
else:#tiff, But if you already know the name simply use this
layerName = 'Alpha'
layermode = c4d.LAYERSETMODE_ALPHAS
layerSet = c4d.LayerSet()
layerSet.SetMode(layermode)
layerSet.AddLayer(layerName)
shader[c4d.BITMAPSHADER_LAYERSET] = layerSet
If it's an psd it load it and have a c4d.modules.bodypaint.PaintTexture object.
Then now you are able to list all the layer. I my case I always used the first layer, but you can loop using GetNext/GetDown, in other way if you already know the name of the layer simply use the exemple for the tiff
Then after you just have to create a LayerSet and set thoses data.
Hope it's helped

Little extra question:
I have a test code that can find a psd layer by name and then sets it. but it returns only the name. I need it to return the path in the psd. like somefolder/somefolder/lmb_tp
right now it only returns the name of layer that i'm seeking.

I did it for object but since BaseObject and c4d.modules.bodypaint.PaintTexture are both BaseList2D that change nothing.
I comment it(maybe too much? :p) but if you still don't understand a part feel free to ask
