I'm here appealing to the Poser Python illumanti on the possibility of using this to merge animation layers into the base layer.  From a cursory examination of the Poser Python documentation this doesn't seem possible, but it would be edifying to have a final word from those who know better.

Thanks!

I dont think it would be too difficult , its just moving the keyframe data from one layer to another.

I will have a look at it for you  :)    , doesnt poser have a "merge down"   feature , or a cut and paste ?

I finally managed to have a look at my Poser system and sadly there doesnt appear to be a python method to change between animation layers :unsure:  nor does there seem to be a merge command .  :sad:    

If you save an animated pose set and save the layers , when you load it , it gives an option to merge layers and apply them to the base layer .

That's interesting.  When you say 'animted pose set' you mean a pose containing the animation into the Pose library, correct?

This would do exactly what the person is requiring - merge layers to the base layer.

yes , a pose saved to the pose library , and selecting to save the frames .
When loading the pose you get an option to merge layers to a specified layer .

Thank you very much for the clarification. :)
