I want to know how I can call and open the bvh export menu from my python operator (button)? I've looked into it and I found that the class INFO_MT_file_export(Menu): is located in the space_info.py but I couldn't find except the collada no bvh.
So first, I want to know how I can call and open the bvh export as shown below from my operator?
Also, I've used Blender's operator_file_export template for this and edited it to export bvh instead, and it also adds a menu item to the export menu, I wonder how I can add the Rotation dropdown list and the Root Translation Only shown below to my menu item created?
So to wrap it up, I want to know how to open the bvh export window from my operator, and also want to know how I can get the bvh export parameters to add them to my panel menu.
