I hope no-one objects to my asking this here rather than in the Blender Artists forum.
I am getting familiar with the Blender pose process (thanks joepal) and want to "freeze" the pose so I can carry out mesh edit with Blender. I plan to create a high resolution static portrait and would like to make minor changes to the model say, eye modifications, teeth asymmetry etc.
Changing from Object to Edit mode loses the pose and resets the model to the imported MH setting. I can't find a method of working on the new posed mesh.
