I used shape keys to create a middle shape between other two. Can I now remove shape keys and 'apply' them as a modifier to the resulting mesh?
Try creating a new shapekey by pressing the arrow under the add/remove buttons and selecting new shape from mix:
This will create a new shapekey from the current mix. You can then delete all the shapekeys, making sure you delete the new one last.
This gives you a shapekey-free mesh with the shape from the original shapekey mix.
You can use the Corrective Shape Key addon. It's under Community > Animation in Addons.
Once installed, just find the desired blend you want, press the black triangle in the Shape Keys panel and choose Create duplicate for editing. This will apply the state and create a new copy while preserving the old one with the keys.
There is a way most people don't know (because blender has way to many funtions) and i had to figure this out on my own because google just failed to find a usefull answer to this common problem.
how it goes:
Go ---> File -> User Preferences -> Select Comunity Supported Level---> Category= Object -> Oscurart Tools.
tick it to active and !!save settings!!.
select the mesh you want to copy (no edit mode needed)
press enter to open the search funktion and then type : mesh
2,5. make sure its typed with small letters and spelled the right way.
2,75. if this happens:
then you dindn`t select the mesh.
but if you get this option`s you did it the right way:
- select: Object to Mesh
Done. Now you have a copy of the mesh the way you setup the shapekeys and or pose but without shapekeys.
note that it also applies modyfiers like subsurface etc.
and because its a copy you stil got the original mesh with all modifiers, bones, shapekeys you started out with.
