I downloaded this file with armature and mesh online. In the file, the armature and mesh are in a specific pose already. But the mesh does not have the armature modifier applied to it. Although I can see that the mesh has all the vertex groups and weight painting as per the armature and is well aligned with the armature.
I want to reset the mesh to a T-pose or A-pose, but if I apply the armature to the mesh, the mesh deforms very weirdly. After that if I remove all pose data from pose mode, what I get is the mesh in the same pose as it is now.
How can I get this mesh into the rest mode along with the armature?
