Hi everyone !
I recently modeled a character in a T-pose, pose it using transpose master and Tposemesh before texturing for presenting purposes.
In those conditions, is it possible to revert back to the original t-pose without having to redo all the textures and changes in geometry? Because I would actually like to rig and animate it 
If you saved your project with undo history then you should be able to switch to the Transpose Master mesh, undo the pose and then transfer the T-pose back to your original model.
Make sure that you back up your model first. It’s not a bad idea to save versions of your model as ZTL files (Tool>Save As) as well as saving the project.
Nah I don’t see any history everytime I save and reopen my file. I guess its lost
