Posed rig for sculpting?

I have box modelled figure and have rigged it. I would like to pose the figure and then sculpt details into the posed figure.
Is this possble? ie to freeze a pose.

Assuming you are using the armature modifier, just click apply and your mesh will stay in the position its posed in. You can then go in and scultp and do whatever.

Just know you can’t go back after applying (unless you undo).

Thanks, will try
