I use blender with the TD body, but my poses are always off and I'm tired of the back and forth

When I make poses for my kids, I just use the Anypose hud. That way I can do it in world and make sure it fits them correctly. It's a little more limited than using an outside program, of course, but their poses aren't generally too complex.

You can always save the pose to work on in another program, too, if you want the head tilted a bit more or something like that.

Thank you aliciachenaux Persey! I bought animare but I knew I should have went with anypose. I think I'll invest in that soon
