As far as I can tell PS did away with the 3d tools. I have the subscription so it the latest version. Just a little caveat there. However, AutoDesk Mudbox's 3d painting tools bridge directly with photoshop; live. As in the changes you make in photoshop will update back to Mudbox and vice versa. Mudbox also supports UDIM uv tiles by default (LF is UDIM), Layers with layer styles, Custom brushes (it's easy to convert ABRs for use in MB), Photo Stencil projection painting, Normal, AO, Cavity, and Displacement painting and baking, and more than that. The brushes/ tools also support custom curve creation (created in mudbox via it's curve tools) for exact strokes and such.

Not to mention it's sculpting tools.

Once you get the hang of the interface, which is very much like Poser's really, very minimalist, and the import and export process, working with Poser figures is a breeze in Mudbox. It maintains vertex order and also makes scaling a total non issue with no fuss. By far it's the best 3d painting software you'll find for the price, putting Blender's tools to shame.

Mudbox is 10 dollars a month.
