One of the things most of us who do companions also like to do is show them off; but screenshots of NPCs just standing around tend to get boring, so we use posemods for setting up all sorts of lovely and oft intricately choreographed shots.
For Oblivion, there are quite a few mods that have such things - some tame, others... less so.
In my trawling of teh webzorz this evening, I came across a link to one I wasn't familiar with for Oblivion, by the name of "Goma Pose".
"This is a compilation of all the pose mods based on CTAddPose that I have created since a few years ago; consisted of 16 esp files, a whopping total of 815 poses are available."
This, I think will take some time to go through... and many (most?) players will likely never make it to the finish line in a mod this size.
Still, it should offer up quite a few possibilities for those of us who still play the old, archaic game.
Fair warning: I haven't actually tested this mod yet. I've downloaded, but not had a chance to fire 'er up. With 30 endorsements and no thumbs-downs, I figure it can't be too broken, though.
I'm sure I'll have some screenshots to show off once I do get a chance to test it.
