Hi Surazel,
This mod looks delightful, can't wait to give it a go. However I don't use OBMM anymore as I prefer to stick to Wrye Bash's BAIN system (prefer to have a single method of installing mods). Is there any way to install the various animations using BAIN instead?
Funny you should say that - I have recently converted most of my OBMM installs to BAIN. There are some exceptions to my migration and Sensual Wals is one of them. The reason it uses OBMM is that for both the Animations Installer and the Sensual Walks Installer there are some quite complex processing that is required. This includes renaming of ESP and KF files as part of the installation process. In terms of BAIN, there would be far too many permutations to make it something that people could install properly. I took a long look at how it might be done and concluded that it was far too difficult and error prone.
That is a very long way of saying "I'm afraid not"

My own experience of migrating to BAIN is that there are some mods that are safer to install with OBMM as wells as managing my OBSE installs. The mods that replace Meshes and Textures are almost always worth trying to convert to BAIN because of WB's superior tracking of restoring things when you deactivate a mod. Mods that install unique files and ESPs (such as Sensual Walks) will not really get much benefit from being converted to BAIN, because there are no complex restores - the file are either installed or deleted.
I did post a request for Script support on the WB thread - one can always dream

Finally, of course anything is possible - you could work out what animation files need to be copied and what the target name needs to be. If you look in the "Sensual Walks Animations Installer\Fwalk Mapping\All available female walk animations", the file name is part of the target KF file name (append it to "0FemaleVariableWalk_" to get the full name) and the file extension is the name of the source KF file that needs to be copied. If you do decide to embark on this route, you may find the "Customising the Animations Installer" optional download helpful.
Hope this helps
