Well,
one advantage of usingmy old home PC at work for my workstation… Dinner time can be real productive.
After a couple of abortive attempts, (for reasons I don’t yet understand, but will look into later), I have got what I was after.
Done a LW -to- MB -to- LW bit of work, take it home and texture / light it quickly tonight and hopefully get the anim up before my missus demands I spend some quality time with her! 
Just using a std MB motion file (walk/fall) but It’s worked so I’m hoping to be able to play around in MB now.
Just got to re-set the weight maps on the hi-res version so I can interchange them at will.
Starting to get into this CA lark!
