If ever there's a 2010 version of TE, will it be possible for you to do motion capture? Well lots of games out there including tennis are doing this. There are also available mocap online, some are free and some needs some investment. If that will happen, TE will certainly kick those Tennis games out there and will attract more gamers
. Regarding the ball physics, I am very satisfied with that already but if needs improvement, the better. Keep up the good work Manutoo.
