I dont know of any cheap mocap equipment, but I know a lot of indies will get two vid cameras and manually manipulate the bones. not sure if you had thought of that yet.
Yea, i did try this, and i got tired of it. It takes me too much time and nerves.
Yes, i've seen this. It looks very, very good but the price as you said yourself is the problem. I sent them an email cause i didnt see the price for that suite and they responded that the price is around 40k EURO buahh. Maybe in few years with some luck i open a MoCap studio
but till then...
I was told that there could be some MoCaps for around $1k but i just cant find it.
