[BioEve]

Hello!
Unsuccessfully I've tried to create my custom extension and I could really use some help to recover these file :
maya (.mb)
Zbrush (.ztl)
Wavefront Object (.obj)

Thanks a lot!

I need three short samples of each files. Please, send them to raptorbck (at) gmail (dot) com.

Thanks for the reply, I will sent the files asap.
Anyway, there is only 1 thing I don't understand in the tutorial : the reason why I should add the number 21 to the Bytes.
I mean, I don't think it's a fixed number, so what does this number refer to ?

Thanks!
