Hi Marco,

just wondering... have you ever worked with clients?

Clearly communicating with clients and approving the design steps until the product is finished
should be IMHO mandatory if you want to avoid such thing you have mentioned, especially if
you use toolsets not having parametric input options, where you can do changes on the fly, in
every step you do.

I would let your clients approve every design phase (sketching, modeling, texturing and rendering)
to avoid surprises. Otherwise start all over again and make it clear to your clients that they will be
charged accordingly.

Best regards
Stefan
