Hi Orhan,

> In moi3d you can edit how much polyons / quality of the mesh you need?

Yes, you can adjust a slider to make either a higher density or lower density mesh, the controls are described here:

If you e-mail me at moi@moi3d.com I can get you a new 30 day trial set up.


> If i buy the v3 now, get i the v4 in the next months?

I'm sorry I don't know yet - when v4 is released there will be an automatic update available for people who purchased v3 within a couple of months or so before the final release but that will be retroactive from the final release and I don't have a final release date set yet. We could be a little bit outside that grace period right now.

You would be able to use the v4 beta release right away though.
