BOA, Michael - MANY, MANY THX for your quick response and your help!! I apricate that very much - you made my day :-) !! - I bought moi3d for about 2 weeks together with some tutorials on gumroad and I'm working about 12 hours/day to be ready as soon as possible - but compared with poly-modeling in c4d I made so much progress within this time where I needed about 1 year in poly-modeling :-) :-) - and there is so much fun working with it!! I'm with the original moi v3 Release (as with every software I 'm using it in production) and not beta - but do you recommend the v4 beta? As far I had 0 (null - zero!!!!!!) problems - unbeatable - I love this!! The only wish I have :-): I'm working with c4d since 2013 and there is 1+LMB = pan, 2+LMB = zoom, 3+LMB rotate - this costed me so much time to change that behavior and to navigate in moi3d - if there is a possibility to make this allocation individually, that would be surely an advantage. Are there many new features from v3 to v4? Hmm, I think I have to watch out for v4 :-) Again: - MUCH thanks a lot for your help!!! Best, Robert
