Hi Kemal, Over the last 20 years I've had the opportunity to use most of the major spline modelers on the Mac platform. My favorites have been the ALIAS products and FORM-Z. Now I'm primarily using SHADE 7 PRO. I do concept and illustration so I really don't need more animation capability. SILO is the poly modeler that I'm playing with now and I've just discovered MODO. I've been wondering how much more evolved MODO is compared to SILO. I wish there was a MODO demo but... Do you have positive or negative impressions about MODO that you'd like to share? Do you use it in a production environment? Bottom line... what more could I do with MODO than with SILO. Is it worth the extra $$$. Thanks for your response :^)
