'Basically what I need is this but as true 3d model. Mine is only using an image as reflection so if you turn it sideways it's still flat." Say it's not so, you mean the world isn't flat after all? Seriously, i often check out this web site for free software http://www.nonags.com
Here is one i found, not sure if it would do what you are looking for though.

Many of the models that you create with the help of 3D modeling tools, as well as some models converted from CAD software can be very complex. These models may consist of hundreds of thousands, even millions of polygons and are practically useless for processing in real-time visualization systems.
VIZup is an easy-to-use tool for reducing and optimizing 3D models. With the help of VIZup, you can reach the optimal balance between the necessary details level and the size of 3D models. You can also use this software to reduce the number of polygons for your 3D models used in virtual reality and real-time visualization systems. Decreasing the size of 3D models stored on the Web lets your users and customers download them much faster. Besides, this product can also be effectively used for Level-of-Details (LOD) generation.
