I have an OBJ Model which is very heavy i want to reduce the size of the model and the model is very fine mesh, i want to reduce the no of polygons.. i need that model to be imported into an iphone application.
There are several solutions. In 3ds Max, you could use the Optimize modifier or the Multires modifier. Outside of 3ds Max, you could use Meshlab to process the OBJ, then import into 3ds Max.
