Hello, For those upgrading their engines from 9b to 9c, the only major change to cause a few compiling headaches is if your using the DX library for loading .X files. New interfaces and functions are used to load 'x' files, but its very similar to the old way, just follow one of the samples. After rebuild, no problems found so far. Anyone else had problems going from 9b to 9c? Cheers
