I'm currently looking into UDK Ultimate and PhyreEngine at the moment and have ran into some problems. Has anybody been able to compile any of the samples of PhyreEngine? There are binaries in Tools/ but i'd like to be able to create my own PKG HDD boot games without using a file serving directory, which the binaries provided currently only seem to do. Currently when compiling i'm basically getting a load of errors from cl.exe trying to compile the code, which doesn't seem right at all. AFAIK PhyreEngine uses batch scripts to compile and link, convert assets and package up builds. Also has anybody had any success with using UDK Ultimate? I've had a bit of a look at the code and as far as I can see it should support HDD booting aswell as BD booting as the code grabs this from the PARAM.SFO. I've managed to package up a binary which simply loads the files from the file serving directory (like PhyreEngine) but not straight from the HDD itself. The source code compiles, though. Any help would be appreciated! UPDATE: I'm now able to get PhyreEngine to compile properly after using the Repair function of the SDK installer!
