actually in my case, when i used wine (BMax file compiled with Windows OS) its OK. it will run as it is.. but when it comes to Linux execution file (BMax file compiled with Linux OS), it will show u the wrong Z Buffer issue thing... Mark or anyone from BlitzSupport please look at this, we just wanna know which is the problem coming, is that fault cause by our machine or BMax compiler.. i just dont wanna spend too much time on drilling in our hardware n machine, and the end of days u guys will saying that is bacause of BMax compiler issue instead..
