from a quick glance it looks like it should be showing on screen - i myself never really went with using pretransformed matrices, but just cuz you don't see it - doesn't mean it's not there try using xray debug tool (it's in 5933), play with modes and see if the invisible triangle doesn't just miraculously appear after altering a setting. it's a really nice tool to use for just such a debug problem

the app say's my app isnt debug but in my configuration it's set to Debug do you have any kind of instant messenger? if you do can you PM me ur handle? thanks Jbone

[fghjj]

add

CODE

g_pD3DDevice->Present(NULL, NULL, NULL, NULL);

to end of loop

ok please dont hurt me since i made this topic yesterday i figured i'd post my current problem

ok when i add those audio functions in my main loop it goes to a black screen when i launch my xbe and yes i know the includes above are for XACT but i've been experimenting all night with a way to play music and it seems my Direct Music isnt working i know somewhere i made a stupid mistake and the one who corrects my code will think im retarded but it's been a long night and im leaving this code to a proffesional to fix so i can learn from my mistakes
