[Jay]

there, can you help Dan?

[Jay]

ah yes, take out that function and what do you get?  Carpediem's sh-3 build!  lol

[Dan East]

No, I can't ICQ. Start debugging again so you get the error. Then hold your mouse over the lp2 and lp1 variables. A tooltip should appear telling you the values. I need those please. Also, I need to know what called that func (if it was through recursion or not, might be running out of stack space). When it stops with the error, click on View->Debug Windows->Call Stack. At the top of the list you will see the current function, and down below is the stack of functions called to get to that point. Please copy the top several functions and paste them here for me.<br>Thanks!<br><br>Dan East

[Jay]

ok, one sec

Okay, the real problem is in D_DrawSubdiv. It's passing bad int pointers to Recursive Triangle. I'm looking...<br><br>Dan East

[Dan East]

Next step , I need you to tell me the value of the pfv var in D_DrawSubdiv. That var is assigned in the begging of the function. You can set a breakpoint to the line after the assignment using the Hand toolbar button. Or, you can let it crash as it has been, then double click the D_DrawSubdiv function in the call stack.<br><br>Dan East

[Jay]

pfv isn't giving me a value, it's not even in the context window for the func.  ???  By the way, when I do look at the context menu, it says error expression cannot be evaluated for vertindex and facesfront

[Dan East]

Make sure you have the D_DrawSubdiv function selected in the call stack (there will be a yellow arrow next to it). You can also just type in pfv in the watch window (in the name column).<br><br>Dan East

[Jay]

it says error, symbol pfv not found

[Dan East]

Did you try setting a breakpoint on the line after pfv is assigned in D_DrawSubdiv?<br><br>Dan East

[Jay]

no, let me try that

[Jay]

it won't give me that

[Jay]

it'll give me all the other variables, just not that
