When I import a 3DS or OBJ model it will show up, but as soon as I
check the "Geometry Affected" check box in the "ODECollision" tab
(generated by the ODECollision plugin) and run the simulation, I get
the generic error:

"dance.exe has encountered a problem and needs to close. We are
sorrry for the inconvenience."

If I debug the error in Visual Studio 2005, I see:

"Unhandled exception at 0x057148ed in dance.exe: 0xC0000005: Access
violation reading location 0x00000000."

And it takes me to this code in a_map.c:

/* allocate enough space for wide chars */
inwbuffer = (wchar_t *)_calloca( inbuff_size, sizeof(wchar_t) );
if ( inwbuffer == NULL ) {
return 0;
}

I tried a WRL file, but the model never showed up. Am I doing
something wrong?

Thanks,
Dave
