[ODE] Triangle Mesh Problem (Another one :P)

[Julian Spillane]

Hey all,

I've been having a bit of a problem with triangle 
mesh collision. To be specific, some meshes of 
mine seem to work with it flawlessly, while 
others don't seem to be parsing the vertices and 
indices in the same way as they're being 
displayed.

For example, I created, in 3D Studio MAX an 
inclined plane from a box. Nothing too 
complicated. So, I exported it to a .3ds file, 
parsed it into my engine, converted the vertices 
into an array of dVector3's, converted the 
indices into an [n][3] array of ints, and then 
passed them all in. My object simply fell through 
the plane. So, not one to give up, I made a 
sphere. I parsed it in, yadda yadda, and my 
object seemed to interact with it flawlessly.

Now, this poses a big problem to me as I don't 
know what to fix. And yes, before anyone asks, 
I've ensured that the data I'm passing in matches 
the vertex and index data of the model. I'm just 
stumped. :/

If anyone can help, it will be greatly 
appreciated.

Best Regards,
Julian Spillane
