Making collisions through blender

[karan20000000000]

Is there any way to generate collisions through blender for an object?
I've tried exporting the object as .obj, .dff, .3ds but all of them showed errors (invalid file format, non standard dff, etc) in gmax probably due to large size of the object. [Note: I did triangulate the faces of the object before exporting.]
I also tried setting the collision type to autogenerate, the object appeared but the collisions didn't seem to work for this one probably because of huge number of faces (around 55k )
I searched google to generate collisions through colleditor but neither were there any tutorials nor did the official website show up the documentation page.

There's a reason why I was trying to export the model to gmax, that is, just to generate cols. But, as I've already mentioned, I've been unable to do that because of the errors. Anyways, thanks :]

The same thing happens to me though

save your progress as .3ds open in 3ds max or gmax and export collisions

edit: but in this way i got some rotation problem to axis Y ( creating dff in zmodeler and exporting col through 3ds ) so i just set Rotation axis Y to -180 and it worked

So, apparently a friend of mine (Perikiyo) taught me how to make collisions through colleditor so this is no longer required :]
