Collision detection failure ?

[TakanoFukada 0]

Hi,

I tried to add a 'Geometry' in O2 to for collision detection... it worked well with 'Men' units, eg: they were unable to pass through the object. The object was supposed to be a static crate.

However, when I attempted to drive an armoured vehicle or just a car through this same 'object', I could go through it.

Similarly, when I model a vehicle, I can drive through buildings !!!

Can anyone please kindly help me out on this?

Thanks !

What mass did you assign to your geometry?

[TakanoFukada 0]

for the crate, i placed the Geometry's 'Mass' as 50...

for the vehicle, i placed the Geometry's 'Mass' as 2000...

anyway, can anyone please explain to me exactly how does this 'Mass' thingie work or is there a standard reference figure?

thanx !

You also must make sure that the surface is closed and you must find the components (use "find components" function).

How I assign the mass is:

Make the geometry lod

Use Cntrl A to select all, (I do "Face", "Recalculate Normals" at this point so you can see your object better)

While all is selected in Geometry, use the

Structure,Convexity,Component Convex Hull

(This makes selections out of your object)

Then while all is still selected,assign the mass in the bottom left corner.

I'm fairly new and as far as I can tell that is how to assign mass and get the geometry working.

These aren't the problems I am having,I am having problems with geometry because I am trying to make a HighRise and am going beyond the limits.
