I'm using sweep(point,move,mesh) for testing bullets collisions with mech.
I want to draw decals on hitted mech, but i need dir. Is any way to get it? I'm using phys.ray to test collisions with terrain and it works ok, but I screwed at start and now it would be time-consuming to change all to works good with actors and all build in engine stuff.

you mean "Bool Sweep(Vec &point,Vec &move,.. " ?
you've got there Int *hit_face=NULL
which can return index of the face
if you have calculated face normals mesh.setFaceNormals,
you can access it
base.tri.nrm
or
base.quad.nrm
check comments on 'hit_face' above in the header

but I don't recommend using 'Sweep' for real-time use
Physics.sweep is recommended

But sweep functions takes only basic shapes as an argument.
I saw hit_face, but I still don't see any function that returns quads / tris or any array that store it.

which function are you talking about?

(I'm not sure if you are talking about first or 2nd line ;] )
Physics.sweep takes only basic shapes.
After "Bool Sweep(Vec &point,Vec &move,.. " - i don't know, how to use hit_face to get single tri / quad.

I still don't understand what function do you want to use

Physics.sweep or Sweep
you have also Physics.ray

for Sweep you set a pointer to custom Int
Int face;
if(Sweep(....., &face
{
if(face&SIGN_BIT)..
else
..
}

Ok, I've done it (i just didn't spot MeshBase and didn't know what to do with hit_face).
