How exactly does the raycast work?
Does the raycast vector describe a virtual box?
Or is it a cylinder? Or a hemisphere?

And has the method changed from FS13 to 15?
I made a mod in FS13 where the raycast worked fine. However now in FS15 I had to adapt several values, but still not works exactly as in FS13.

the raycast "looks" from a point in a direction (like a laser pointer). this example looks 20m downwards:

raycastAll(x, y, z, 0, -1, 0, "findMyNodeRaycastCallback", 20, self)

if the raycast hits something, then self:findMyNodeRaycastCallback is called. it should return false to stop searching:

function ClassOfSelf:findMyNodeRaycastCallback(transformId, x, y, z, distance)
if (condition) then
self.raycastTriggerFound = true
return false
return true

set self.raycastTriggerFound=false before calling raycastAll(), then you know afterwards if you found what you looked for.

Thought it works exactly as in FS13, but hope this helps.

I know - the RC callback handling is no problem.
In my mentioned FS13 mod I had two RC nodes: rc1 front-right-bottom, rc2 back-left-top.
local x1,y1,z1 = getWorldTranslation(self.rc1);
local x2,y2,z2 = getWorldTranslation(self.rc2);
local dx,dy,dz = x2-x1, y2-y1, z2-z1;
local vLen = Utils.vector3Length(dx,dy,dz);
raycastAll(x1, y1, z1, dx, dy, dz, "rcCallback", vLen, self, raycastMask, false);
That worked fine, indeed I got the hits included in this 'virtual box'.
However no longer works satisfying in FS15.

I think there is no box, just a beam. You might want to spawn a trigger shape to get callbacks for the whole volume you defined.
