Nodes not attaching! What am i doing wrong?

[My_KBalls]

Ive got an issue where my nodes aren't connecting - they are snapping to each other but dont connect (go green), other nodes on other parts can, even other nodes on my parts can but not the ones i want to connect.

Can anyone shed any light.?

can it be something to do with the collision mesh not being exactly to the node?

Cheers

I've had this once, when one node had it's Y up, and ths other had it forward..

they need afaik to be rotated so they align..

afaik, this is fixed by adding 90 to one of these node defining numbers in cfg file
