They are not really attached when using Vangle() either.

Just look closely at the first branch. (Btw.: I suggest
that you add at least one texture to your trees first.)

The "misuse" of VAngle() just results in smaller angles
when radians are interpreted as degrees. This causes
the disattachments(?) to be less visible.

To see this, just try to increase the rotation angles
by scaling them a little:

   #local ang = VAngle(p0, p1)*4;

Also try:

   #local ang = VAngle(p0, p1)*0;

- which will attach them to each other again.

This means that the rotation of p1 does not make much
sense the way it is done now.

But it seems that you misunderstand something...

I'm not sure what you want to achieve with the rotation
vector above, so I'm not able to guess what your mis-
conseption might be...

Could it be that rotation of objects is not performed
"locally", but "globally" ?

(I.e. not about the axes "local" to objects but about
"global" axes through origo <0, 0, 0>)
