Rob,
i set both particle and strand orientation but nothing changed after , i
used align to surface node. in opengl view instances oriented correctly
but when i render it is different.

Sandy, just so you know because it isnt that obvious, it was me that
wrote that tutorial :) also Arda, I imagine the orientation problem
you are having is because they are all on a sphere rather than a grid
- are you taking the spheres normal into account regarding the
orientation? And as for OP, Morten am not sure why your orientation
is having the effect it is, perhaps because you are setting the
orientation only on emit then doing something else that effects it.
try putting the orientation back on as the last step in the ice tree.
best regards

Here ya go - it is that system that Rob mentions, I added more
particle segments to allow more accurate collision - but otherwise
the same thing - you can add forces such as wind into the mix on
the particle setups - it is a really nice method to do it!
Cheers

I can send you a scene I developed based on a technique I
came across somewhere to do awesome simulated strands, by
creating particle systems to loft the strands between and
doing the sim on the particles - this allow you to set
orientation on the particles and then the strands - I was
using it to do grass and bushes being flattened by a vehicle
and I had the bushes/grass randomly oriented as I was
rendering a field using strand deforming.

Yes i tried a feather instance on strands but i couldn't set
the orientation...

try the loft ... checkbox in your create strands compound.
and if you use the sitoa strand compound, there´s also
one for the
rotations.
not sitting in front of xsi now, but sure you´ll figure
it out within
one minute ;)

I just need to randomize of the geometrys
y-rotation, and according to the docs and
pointers given here earlier this should do the
trick, but no go. Is there a magic step I might
have missed to get it working?

I have a nice setup which creates lovely
grass deforming geometry instances on strands
so I can have turbulent wind moving the
strands around. I am using Emit Strands for
this, but I seem to be unable to randomize
the instance y-orientation using a Randomize
Rotation by Cone - they are unaffected by
this. If I create a different setup using
Emit from Geometry and Create Strands on
that, I can control the y-rotation, but then
the instances are upside down, and my non
simulated turbulence does not work.
How can I get to control instance y-rotation
when using Emit Strands?
