Anyone can tell me how to rotate particle instances?
I tried rotation pop but it doesn't give me control over the angle and axis separately.
Any tips?

Thanks you for the answer.
I forgot to mention that I already have a velocity orientating my particles, what I wanted to to add is some rotations to it, for example in the Z axis where I can thumble my particles with random values or a ramp based on it´s life.
I could do it with scale using VOPs but I didn´t figure out how to do it with rotations. I really didn´t understand how to control particle with the rotation POP when you have 1 angle controling 3 axis.
Can anyone help with this?
Sorry for the bad english

After the particles are aligned to the N (or velocity) you can use the ‘rot’ attribute to do an additional rotation.

The Rotation POP creates the attribute for you. Or you can do it manually.

Thanks for the reply.
I am aware of the rot attribute and rotation POP, the problem is I could´t figure it out a way to use it to rotate each axis with different values, for example:
X = 25
Y = 45
Z = 90
The parameters only allow me to set one angle for the 3 axis not one angle for each axis, I know that must be a way to do it right.
I also tried VOP but also I couldn't make it work right, it doesn't follow my angles right.
The only example file in houdini that´s available has an error and does not work right.
I also looked at the link that Wolfwood gave me but I didn't find my answer there either.
I just need a little help to understand how it actually works.

WOW!!!!!
That´s it, that´s the key I was missing!
Man! Thank you very much Wolfwood! this was taking my sleep away.
That helped a lot!!!
I would like to ask help for on more issue if you or anybody else might.ops:
I would like to make my particles to auto bank as they turn, I tried to work with the up vector node but i didn´t have much success.
Any tips?
Anyway thanks very much again for the help everybody. :wink:
