particle rotation
 

hi, i've got particles instanced with a piece of geometry. An expression control the rotation -and they totate nicel in x y and z. Unfortunately now I only need them to rotate around one axis. Is there a way of somehow locking, say y and z and having them only rotate around x?

any help would be nice;)

thanks

Yes. I'm not sure what your per particle attribute is callde, but it could look something like this.

rotPP += <<0.5, 0, 0>>;

thank you very much. That realy helped me! I am just beginning to learn how expressions and mel work. This might be an absolute beginner question, but the << at the beginnig and end indicated that it is a vector?

That's correct. Then each number separated by a comma correlate to <<x, y, z>>, or if you are using th vector for color info <<r, g, b>>

thanks again :beer:
