hello. i can't figure out how to get a random value between two numbers. in maya i just type rand(8,10).
how can i do that in houdini? i couldn't find anything helpful in the functions list.

in VEX:
where seed is the random seed (often @ptnum in a point wrangle)

in hscript expressions:
assuming the point number is the random seed

thank you for your reply. the code seems working. but somehow doesn't solve my objective…

Maybe you ought to mention what your objective is?

i want to emit a ring of particles. so i created an emitting object, have keyed emission so it bursts for one frame only, and then set the velocity variance to x=10 and z=10. but so the particles are emitting not as a ring but as a circle. my thought was that the variance goes from 0 to 10, but when i have used your code nothing changed. they are still moving as a circle filling whole radius.

Hello guys,

Jumping here because I have a similar problem.
I have this Point Replicate set to 20 to uprase my Vellum Grain.

How can I replicate a random number between two values on a per point basis?

Thank you

You could do like toadstorm said and use a point wrangle with a code like this:

Or use the attribute randomize sop set to Set Value and specify the min/max values. If you want a float value, change the Dimensions to 1.

Thanks mkps, someone on odforce told me about this new node (attribute adjust integer) that does just that!
