Snow falling off a foot?

[Holzi]

Hey all,

I've got a character (huge robot) walking on snow and I've like to use Pflow for snow that gets lifted off the ground and falls off the foot as the character walks.

I assume perhaps a collision with the ground and the bottom of the feet being emitters is the way to go?

Can anyone point me in the direction of a tutorial as I've not delved in to Pflow much.

Thanks
pretty much right. though you cannot test the collision for your emitter. so if you want the particle system to kick in shortly after the foot lifts off the floor you might need to have a workaround (e.g. one 'father'-particle that lifes forever, does not move at all, and if that hits the floor, it sends out new particles or something like this).

to your tutorial question: you might want to have a look at this (http://www.tutorialized.com/view/tutorial/Rain-Tutorial-for-3D-Studio-Max-PFlow/22408)

Thanks for the reply. I thought this would of been a pretty straight forward use of particle flow. :argh:

I go at this like that:

Seed1 particles that are following the foot;
Seed2 particles get spawned from seed1 when hitting a deflector just above the ground, and are following the foot;
Active particles that get spawned from seed2 when it hits a deflector a bit above the first one

This way you will only get snow getting created on the up move. You'll need other elements too ;)

sounds good. Basically the same thing I said, just with proper english and also in terms with pflow ;)
