Efficient Falling Snow

rob.ert

I've got a winter-themed game, and would like to have falling snow in the background. Is there any efficient way to do this? Perhaps using particles, etc? Thanks!

Could you not animate the background? Would be the simplest way I think...

A single tposition just off the top pf the camera view actor oscillating over the x axis position dropping particles at random intervals would work too.

My first thought was animation too. But I'm a procesural guy because I can tweak the fx at runtime. Example, blizzard or rain is the same actor different particle.

Less r, more CPU. Not much though.

Either method will work. Animation if you can do it.

What about layering a few backgrounds of snow flakes and animating them at slightly different speeds and directions?

Try tiling the snow and then interpolate Y on an oversized actor in a loop the distance of the texture sample height.

Also....I've never tried it but maybe you can tile an animation behavior and make a small animated swatch of snow falling. You would just need to be clever on how the animation texture loops.

The new update of Bumps has some nice snowflakes in the new snow levels...

Here is a demo I just posted if you desire:
