Good day everyone. I need to make effect on my environment.

I didn't have any idea. So i am here to ask inspiration.

Do you think billboards alone + particle emitter (with a bit of tuning) could make such effect?

yup the snow, i try and it work well (not visually good thought)

I am trying to make blizzard effect. Since i am not in a country that have snow, i wonder how do i make a visually nice blizzard with foggy effect

I was given suggestion to use billboard blending.

But i dunno where to start. Any suggestion?

(I am playing around with CCloudSceneNode.cpp right now)

How about enabling fog and using 2 different particle systems (or more). The first one should have big particles with a gray bitmap and an alpha value of 0.5 or less that simulates the foggy effect. The second particle system should have small particles (10%-5% of the size of the big particles) and a nearly opaque white bitmap, this would be the snow. Then adjust some values like speed, direction, amount of particles and alpha. I guess an aditional blur effect would make it look more realistic.

besides that, you can even enable fog effect on your map too. if you want more, you can even add motion blur effect so that when the snows fall it will look more realistic.

1) should the billboard follow the character? (set to children and parent)
2) At the start of the game, the particle emitter will move the billboards slowly to the scene. Is there any way to set the particle effect to move to the scene first?
