Question by DaveA · Sep 30, 2010 at 07:59 PM · screensizeparticlebillboard

Particles sized to screen, not scene?

Using 3.0f5.

I have these particle systems, billboard aligned, and it seems that, no matter how close or far the camera is, the on-screen size is the same. Thus when I'm far away, it looks like a giant cloud, but in near, it's tiny compared to the object the emitter is near.

Is this expected? I don't see any 'scale to screen' implying settings. I need them to scale properly (that is, not to the screen, but to the scene)

Set the max particle size to something larger than the default .25. Keep in mind that huge particles can cause fill-rate issues, which is why that setting exists.

No sorry. All that did was draw bigger particles, same size on-screen no matter the distance from the camera. Can we post pictures here?

You can link to pics. I'd guess your particle sizes are too big in the first place, because otherwise particles naturally are smaller the farther away they are. The only thing that would prevent that is the max particle size limiter.
