Dust in light

by Levi Putna · in Torque Game Engine · 09/11/2006 (10:33 pm) · 6 replies

What I am trying to do is create an effect of dust passing throw a beam of light
Very similar to the lighting kit demo.
www.synapsegaming.com/content/linkedimages/TLK-Demo2.jpgI have a copy of the lighting kit but cannot workout how to do this.

I am a little rushed for time, so can anyone help me out with a quick step by step guide in doing this

Thanks in advance.

You can use a Volume Light combined with either a particle effect or a Precipitation to emulate this I beleive.

I am only new 2 the lighting kin, got it 3 days ago.

The light shows up on the ground and walls but I can't get the beam visible. Eg, like in the image above.

The image above isn't shining an actual beam of light as such. It's a texture attached to the light. If you look at the lights in the TLK demo level, the one with that big green pool of goo, inside you'll see some lights that do the same thing. Examining them and their datablocks might help you in replicating the results. The dust is just a particle emitter node.

Thanks,

I got the beam of light working with my texture, and the particle emitter working, although it looks more like someone has started a fire in my cave rather than dust floating around, but i can work on that. I was looking at the Tim Aste Environment Pack #2 and notes the dust fx and the fx in the highlands.

Precipitation FX could look more natural in a contrasted lit environment, as the dust floating around would be be mostly invisible when it's not floating through the lit areas. There's no particular tutorial beyond looking at what is in the datablock for that pack. It's not that hard to come up with such an effect on your own, just look at the settings for precpitation systems and try messing with them along with different kind of textures.

Thanks everyone,

I got Rain/Snow and lightning working and created a very bad dust storm :o). I think that the Precipitation FX is a much more powerful tool to create the dust, it seems that the light effects the Precipitation much better than particle effect.

Give me a few days to refine my skills and I will post a screen shot.
