How to make Light Streaks?

[Taoizm]

can you post an image of what you're working on?

Hi,

ok this may better explain what i want it to do.

Where the white painted in strokes are is where i want a nice, glowly blue/white light coming up from beneath the yellow and black covers.

but i dont want a full beam of light all around, just a few spots that shine through.

Did that help?

is the "shadow casting' of your soptlight on?
or is that object/plate's material 2 sided? or "enabled cast shadow"

[Jeffo]

Shadow casting is on, the material is a standard material as well... what about the actual parameters of the volume light, the only thing you would have to check is filter shadows right? i have done the streaking effect before but just having a little bit of trouble this time...

ok im just going to ask some things.

1. do you actually hace some holes in the geometry there ?
2. have you tried making the color of the volumetric effect something like red and the density a really high value, that may help you to debug your problem.

2 more things to check:

Make sure your materials are 2 sided, just to be on the safe side.

Make sure that in your light's paramaters "atmosphere shadows" is checked.

Why not just make a bitmap the exact shape of the light beams you want and use it as a projection map?
you can even colour it seperatly. and make it ignore everything, thus preserving a bit of memory cos it's not lighting anything but itself.

Thanks guys!! :)

it was a combination of a few of those... i had the density too low and also changed the attenuation multiplier... much thanks to you!!

heres what i was attempting to do ...


Ian: that would have worked also, and i was thinking of doing that, but i thought it would be more difficult to animate
