Gobo Lighting Question

Recommended Posts

Hello,

i am afraid i am still on my projector tip. Is it possible to use a photograph (jpeg) and map it on to a volumetric light so that it projects the image, like a slide in a slide projector.

thanks in advance

just apply your image to the transparency channel then place the material onto the light

model a star shape or some shape with hard edges that are jaggedy and then project a volumetric light through it.

made a spokey thing and rotated in front of light, but does not create hard volumetrics? a light setting perhaps. still can't get anything close to the real looking beams in that trailer

thanks for the suggestions

first thing volumetric light wont go through a transparent texture.

here is a quick scene

the setting to fix the artifacts it the "sample distance"

(changing sample distance increases render time)

Gone back to my texture gobo as i think it looks closer. changing the sub to 1m creates a huge render need for or 5 of these lights.

Hello,

thanks looks nice. certainly a quicker render will try and combine some of the two ideas.

cheers for now
