Hi there, I was trying to create a flickering light bulb effect in cycles, At first I made a filament and gave it an emmision shader and put it in a glass bulb,but that didn’t produce the required effect, so out of frustation I just changed the material of the bulb to emmision and that looked great! ow the thing is I want to make the bulb flicker for a while and then go stable…
At first the material of the bulb transforms from a glass into emmision and then I have to show it flickering, I tried playing around in the curve editor but couldn’t come up with anything special except that I have to do that by hand, inserting keyframes as I move along the timeline…
Is there any other automated or other way to do this… I think that maybe using a noise effect could help but I’m not sure whether that works for emmision shaders or not
there are some dynamic interpolation types like bounce and elastic that may work, there in the curve editor, on the bottom bar, in key -> interpolation at the far right.
Right click on the emission strength and insert a keyframe
Switch to graph editor
select (left click) the strength (top left)
open the properties (hit n)
add a noise modifier
adjust strength and scale
I cant see my graph for the strength… Actually I used a mix rgb shader to blend two materials glass and emission together… First the material changes from glass to emission and then I have to make it flicker… But I only see the graph for the fac value of the mix rgb shader, the curve for the strenght shader doesn’t show up… I’ve tried inserting keyframes on different frames but that didn’t help…
What shall I do?
