Particle Color & wiggle expression.
Marshal asked 7 years ago
Hey there!
I need to spawn circles that are formed from particles. A directional point emitter with a replicator worked for that very well. At a later point these circles are supposed to distort (turbulence) and dissipate. That was also pretty simple to work out using a replicator with a rotation of “whatever” to make the it a circle. (think of a colorful smoke-ring). Now I need each smoke-ring to be a different color.
A gradient is ok but I really am going for something specific here and tried using a wiggle expression on the color value of the particle. I don’t think it’s working properly. These “smoke-rings” @ 3 particles per second should result in each “smoke-ring” being a different color. Instead each particle is a different color. Is that what should happen?
Comparatively I used particular (through a totally different process) to achieve the same look I was going for and found good results.
Tried the same thing in stardust using a single point emitter and pick-whipped the particle color to a new solid with a “fill” using the same wiggle expression and I got the same results . Particle color doesn’t seem to respect the wiggle expression properly.
Here are the steps to reproduce.
- Add stardust.
- add wiggle expression to particle color “wiggle(3,2)”
- Expose color parameter in timeline and click the “Show in graph” whilst in the not graph editor (timeline?) not sure what it’s called.
- add new solid,
- add fill
- add wiggle expression to color
- Pickwhip particle color to Fill color.
- See all kinds of random colors and compare results in your timeline compared to what’s showing up.
Really digging the update! Great job! This is a blocker for me however :(.
Any chance on a verification of this as a bug or “working as intended”? and when we might see an update? I’m sure you are cranking away at other stuff as well. While this is an issue I am having a great time working with/learning stardust.
p.s. were more presets supposed to ship with the latest release? I learn a lot from them.
Thank you!
