A few WIP tests learning Niagara.
Go easy on me, as its only been a month.

Going for etheral ghost, but this is early days WIP.

A cool accident :wink:

This is only particles with curl noise, no flipbooks or any materials.

Any pointers on how to make smoke trails using Ribbons? I imagine an effect where particles emit off a skeletal mesh, and ā€œdrawā€ swirling ribbon shapes using curl noise, then the ribbons themselves swirl a bit. And hopefully I can use a nice smokey rendered flipbook (or even just a material using noise) that can flow the texture down the UVs of the newly created ribbons, adding more smokey motion, etc. Imagine a ghostly effect but with really nice crisp smoke, like many cigarette trails emanating.

Cheers!

Little update with some Ribbons progress. Hopefully I can get this working with Event Handlers and children emitters to create what I envision.
This test was manually cloning two emitters and sourcing from a different vertex. I hope this can be done procedurally where I can easily setup 100ā€™s of these ribbons across the mesh. Any tips? Cheers!

error

A strange but cool mistake attempting to use Event Handlers.
Using Sample Skeletal Mesh I scatter particles all over the mesh. I then use a Location Event to spawn the RIbbons.
The flashing is from the parent particles dying. I am having trouble spawning parent particles that stick to the mesh and donā€™t die as I spawn my smoke ribbons from these.
It seems this method may not be the best way as the ribbons somehow do not like the dying parent particles, even with required persistent ids.

I want these ribbons to stick to the mesh as if they were hairs, so when the character walks, they trail behind but still follow the actor.

I know there is a better way but am lost at the moment. Any ideas?

Cheers!

Slight update trying to use Local space and a burst of particles that never dieā€¦ just need to figure out why they are not following the animation of the mesh, and only its transform. Also need the ribbons to inherit the parent velocity so they donā€™t just rise upwards.

HAHA, I figured it out! (Of course with some help from some of you :wink: )
Was using the completely wrong modules!

The proper method is to use Initialize and Update Mesh Production Sprite modulesā€¦ works a charm! Cheers!

Some dry ice ethereal Niagara Ribbon tests, no tesselation.

Looks much smoother and curvy with Tessellation but am getting errors with many ribbons emitted.

Here is a test with less ribbons and no errorsā€¦ now with floor collision. I really like the wisps from inherent velocity.

Another cool accident. :wink:
Gives me some ideasā€¦ in film I could use this as a pass for this locked down shot and in comp mess with the actual colored final shot, make the character a bit transparent, deforming, etc. Is there a way to use this greyscale in realtime to somehow do some shader tricks to make the character look more ghost like besides refraction?
