Hi does anyone here know how to use Niagara with sequencer. I have a fountain that I want to turn off an on at certain times during playback. Right now I put the fountain in Sequencer and added a Niagara component and then put the system life cycle track in there and adjusted it to the time range that I want then copied that red life cycle to a few more spots on the time line and only the most recient copied Life cycle with play. None of the others fire. ??

Hi everyone, thanks for your wealth of knowledge and help! You guys have shown some really cool things that Niagara can do!

How would I go about animating the UV0Offset in Ribbon Renderer over time?

In a system or in the sequencer?

I tried following your suggestions about adding a User Parameter to the Emitter module but it does not seem possible.

I wonder if this is not implemented and you cannot animate anything in the Ribbon Renderer?

Cheers!

Animate a dynamic parameter, then use that in the material to create the offset.

#351

Cheers,

Please bear with me as I am just learning Niagara. I am speaking about the Ribbon Renderer settings, not the Ribbon Material (as I cannot see any control for UV0Offset in the material either)

Cheers!

Add(TextureCoordinate, Dynamic parameter)
Use that result pin as UV input for your texture

Any robust info on Event Handler Execution Modes? Can not seem to find any info.
Events seem to only work when set to Spawned Particles and not Every Particle?
When would you use Every Particle? Confusingā€¦

Cheers!

Hi all! Iā€™ve wasted couple evenings - but canā€™t find any way to use particle collision event in BP. I need to spawn decals at particle hit position. Maybe someone already did this thing? Thank you.

I was also struggling that i needed decal on particle collision so i did it another way. There is bp node for niagara is emitter position but it not give you per particle postion so what i did make a event for collison and they second particle which will emit on collision will have per particle location in blueprint. And one more thing emitter location node is missing in ue4.25

#359

#360
