Great tutorial thanks! There is a slight work-around the issue that we can't have this working on update. Not ideal but still cool to experiment with. Basically you need to set your emitter update to "Self" with a loop duration between 0.02-0.04 and then a particle life of 0.1. You can then use a render target to feed an animated texture in to the particle system. This is quite performance heavy and can be slightly optimised by using the kill particles module and kill particles depending on the alpha (look at the the content examples).
Thanks so much for making these videos. Is there any way to do a similar thing with the particles mapped to particular meshes UVs so they only show up in the masked area, or scaled by the white value of a texture?
Great tutorial! Can i use the same system to make the particles spawn in another location, like a sphere, and make them get attracted and "form" the texture?
Hi! Hope you are well! Say you have a texture with 2 colors or more, is there a way to have a force, vector for example, only effect ONE of the colors? Maybe not, but worth asking😅 Thx in advance 🙌
hey man! really helpful tutorial thanks. One thing I'm trying to do with your method is using an NDI video receiver texture to create partial emission but I can't figure out how to update the particle system every frame.... is this even possible?, would be very grateful if you knew how to point me in the right direction. struggling to find anything else online. :)
This is really good, but I need to be able to do this (and the kill alpha particles part) using a _volume_ texture sampler. However, the volume texture sampler doesn't have a UV parameter so the whole thing hits a dead end at that point. Any ideas?
Hi, Thank you as this is very helpful! Now I want to do this with sample texture from image sequence. That said I believe it would not work since this is applied to spawned and the texture needs to be updated...correct?

I needed this today, Damn!
Thanks so so much, great and to the point!

Thnx. A lot..

Thanks for the tutorial. Is it possible to pass custom HLSL to niagara instead of using texture sample?

Never mind! It was 'Sample Pseudo Volume Texture' I needed.
How would you do this same technique for a static mesh location for example, or a skeletal mesh?
Having trouble doing this in unreal 5. The sample texture doesn’t have the UV part.
i did this on 5.1 with no issues
is this possible for static meshes intead of sprites?

Correct. Your mind is in the right place!
@@gamedevoutpost9270 figured out a way to do it via Houdini Niagara point cloud with CD attribute. Not sure about efficiency though.
@@eyadarabi4262 You might want to try sampling the texture in particle update.
Only can use in Particle Spawn? how to update it
I wanted to make a tutorial on this, but unfortunately it is not working in 4.26. In due time my friend.
