Thank you for your tutorial. It's really useful for new to niagara like me. And your voice is extremely attractive.

[@LeafBranchGames]

Thank you for those kind words. :)

[@eyetoof]

Thank you this was very very helpful!

[@LeafBranchGames]

Glad to hear it. :)

[@CYPHERNATURE]

How do you get the window scratch pad?

[@ouaisetalors]

That was great thanks

[@LeafBranchGames]

Glad you like it. :)

I can't renamed my particle attributes. They're just stuck as "Vector" no matter how many times I rename them.

How can you pass data from one emitter to another using scratchpad?

[@arne1881]

Nice, takk! Endelig noen som bare går rett gjennom og forklarer hvordan ting fungerer. Kort og konsist. Har akkurat begynt å lære meg Niagara, og nettopp kommet gjennom den bratteste delen av læringskurven.. Etter din forklaring i denne videoen, så forstår jeg endelig hvordan disse forskjellige parameterne fungerer! :D

[@LeafBranchGames]

I am very glad to hear that it helped bring you understanding. Thank you for the positive feedback. :)

So basically the ScratchPad is the way to define( or customize) the logic of your specific Niagara system in BluePrint way, right? The only thing that confuses me in such case is -- what is the difference between ScratchPad and Niagara module script(NMS) then? You can achieve similar result with NMS. What are the benefits of SP over NMS?

[@LeafBranchGames]

I talk about all of this in the video in greater detail. The scratchpad is more of a prototyping tool you can use that only will live inside of the system you create it. Then if you feel like the script is good enough and modular in use enough you can create a module script that can be used in other systems. If on the other hand you have something you only want to have use of in one system, you can store it as a scratchpad rather than a module.

Thanks you so much, it's cool
Just, I used Unreal 4 and it's doesn't work to find the NM after creating an asset...the niagara system found only the scratchpad. Maybe the last part is specific to UE5

[@LeafBranchGames]

Hello Karine. There is a property, a drop down, in your Niagara module called "Library Visibility", change that one to "Exposed", compile, apply, save etc and you should not see your module in the category you created it for.

@@LeafBranchGames thank you!!

[@LeafBranchGames]

@@Pikarin_chu You are welcome.

[@aymigamin1933]

Good stuff! Though the effect you did could just be accomplished by having the gravity module itself scaled over time using a graph, right?

[@LeafBranchGames]

There are many ways to achieve the same or similar effect, yes.

[@aymigamin1933]

​@@LeafBranchGames Not a take at the tutorial obvs. Would love some insight in future videos into what you might be able to do in terms of more complex effects with NMS/Scratchpad that you couldn't easily accomplish with graphs, if anything?

[@LeafBranchGames]

@@aymigamin1933 I have plans to delve deeper into Niagara effects in the future, so hopefully I can cover such topics.

[@aymigamin1933]

@@LeafBranchGames I look forward to seeing it =)

Hi, can you make 3d inventory tutorial?
