[@toldme3d]

So happy to see you here !!! Greetings from Athens and VJ Codec !!!

[@BogdanRunceanu]

"Return Normalized Exec Index" - brilliant! :) Great tutorial, BTW!

[@vjfader]

i use it all the time :)

[@ChrixB]

Finally someone explain the Niagara options in detail and how they work together and not just tick things around, thanks !!

[@ChrixB]

I just made the tutorial with UE5 and it works like a charm! Your are a master !

[@shimlaDnB]

Best niagara tutorial out there! thanks for putting this up, i learned a bunch of new tricks :)

[@vjfader]

Appreciate the comment, this mean a lot as, I can say the same about your tutorials :) it opened the door for me

[@sebastianbaalbaki1704]

great tutorial! there are not many vjs doing tutorials in ue4... PLEASE make more!!

[@zeitgeistcowboy]

Thanks for the tutorial! It's an insight into a VJ's technical mind.

[@vjfader]

I'm glad this tutorial was helpful to you, nice to hear a constructive comment :)

[@JohnTosom]

It's so easy to understand Niagara how you explained. Thanks.

[@vjfader]

Glad it was helpful!

[@denefty5189]

It’s very important video for me! Thanks a lot for your tutorials!!!!! It will be great if you continue do that , if that possible 💥💥💥💥💥💥

[@mrhmakes]

awesome tut! Thanks so much for this. I just stumbled into you channel after researching unreal visual analyzers and you're just taking it to another level!

[@vjfader]

Glad it was helpful!

[@darkbibni]

Definitely the best explanation I found so far! Thanks for this!

[@STVinMotion]

Way to go @vjfader! Thanks for sharing your knowledge and making it an audio reactive world 🙏

[@vjfader]

Glad it was helpful!

Thank so much VJ ! This is super awesome!!

Glad you like it!

Thank you for sharing this amazing stuff!!

[@allhellbreaksloops]

So incredibly helpful thanks so much for sharing your knowledge with the community!

[@vjfader]

You are so welcome!

[@truewiking]

Great explained, Thank you very much 🙏

[@unrealhabitat]

This tutorials are amazing! I would pay a monthly subscription to see more of these being developed, get access to the project files and so on. Can you do these in Unreal Engine 5 capturing audio from a mic?

[@vjfader]

Yes

[@SaiNarayan_]

This is incredible, thank you so much for making this!

[@gabridntdnt9071]

Hi, is there a chance to see this tutorial redone for 5.3? thx

[@sunn2000]

Awesome tutorial. Thanks!

[@vjfader]

You're welcome!

[@ashoakenfold]

Good tutorial! Thanks!

[@민균박-f1b]

awesome video! thank you for sharing

[@terramidia3d]

Awesome and simple to follow! Thank you! Is it possible to render this with the Movie Render Queue? I tryied to do so, but it not reacts to the audio. I added an audio track to the timeline, also without success. But if I use Sequencer Render (not the movie render queue), I have the audio reaction, but with problems, like lack of sync and the limitations of the sequencer render.

[@vjfader]

for Microphone audio input, you can not run through Movie Render Queue as it is not real-time, instead you can use a pre-recorded audio WAV file in a timeline sequencer

[@SynthToshi]

nice work!

[@vjfader]

Tnx

[@aravkumar14]

Please create more tutorials.... 🤩🤩

[@vjfader]

ok, I will :)

[@wmka]

I'd like to know how to control the niagara parameters using midi controller. please and thank you.

[@VisualBeatLab]

Hello for scratch dynamic input the "map get" only had "input default" how do I change the "particle attributes to output"? particles position is empty no x y z fields.

[@muneebhamza8917]

How would you make the Niagara system only listen to a specific sound source and not every single audio playing in the engine?

[@vjfader]

You can use a submix

[@webdelete6654]

@@vjfader but have you actually gotten this to work? I've seen and experienced myself that niagara only listens to the Master!

[@moxom3854]

Have you been able to figure this out? I have also tried to get Niagara to listen to a new submix, pre master submix and can not get it to work.

[@muneebhamza8917]

@@moxom3854 no I couldn't

[@davidpereira4455]

Nice! What's your gpu btw?

[@KuyruksuzSatyr]

Why my inputs in scratch doesnt show up in the system overview? I cannot set up audio or any other custom inputs because of this. Did exactly the same as in the video but there is no "look at position" like in 8:41

[@vjfader]

It’s hard to answer without seeing a screenshot, make sure your data type for output is correct, for example can’t use float output on vector3

[@pnth2344]

Hello, you need to do this : in your scratch pad, under the dynamic inputs list, right click your scratch dynamic input - in this example it is supposedly named "orient to center" - and choose "apply changes". Every time you make changes, the "*" character will appear as a suffix to your dynamic input; once updated, it disappears. The input does not update automatically when saving the niagara system, which is why you could not find the "look at position" vector.

[@bendeformnewmediaartist6566]

First Question always when i am new in something. How i can render it or Record it ? Thx for this amazing tutorial love it.

[@vjfader]

I'm using NinjaV external HDMI recorder, plan to do a review video to show some features

[@mrhmakes]

I managed to do it in Unreal 4.27 by adding a lifecycle track to sequencer AND rendering in MRQ (old render legacy method does not seem to record the niagara AV reacting)

[@supremebeme]

subscribed!

[@vjfader]

tnx!

[@Ren-gr1me]

at 6:33 I dont have "orient mesh to vector" option -- I think its different in 5.1 anyone know the equivalent?

[@Ren-gr1me]

>> initial mesh orientation --> Mesh Orientation Mode: Orient to Vector

[@Ren-gr1me]

okay now at 10:00 im stuck. my cubes dont stretch out like that. they stay in their singular form and move out towards edge. I followed step by step, the only difference is that in 5.1 when you connect lookAtPosition to Normalize Distance Range it creates a new node to convert the input to a position. Then, in my NS system, the "lookAtPosition" does not appear underneath my scratch pad name. I'm quite confused as to why my meshes arent rendering extended like yours but I feel like it has something to do with these updates?? Not expecting you to have an answer just sharing my experience in 5.1!! :)

[@vjfader]

maybe you need to add a forcer to move the cubes out from center?

[@user-lc5ms9gy3e]

@@Ren-gr1me hey, did you ever get around this? I'm also trying to follow in ue5

[@hartonopatrick]

Hi James, thanks for this! So after watching the video, I'm kind of understand your creative approach with Niagara. So basically, the spawning particle always based on the specific mesh, including the material you prepared previously, right?

[@vjfader]

yes, I almost always use Mesh particles in my visual designs, unless they are glowing dots

[@陈亭羽-c5o]

May I ask how to set the Z axis of the Cube model to face outwards?

[@vjfader]

what do you mean? depends on your 3D model, it has a up axis that determines which way is up

[@mvix7793]

How i can render it with music and animation in sequencer ?

[@vjfader]

i usually use my external HDMI video recorder, or you can record using OBS as it's playing

[@abduljabar7]

mantap👍👍

[@MusicMidiVisualizer]

is also made with the Unreal Engine kzbin.info/www/bejne/nn_daJmogsSZiq8

[@amirmohammad2795]

I can not do it in Unreal engine 5.4, anyway thanks!
