Texture Sampling with Niagara Particles in Unreal & TouchDesigner - Tutorial

[@bb-kd3pc]

You are so great at explaining things, thank you so much for this tutorial

[@TheInteractiveImmersiveHQ]

No problem! We'll have more unreal content coming soon!

[@3ddavid796]

Thank you again for the great tutorial, can you guide us about pass Touch designer point cloud to Niagara advecgrid?

[@TheInteractiveImmersiveHQ]

I can add it to the list for sure!

Thanks, glad you enjoyed it! We've got lots of great Unreal content coming up, so stay tuned!

Great tutorial! Trying to do something similar with TD -> UE which is to generate and manage my Kinect Azure point clouds in TD and pass my PC texture to Niagara for particle spawn positions. I understood what you did sampling the texture for 2D color, but what if I wanted to use that texture for position sampling instead? Any help would be greatly appreciated! Many thanks.

[@TheInteractiveImmersiveHQ]

Thanks! This definitely sounds possible, I would look for some more advanced Niagara tutorials, especially any that deal with generating the particles from point clouds. Once you've got the connection from TD -> UE set up, you should be able to use the texture to control the appropriate parameter

Please do you know if this is possible with shapes that aren't grids? I am importing static points from Houdini and using them as particles, I wish to 'project' a texture from above to 'pixel map' these points. Thanks a lot!!!!

Am I able to control the Niagara particles from unreal in Touchdesigner? how to do it?

[@TheInteractiveImmersiveHQ]

Definitely! You can send OSC control signals from TouchDesigner to Unreal to control a Niagara particle system. See our videos _Unreal Engine + Kinect for Immersive Experiences_ (kzbin.info/www/bejne/m5C7kJiejtWoos0) and _Controlling Virtual Lights in Unreal Engine via OSC from TouchDesigner_ (kzbin.info/www/bejne/hoKkloihmN6ejNE) for more info

You'll have to download and install the plugin from the Marketplace. Here's a link to it: www.unrealengine.com/id/login/api/login?client_id=43e2dea89b054198a703f6199bee6d5b&redirect_uri=https%3A%2F%2Fwww.unrealengine.com%2Fmarketplace%2Fen-US%2Fproduct%2F92307b570d474fbc87592b973ce82e3b%3FsessionInvalidated%3Dtrue&prompt=pass_through

You can find it by searching for "Spout" in the Marketplace and their "Livestreaming, zero-latency, DX12-compatible bidirectional cameras for SPOUT/OBS" plugin should be the first result
