Houdini Niagara Updates Sept. 16, 2020, 2:17 p.m.
903/5000
Hello everybody! Thanks for the great tips!
I need help, please: It's about blueprint interactions with Niagra systems. I am currently building a VR Dataviz.
I have this vellum grain simulation with 148,000 points. I successfully imported the animation of the point cloud into Unreal with Niagra. The spheres are rendered as sprites. The shader is just a flat, round disk with a normal sphere.
The animation runs real-time in unreal. The frame rate could be better but it works.
I would like to implement an interaction: When the VRPawn enters the holographic disk, the Niagara system should stop and pause at the highest point. As soon as the VRPawn is no longer in the hologram, the Niagara system should continue to run. Unfortunately I couldn't find any video on Youtube that could help me …
The video is rendered with Blender and is for viewing only. The last image is a screenshot form UE
Update: I figured out how to pause the system by entering a trigger volume. It works but is not reliable. Does anyone have any suggestions for improvement?
Furthermore, I would like to address a specific point in time within the loop duration (11.6s). For example, the system should pause at second 7. Right now it pauses right away the VRPawn enters the trigger volume.
Many thanks in advance
