I am trying to make dynamic system based motion with numerical method.
So I need to keep angular velocity and angular displacement of each grass instance.
Which is the reason I am using Niagara.
I really don’t want every grass particles to be updated whether they are visible in the camera or not.
I just want to update the motion of the visible grasses.
What I want to do is remove grasses when they are out of sight, and re-spawn the grasses when they are at the sight and update their motion while they are remaining in the sight.
This is off-topic of this post, but I am a newbie to Unreal Engine so I don’t fully know about PCG, so I’d like to ask.
Is there a feature in PCG that allow you to update per instance custom data of spawned meshes in each frame using some compute shader?
Thank you for leaving replies to my post so far by the way.
