I’m using the default 2D waterfall which came with the example contents projects and the waterfall culls the particles depending on the camera angle.
You can see in the video that a front on view results in the particles being cut off but with a side view the particles can be seen going over and colliding with the rocks.
Grid2D_Flip effects this, turning it off gets rid of this issue but then the spray is too chaotic and it doesn’t flow and collide with the rocks.
Any idea which settings I need to change?
Go here in your Niagara system, whether it’s in a blueprint or just in your scene and set your bounds from 1 to 100 until it stops disappearing. I usually just set it to 100.
What you can also do is this:
This sets it in the emitter itself per emitter. This is if you’re using GPU render for the emitter and with fixed bounds set. By set I mean you will probably need to have them set to:
-1000x -1000y -1000z
1000x 1000y 1000z

Interesting. I will test that out!
Did you ever find a fix for this? I’m having a similar issue where my particles get very faded when near surface and the camera is directly facing it but isn’t faded when looking at it from a side angle
That’s odd, it looks like the geometry is causing a weird z-draw issue with the particle system. Is it overlapping too much or something? Because it’s jet black on other parts of the geometry of the house.
