Water Plug-in BP_FluidSim_01 Not Working

Development Pipeline & Plugins Plugins

I’m currently trying to get some water mechanics to work from the Unreal Engine Water plugin.

The ripples/wakes the boat made used to work just fine, however after a project crash they only seem to work when the camera collides with something else and gets pushed closer to the boat. I’ve tried mimicking this by shortening the length of the spring arm to have the camera be super close but the wakes to not appear for me at all when I do that.

I’m guessing the problem has something to do with either BP_FluidSim_01, or M_Fluid_Sim_01 (both of which were open during the project crash, and both responsible for the element currently not working)

Here’s a video to show you what the problem looks like - BP_FluidSim_01 Only Works when camera collides - Album on Imgur

I’ve already tried uninstalling and re-installing UE5 (as the plug-in is engine content) but it still doesn’t work on any projects.

Even the Fluidsim_Terrain demomap doesn’t seem to work for me.

I hope someone here has the knowledge to help me dig myself out of this hole :slight_smile:

I found out why the BP_FluidSim_01 didn’t work and why there were no ripples behind my boat. For some reason the water plugin’s ripple system isn’t functional with a ‘cine camera’. Hope this helps someone in the future

So could you please tell us how to fix that problem? Is that related to Lumen? Thanks!

when you look at the blueprint code, using ‘follow player’ option makes it use camera manager to get the camera and uses it’s position as the simulation center, which I guess can make it appear like it’s not working when simulation is too far from the actual pawn. just a speculation.
