Unreal Engine 5.2 PCG Tutorial - Water Plugin

[@Romain_Derelicts]

Thank you for this awesome and clear tutorial, Michael! That's the only one covering rivers/lakes with PCG. For people using UE 5.3 or UE 5.4, the trick to have the meshes covering the whole river will not work. To fix it, you need to tick the "Unbounded" box on the "Spline Sample" node. :)

Amazing content ++

Thanks for this; I like how you created the points for the rocks using the intersect. I adapted this to use a surface sampler. Using the z height seems crude though, what if your world was not flat and you had rivers at different heights? Perhaps distance to the river spline points?

[@MichaelRoyalty]

Yeah it is crude! I hadn't known how to use spline sampling on horizontal when I made this video. It takes a slightly different tweak to get it working, but it's a better method than filtering on z.

A good video. The trick where you rotate for 90° and the reset the bounds doesn't seem to work for me. Is there any other way or am i missing something?

This is outstanding, you can definitely get the best of this tool. Thank you so much for this series.

Have you noticed any issues with your spline BP not responding or becoming "crashy"? Great tutorials btw! I ask because for some reason when I make a child BP of the parent spline PCG, it gets wonky and died after trying to review nodes /etc.

[@MichaelRoyalty]

I haven't experienced many crashes in this case, but PCG is still in the experimental stage and I've crashed it many times. Since the water plugin is also experimental I'm not surprised you're encountering crashes. You could try inspecting the nodes to see how many points you're getting, one of the most common crashes I've encountered is trying to debug a node when there are far more points than I expected (IE millions of points), and inspecting can give you insights into that without being quite as heavy a load.

I notice in your PCG tutorials you use always use a spline in a blueprint instead of the PCG volume in your level. Why is that?

[@MichaelRoyalty]

I tend to prefer using a spline in blueprint, because it gives finer control over the bounds, and it also lets me scale things a little more incrementally -- by moving a single spline point instead of expanding the scale of the PCG volume. But mostly it's just whatever I feel like using at the time, there's no good reason one way or the other.

Hey i really love your tutorials! I wonder if you wrapped ur head around pcg functionalities like the fallen trees, which they showed in the demo. Are you planning on doing a Tutorial on that some time in the future?
