Thanks, that's handy. I knew alignment was a big topic haha but I never faced an actual issue because of it until now. I'll have to learn how to make better use of VS debug tools/RenderDoc. Could by handy...

Thanks. I'll have to see what Visual Studio offers for debugging structs :) I'll have to take a look at RenderDoc as well hehe

Roger that. But there's a broader understanding to have here I suppose. Using three float2 would be equally troublesome here, I think 🤔 Struct would still be padded to be 16bits aligned.

Noted, thanks!

I'm a bit puzzled. Anyone care to explain what's going on like I'm a 5years old? 🥲What are the best practices to avoid getting owned again in the future? ty :d

At first I tried to add a float pad_ after float3 Location; and float3 Extent; in the HLSL struct but this didn't work. I suspect that's not where the compiler is adding padding to the CPP struct? Adding padding to both structs did work.

FVector3f says its 12bytes/4bytes aligned, FVector4f says its 16/16. I expected the struct size to be 40bytes but it's 48. I suppose the use of a FVector4f forces the whole struct to be 16bytes aligned?

Anyway, I hope you all had great holidays 🥰

Happy new year!! Cheers.

It feels like a nice way to end my UE content creator journey. I kinda started with water, so I'll end with water I guess =)
I'm hoping to do more stuff with interactive foliage before that though

This helped immensely: github.com/2Retr0/Godot...
This as well: github.com/tigershan113...
And that one, ofc: dev.epicgames.com/community/le...

Next:
- Get a better understanding of the many existing FFT GPU/CPU algos
- Cascades
- Foam & velocity
- Splashes
- Copy UE's water quad tree
- GPU Readback
- Get more comfortable with UE's RHI
- Clean code
- Try using UE's FFTGPU
- Make a video about it before end of February :|

I don't know :D

Amazing stuff!

Damn, that's fantastic work! Thanks for sharing. Always a treat to see WIPs of complex systems like this :)

No worries about the wall of text :D sry for the late reply. I'd be curious to know how they did it for PoP as well. It appears UE has all the built-in tools to rewind anims and what not for debugging purposes, so I'm assuming it can be recycled for gameplay as well. I'd have to look at their method

Thanks for the on-going support🥰Next video will be about GoW dual depth foliage interaction technique! And then more VFX/shader stuff :) Cheers!
