ceto's Issues

How do you select the ocean mesh?

Sorry, I am confused. When I hit play, the Ocean plane is visible, but I cannot click on it in Scene view nor can I select it in the hierarchy anywhere.
I'm used to water being a Plane Mesh that is selectable in hierarchy.
How can I select Ceto Ocean water mesh in hierarchy?

You're a gift

Scrawk, you're amazing, all of your projects are inspiring and actually useful, built for scale and broad use cases. A gem is what you are. Thanks for providing your energy to make the Unity community a better place :)

Learning the algorithm

I was wondering if you had useful links to learn and understand the FFT algorithm?

I only partially understand it so far. I've baked my H0k and H0minusk conjugate functions to get displacement of h(k,t).

But when i was reading the code to generate the butterfly texture, and the actual FFT algorithm the code is hard to understand, not sure what "blocks" are suppose to represent ( i assumed stages (log(n)/log(2)) but that didn't seem to make sense either, i also tried to figure out whats going on even when i wrote it out on paper following the numbers for N = 4 to see if i understood it but it was confusing.

I originally followed Keith Lantz article on it, he goes as far as showing the math proof of the symmetry but then just dumps the code with no explanation of whats going on - plus its hard to read since i don't really know C++ too well.

If you know any links that may help - would appreciate it as i am struggling to decode it from reading the files.

Please provide a 5.6 unityasset file

Doesn't work on 5.6 as prefabs etc are compiled on a later version.

Caustics won't work in opaque mode

Caustics don't seem to work for the opaque mode, only for transparent mode.

All prefabs in demo scene are shown as "Missing prefab"

Git clone of master. Opened in Unity 2018.3.5f1 (ProjectVersion.txt says original Unity version was 2018.3.4f1)

Shadows won't work for transparent mode

Shadows only work on opaque mode, but then caustics won't work due to another issue with transparent mode.

Ceto Wave Spectrum GPU Buffer Error

Hello
I am using Unity v2019.1.1f, when i open the demo scene i am getting this error:
Please can we solve this ?
thank you

CETO Ocean shows sun reflection across the water, even if sun is occluded behind a big terrain

Is there a way to have the light reflection of the sun across the water be blocked and not rendered, if the sun light source itself is behind an object, such as a big terrain?

Render targets issue on iOS devices

I am trying to integrate this project into my iOS game. When I run the build on iOS devices, I get the following crash log:

Devices on which the build crashes: iPad Air (1st gen - A7 chipset), iPhone 6s (A9 chipset), iPhone 7 Plus (A10 Fusion)

Device on which the build runs properly: iPhone X (A11 Bionic)

Unity version: 2019.2.16f1

I have the following questions:

Is this a limitation of CETO water system?
If no, how can I modify the code to make it run on the majority of the iOS devices?

I would appreciate any suggestions and thoughts on this topic. Thank you.

Anyone got this working on windows yet?

I've tried with a few versions of Unity, including 2019.1 but all of them appear to either not want to upgrade the project or unlink all scripts and show some sort of unity_csc.bat cannot be found error, in solution to which I can only find 3 forum threads filled with woodoo magic solutions that make no sense and have even less of an effect.

I've tried it importing as a library as well, which was a bit more successful and only unlinked all 160 scripts, but started to also show... line ending warnings? From that I can only assume this was made and tested on Linux. Should I try pulling with git and set it to convert file endings to windows?

HDRP Support

This shader is really high quality and fidelity! I really enjoy this asset, it's well made! Because it's geared towards high fidelity graphics, could you support HDRP? That would be absolutely insane! Thanks!
