Graphics Hydroform Ocean Renderer [RELEASED]

I am no expert but that sounds like a setting somewhere for the culled/render distance. I used it on a large map 8x8 2km tiles and never had that issue. I dont use it now as its not HDRP compatible.

 

Oh nice, fiddling with clipping plane distance did it. Sorry for the late reply, your response went to a new thread page and I didn't notice. I've been refreshing page 19 for over a week now xD

Anyways, you saved the day, thank you for the help c:

 

lol. It ssoundss crazy when someone says I helped because I don't really have a clue. lol

 

Hydroform gives an error in Unity 2020.2.2
Assets\HydroForm\Scripts\HydroformComponent.cs(12,19): error CS0234: The type or namespace name 'VR' does not exist in the namespace 'UnityEngine' (are you missing an assembly reference?)

 

Thanks for letting me know. I'll take a look at it, but it is probably an easy fix as they just renamed something. Perhaps related to this:

https://forum.unity.com/threads/hydroform-ocean-renderer-released.385545/page-19#post-6142734

You have the latest version of Hydroform I assume?

 

Yes I use the latest version (1.39a)
And it is an easy fix (I just commented out

Code (CSharp):

1. //using UnityEngine.VR;

Since I'm using Unity 2020.2)

But I thought you would like know this and provide a neater solution

 

OK, the quick fix is simply to comment out the line "using UnityEngine.VR;" at the top of HydroformComponent.cs. I'm working on a solution that will work with all Unity versions, hopefully have it up soon...

EDIT - ah you beat me to it haha

 

Here's an idea that came out of the blue you might be interested in trying for those users who are asking for a HDRP and URP version:
The shader graph system in HDRP/URP is pretty cool and so why not jump in there and play around with it and see if you can make a decent water shader using the nodes it has. If successful you can add it as part of a free update or something which should provide those who use URP and HDRP at least something that should shut them up haha.
I know you are an industry professional and so you would probably breeze through it easy.

 

Xix-Interactive, just to let you know, the Asset Store link doesn't seem to work in the first post.
I'm getting the error:
default backend - 404

 

Thank you so much for telling me! Fixed!

 

That is a good suggestion and I may well jump in and do it. There are some things I'd like to support and fix that I just can't accomplish with the standard pipeline, like certain fog and lighting support, that should be possible with the new pipelines. It will take a lot of time though. It's all the testing that burns a lot of time, so many Unity versions, and even within Unity there is forward rendering vs deferred, and then PC vs Mac vs Linux.

 

I'm having a strange problem with Hydroform in Unity 2020.2.6f1 (tested it also with 2020.2.4f1)
If I close an Unity project with a Game Tab active (so not behind the Scene Tab but in front of it or next to it, or on another monitor) and a Hydroform Ocean in the Scene. The next time I try to open the project it hangs on 'Finish Loading Project' for ever.

And I have to kill Unity with the Taskmanager

If I delete the CurrentLayout-default.dwlt file from the Library, the Layout is reset and the Project loads.
Something is going wrong with the initialisation of the shaders I think.
I can send you the project if you want.

 

I'm able to reproduce the issue. Not sure what, if anything I can do about it, seems like a unity problem.

 

Has anyone had any luck rendering this beautiful water in VRPanorama? The water displays correctly in Game mode, but when rendered it turns black. This happens even with all reflections turned off. The manual indicates a solution for the water showing up black in the Troubleshooting section, but no solution seems to be provided there. Using Unity 2019.4.20f1 Standard Render Pipeline.

 

Have you found a solution for this problem ?
Or did you file a bugreport to Unity ?

 

I'm going to dig into it soon, hopefully next week..

 

This sounds like it may have conflict with another asset you are using. Try and disable all other assets and see if it continues to do this. You could also try and disable more features in Hydroform like ShoreFX to see if that changes the behavior.

 

Thanks very much for your timely reply. I have created a scene with just Hydroform and VRPanorama. The water starts to show up in the stereo rendering now, albeit much darker than it does in the Game view. Attaching 2 screenshots. One from Game view, the other showing part of the rendered 360 image. Shore line effects are turned off.

Edit, addendum: Tested a 360 stereo recording with the Unity recorder. There, the Hydroform appears as a flattish polygonal surface with a plain looking color, similar to the skybox. Hope someone can help. Would love this water in 360 videos.

 

Oh it's doing 360 rendering? Hydroform has problems with those, probably because it needs to update the viewing frustum when the camera pans across - the VRPanorama would need to do that, assuming it's doing 3-4 captures, it would need to update the Hydroform script each time it rotated to the next capture position.

 

Good news, I have found the problem and the fix is relatively easy. I'll try and get a new build up with the fix tomorrow.

 

I've been trying to implement this asset with a floating world origin, as approximately outlined here:
http://wiki.unity3d.com/index.php/Floating_Origin

I've looked in to some way of moving the water to a new origin, but can't really find any way to do it-

Any idea on how to fix this?

Thanks

 

Hydroform essentially does this automatically - translates the mesh vertices near the camera every frame. You can only control the water level height.

 

Hi. Great work on this plugin.

There is an issue with the UnderwaterFilter in VR (tested with Unity 2019.4.10f1, both with the legacy "Virtual Reality Supported" mode (both Oculus and OpenVR) and the new XR Management system. It seems the stereo rendering is not computed correctly when we are below the surface of the water. This is particularly visible when leaning the head left and right and looking at the horizon (see image below from the "boxes" scene, which show the left and right images). I'm using the default camera in the "boxes" scene.
This issue is present both in Single Pass and Multi Pass. Any idea?

 

I'm not sure what the issue is there. Unfortunately I'm stuck in Taipei with no access to a VR rig so I can't debug. I'm so sorry I can't support this issue, PM me if you would like a refund.

 

Thanks for the quick reply. You can reproduce the issue without an actual VR rig by using the "Mock HMD" feature. In Unity 2019.4, you can find it in "Player" settings.


With Mock HMD enabled, enter in play mode in one of your demo scene (e.g. boxes in the scene below) and bring the camera below the surface of the water. You will notice the stereo-vision discrepancy between the left and right image (brighter blue line at the horizon on the left image in the screenshot below).

 

Thanks for info on Mock HMD.

Looks like this is not a quick and easy fix. I don't have time right now, but I'll address it if I do a URP version of Hydroform.

 

Which setting controls the transparency of the ocean ?
If I disable 'Enable refraction' I have no transparency at all. But I do want some transparency, only less.

 

Look under ShoreFX/Water Clarity

 

Yes! indeed
(I didn't look that far down )

Thank you

 

Judging from the demo the effect looks great, however it's probably not suited for a top-down game? Considering the effect appears to "circle around the center of the camera", it doesn't look great when there is a high camera looking down upon the water.

Is there a solution for that? I have not purchased yet but certain will if there is

 

Yeah it's probably not best if only viewed from top-down. It would burn some processing time on the waves, which you could mitigate, but still not as efficient as a simple flat plane water.

 

I'm also trying to implement a floating origin scheme to hydroform water, and I've got the water height parameter being offset by the origin shift, which does seem to work.

The problem however is that there is still a visible twitch when the origin moves, because the waves aren't being offset with the origin (in the XZ plane)

Here I'm going through the code, trying to follow the implementation of the water height offset, but it's not clear at all how this is being done.

Is there a way to control the UV displacement of the water somehow? Or rather, what should I be looking for to offset the water field without breaking the whole thing?

I'm not trying to move the water meshes.. That does already follow the camera nicely in worldspace. I'm just trying to offset where the 'waves' are.

Thanks in advance!

Cheers

 

I'm using the XRRig prefab that comes with the XR Legacy Input Helpers Package. And have placed the HydroCamMultiComp on the camera object in this prefab. But it doesn't show the ocean in my VR glasses (Vive)
I also get an error message:
Shader error in 'Hydroform/Brim': undeclared identifier 'sampler_CameraDepthTexture' at Assets/_Tools/HydroForm/Resources/WaterFunc.cginc(594) (on d3d11)

 

And as soon as I turn on Initialize XR, Hydroform ocean disappears even for a 'normal' (non tracked VR) camera



Using Unity 2020.3.20

 

Hmm, I am not sure what could be causing these issues. Are you using the standard pipeline? Does the same scene work without the XR plugin? It may just not be compatible.

 

I use the standard builtin pipeline.
This is the same scene with XR off and XR on:

XR off


XR on

You don't need a VR set test this

 

Yeah it looks like some other people are having similar issues with XR, but I'm not seeing any solutions posted. Maybe try to rebuild your Library.

 

@Xix-Interactive love the asset, thanks for continuing to support it. Was wondering if you think you'll ever have a look at getting planar reflections working in VR? Would be so nice. The reflection is appearing in both eyes, it's just not lined up correctly and rotates oddly with head motion. Seems like it's so close!

 

Unlikely to happen soon, sorry! I'm just basically doing bug fixes for it now if it's broken by a new version or something.

 

Does this asset work with universal render pipeline? If so, how do I configure it so that it will? If it's not too much to ask

 

As far as I know it does not work with URP. I'm sorry I don't know how to configure it to do so, last time I looked it was a non-trivial amount of work.

 

What about HDRP?

 

Same thing, it is a considerable amount of work to port to the other pipelines.
