LWRP Boat Racing Demo from GDC

ok so finally loaded without errors, but the water looks very different from the demo (very white).
Also, I tried for android but it is set for opengl 3.1. Is there a way to lower the requirements for opengl 3 at least? (and it would be gold if possible for opengl 2.0 since 22% of devices still run on that)

 

Hi, Andre. Thank you for your great work. But it seems not work properly on my PC. I open this project with Unity 2019.1.1f1 and load the Island scene. The water appearance is quite different from the demo video. Here is a sceenshot:


More foam is generated in the scene. Any idea about this issue? Thank you.

Edited: The issue is fixed by restart the Editor.

 

Hi Andre, thank you for your impressive work. I am amazed by the performance showcased in this demo, reflections even on my low spec laptop is a premiere. Waveracer reminiscences are a sweet bonus too !

I try to play with the WaterCaustics shadergraph to tame or disable the effect. My boat is often covered with caustics even if not submerged.
WaterLevel and BlendDistance properties looked promising but I don't see any effect nor find the place where these defaults are overwriten...

If someone could help, I promise to improve my frenglish
Thanks you

 

This is beautiful, but I can't get it to work in VR. Anyone knows how to return to simpler times, when VR in Unity was simply two cameras and not this multipass/singlepass mumbo jumbo? Both LWRP and HDRP fail in VR after months of work...

 

Hi. I've tried building for Quest. managed to get it all except the water .....I dont see the water at all... tried different settings but dont know why... all the rest is running in good speeds ... any pointers? Tnx

 

Unity 2019.1.7...

 

hi i use book of death and i want import only water can help plz

 

Hi Andre, thank you for your help with LWRP issues.

I check the way to get depth from camera and seems there is a ray casting involved in shader. Is this the only way to get the depth from 2ond camera, or there is some new way in latest version of LWRP ?

Also if there is no other way, can we use the following code to do the depth texture for an asset store asset (it is under non commercial license, so by default is not permitted)

Thank you for any insight on the above

 

Hi!

I am getting the following error while trying to build latest Boat Attack 2019.3 version to iOS (Iphone X).
I am using Unity 2019.3.0a11 and Universal RP 7.0.0. Any suggestion how to resolve? Thanks!

 

This demo looks great but it's not optimized at all
It's runs at like 7-8 FPS without shadow, Bloom and MSAA on Adreno 512 which is not a high end mobile GPU but I was expecting a least 15FPS and the water have some rendering issues with the depth (I think) which make it disappear if you look from some angles but only if you run it with OpenGL, with Vulkan everything look exactly like in the editor
I did the test with 2019.1 and 2019.2

 

I would also like to see the water system running on the Quest!

 

I would like to run infinite water shader in HDRP.
https://github.com/Verasl/BoatAttac...asl.water-system/Shaders/InfiniteWater.shader

I there a simple way to convert LWRP shader into HDRP?

 

does it even run on LWRP now? I think it stopped working a while ago.

 

it's still run on LWRP/URP

 

shaders can not perform any raycasting. what do you mean?

 

i got the pink shader. i have updated all dependencies via package manager and still no luck. using unity 2019.3.0 f3. What might me the problem? the graphics setting is using lightweight render pipeline.

 

i wonder how the water fared in oculus quest....

 

Worth asking about it on this thread, me and some other users were critiquing them for saying it works on all platforms when it actually doesn't. A very interesting breakdown of what had to happen to get the demo sort of working here

also it looks to me that planar reflection as well as depth is not supported in quest, because none of this functions i created in shader does not work at all

 

It doesn't work on regular desktop VR, let alone a Quest. I guess we have to wait.

 

I was curious about this so I've done some digging that you might find helpful. I also have an Adreno 530 in my Pixel 1 and like you, I get between 5 - 12 FPS when building to my phone. However, I don't think you're quite right about the reason. Yes, there are a fair few number of batches but this isn't the cause of the tanked FPS.

When I clone the repo and switch build targets to Android the first thing that stands out is that it's set to prioritise the Vulkan graphics API. The Adreno 530 supports Vulkan but oh boy is it a dogs breakfast of a driver. Like you, if I disable almost everything in the scene, I still only get between 5-10 fps.

If I remove Vulkan and set it to only use OpenGLES3, I get between 45 to 55 FPS in an untouched repo of the Boat Attack demo. That's with everything in the scene. However, unfortunately, this totally breaks the water, which is a huge shame because for me the two things I wanted to look at in this demo were the water shaders and the jobs-based buoyancy physics.

I'm afraid I don't know enough about the low level stuff going on in the difference between Vulkan, OpenGLES3 and the Adreno 530 implementation of both to understand why this breaks the water shader so badly but I guess to summarize... this demo CAN run well on mobile out of the box but it won't run well on every device.

Maybe @Andre_Mcgrail could point in the right direction? What is it about the shader that's breaking on OpenGLES3 do you think?

I've looked at various bug reports to Unity on the Adreno 530 Vulkan performance and they've all said 'Won't Fix' because it's a GC driver issue and not something Unity can do anything about. It would be really nice to be able to run these water shaders using OpenGLES3. It's actually the first time I've ever seen a major difference between versions in Unity shaders like this.

 

How to make the water working in VR (Oculus Go)?
