LWRP Boat Racing Demo from GDC

Cool, thanks for that info. Regarding HDR vs LDR, do you have a rough idea how much more costly it is using HDR + tonemapping on mobile platforms, vs just using regular LDR with the pp stack v2?

 

@Andre_Mcgrail The terrain shader seems broken, it's all blue

 

reimporting the shader still not fixed it, but i got it fixed by open shader graph and resave it

 

We're still plagued by constant "could not read file" error messages in Unity, but since this has persisted on many imported projects from 2017.x up to 2018.3, perhaps it's a local PC issue in our side (the obvious temporary disabling of OfficeScan did not immediately help). Anyway, 100+ importing errors sadly prevent me from checking this out at the moment. I'll wait until there's a stable release and see if I can sort this out.

The chances of getting this to run in single pass stereo mode in VR is probably slim anyway.

 

Unloading broken assembly Assets/Plugins/Editor/JetBrains/JetBrains.Rider.Unity.Editor.Plugin.Repacked.dll, this assembly can cause crashes in the runtime


Any idea what could cause this?
I used unity 2018.3.b04
with repo 4.0

 

You can safely remove it: it's Rider plugin, it does nothing if you don't have Rider.

 

@Andre_Mcgrail I assume the waterFX distortion that happened on the edge of the screen (like in the screenshot) are the product of screen space displacement isn't?

 

actually i try to do that, but since my SRP knowledge are still very basic i failed .
which bring me to some question if you don't mind.
- is the CameraData are the actual camera that used for rendering the game view?
- is it possible to override the CameraData.Camera setting for rendering the WaterFX pass, or should i create a new camera for that?

 

How to import water and material in HDRP ?

 

@konsic you can't:

 

So what about a decent water solution in HDRP! This has been the most requested and yet forgotten feature even in the normal pipeline for years. Guess the latest water system officially released was in Unity 4!

 

i doubt will get that sooner, until HDRP support custom renderpass at least.
at the moment water solution in HDRP just transparent with panner normal (or flowmap) with distortion pass

 

Hi, any way to make the water shader double side for underwater effect? thanks.

 

That's exactly what I did to create a lake but far from a real water surface, the Refraction Model does not seem to give the depth illusion and I'm not sure if I set the right settings for it, also the Distortion is everywhere including the outer surface itself! Can you share your settings and screenshots to compare?

 

Oh i didn't use refraction, i just don't like how it looks. I use distortion only

Basically it is like this

 

@Reanimate_L That's so cool man, thanks for sharing, just realized I'm definitely not using the distortion properly. Also I never tried ShaderGraph and just used the parameters in the material UI, that would be a great start for me discovering the ShaderGraph

 

@Andre_Mcgrail I'd like to pass on my thanks and congratulations to you and the team for making this beautiful demo.
Good to see its not just the HDRP guys getting all the limelight, can't believe this runs well on a 6S. Looking forward to digging in and looking at all the tricks you used to pull this off.

I'm hoping I can transplant the grab pass refraction into glass objects in my AR experience. I've scoured the internet for good realtime refractions in AR and it seems elusive. But it feels like this might give results that are more than good enough considering the restrictions.

 

it's amazing what could be achieved through LWRP!! Amazing resources to learn form!!

yet i can't hide my disappointment on a sample project that runs 10fps on handheld devices.. even less on mid range devices.
it would be amazing if all these amazing graphics can be run at least at 30fps on mid range devices! isn't this the purpose of LWRP in first place??

 

What handheld device though?

"Handheld device" could be a low budget android phone with barely any power, or it could be an iPhone Latest / Samsung Galaxy Latest which would have tons of power.

Knowing which hardware you tried on would be good, and no it will never run at the same 30fps on all devices, as there are just so many different levels of hardware power out there in the mobile market, some are not very powerful at all.

 

i have tested it on lenovo tablet with adreno 506 (not sure if this considered low end or mid range, around 1 year old device) i got like around 5 fps

i have tried it on pixel 1 with adreno 530 this is considered a highend device almost 1 and half years ago.. when this project is published..and i got like 10 fps..

i noticed that the scene in the project isn't "fully" optimized for mobile in fist place... so i tried disable everything in scene.. and only left a single boat with the sea.. tested it on pixel 1 again and got like around 20fps.. this is less than 30fps on almost an empty scene!

that is why i was wondering what's the point of showcasing "LWRP" in this project..
if it can't run well on devices that are 1 to 2 years old..

 

@mangax they said they are getting near to 60FPS on an iphone 6S
I get the impression it has been mainly tested on recent apple mobiles.

 

No way it can run around 60fps!!
actually in the demo video they stated their target is 30fps on iphone 6... i wonder how is that achieved?

the project scene have so much of top known "performance killers" on mobiles..
a post-processor.. a Terrain .. so many Vertex animated vegetation.. with super heavy sea shader..
have you checked the drawcall counter?? it's hitting around 400+ <-- only PC can handle this

 

Well. . . . what do you know. With enough hacking this technique can be done in HDRP apparently. But yeah. it's a total hack, so it bound to glitch etc
Also the way i'm doing it right now, it might be the least performant way to render water pass in unity :S

 

I have an iphone SE (same as 6/6S) and it runs around 50fps-60fps so I do believe their claims are true

 

mind sharing a small video sample of demo running on your phone??
if it is possible (which i doubt) am interested to know why android version is not getting same performance..

 

nevermind, i tested this on my iphone X not SE, so thats why its running well (£1000+ phone)

 

i see now,,, Anyway you shouldn't post false information which can miss-guide people...

 

I wasnt. I had gotten confused between which work device I was using. We have 20+ phones, Im not going to know off top of my head without looking back at logs which I just did.

Dont try and make it sound like I was purposefully misleading people, theres no need to try and inflame for no reason.

 

I was not able to run it on iPhone 7 FWIW due to runtime shaders errors (using Preview-4.0 branch)
That _might_ be my somehow screwed setup, but this run in the Editor however

 

the whole project was an attempt to optimize everything to achieve 30fps!!
Check their presentation.. this means automatically that the challenge is to get it to work at 30fps at max on iphone 6..

so when you said you got like 50 to 60 fps on SE similar to their claim (which isn't)...let alone 60 on SE..
i was forced to doubt your test!... but i see now you have a lot of phones

thanks for clarification.. i was worried that there might be a gap between iphone and android phones in terms of performance on almost similar spec phones..

 

I think based on what andre has said and our own tests, that the current performance isnt what its meant to be. Certainly we were expecting higher fps too so hopefully by the time the LWRP is out of preview they will work out the exact bottlenecks and address them.

For now though, dont be disheartened, Im sure it will become usable soon for your purposes. That said you could always look into some performance optimisation assets from the asset store in the meantime if you have immediate needs of high FPS on mobile and are struggling.

 

Is there a specific commit that was able to get 30fps on iPhone 6?
Because after numerous optimizations, greatly reducing Quality settings, Graphics Settings, Post Processing etc., I was able to get the fps on OnePlus 5 (High end, Snapdragon 835) to 40fps. I think it won't translate well to iPhone 6 (Would probably get <10fps).

 

Just curious if the bugs were fixed

 

@Andre_Mcgrail just noticed that the Boat Attack github repo is under GPL license. I don't think you can do that though as GPL is a copyleft license and it requires you to relicense all other code your project touches, in this case it would mean also things from Unity's side, including but not limited to LWRP (which you can't relicense).

Most common options on the table for licensing that doesn't clash with Unity's terms would be MIT, BSD, Apache, CC-BY and if you want to prevent others from using this content commercially then pick CC-BY-NC.

Just don't swap to CC-BY-SA as that's also a copyleft license and has the same issues as current GPL license has.

 

Hi in this repo there is an infinite water scene. I kinda understand what it does. Can anyone give me a technical detail of how it actually works.

 

Any chance this water will work on the hdrp?

 

any updates? I've just tried the master branch with unity 2019.1.1 and no luck yet

 

No, using 2019.1.1 it throws errors on console and not able to hit play to test it

 

A whole bunch, but also missing water files. I tried doing a pull and also with a zip download with no luck.

 

errors when loading (it looks for d:\srp which is not on my path)
An error occurred while resolving packages:

A re-import of the project may be required to fix the issue or a manual modification of D:/BoatAttack/Packages/manifest.json file.


then I hit reimport all, so it will redo the manifest file. Same error

 

Then what I had to do was reset absolutely everything on the package manager and redownload (i'm sure there is a better way)
But then when I hit play I get this:

no clue what's that "smash" thing

 

It's Burst and package manager issue. Just restart Unity solves Smash error.
