LWRP Boat Racing Demo from GDC

I'm glad you liked the demo, looking to make the Git repo public asap but the crunch of 2018.1 release has kept me very busy so my ability to work on cleaning this up has come to a standstill right now. Hopefully won't be long off, maybe next month but don't quote me on that

 

Haha, So I'm am busily working on it right now, we are going to be demoing it at Unite Berlin and @phil_lira and I will be giving a talk about getting started with LWRP.

The aim is then to clean the project up for a first release alongside 2018.2.

And trust me the wait is worth it, it's already much better than a month ago, running faster and the code is getting much cleaner(which will make it more valuable to learn from/dig around in)

 

Hi,

Sorry for not responding about this and missing the date I first suggested.

A little insight to this since I think a lot of people are missing what this project actually is. This demo is created entirely by myself, this wasn't part of my day job here at unity, I'm not on any of the demo/content teams we have so a lot of this was/is done in my spare time.
With LWRP being in the state it is and our major push now to stabilise it, this is now taking up all of my time as I am busy making sure we have proper coverage of everything and that we start to actually have documentation on it as releasing a demo is useful to learn how to do some specific stuff but without any documentation making sense of anything in that demo, it will probably be just as hard as diving into the code without a demo.

In saying this, I'm at a point where I just need to make the git public, I'm planning on merging in a submodule to make life easier for people grabbing it(no need to clone if you just want to grab the zip) and also making it work with the packages available rather than cloned git repos. One huge issue I am facing with it right now is the delayed 18.3 Beta which is frustrating as I converted some of the water rendering over to the much better custom pass rendering system that we have recently added into LWRP, this package now is only available in 18.3 so this leaves me in a tricky situation.

So I can make it public right now and everyone will have access to it, will it work, I'm not sure, I don't have time to test it in 2018.2 right now(the preview nature of LWRP means we move on pretty fast internally), but in theory it would work, again this is not an official Unity demo project thus support for it will be limited, and at the end of the day it's a test project to help me verify certain parts of LWRP are working correctly.

Again sorry for not responding here earlier, life has just been a little hectic here lately

Cheers,
Andre

P.S. I'll distract you with this if you didn't see it at Unite, because you know, chairs and all....

 

It is still planned to come out this month, but I do feel like this has been the most delayed Beta we have had in a while normally we are pretty good at getting it out the door as we release the previous version, this time it wasn't the case.

 

Hi All,

Just a brief update, I have managed to get some time on this, it's now fairly clean and also contains no submodules so it will be much easier to grab/update etc. One issue though is it currently only works in 2018.3, which as many of you probably know has been delayed, unfortunately I heard it has been delayed again so right now releasing this would be pointless as it would have compile errors and not work, these are due to Area Light and the NavMeshComponents having an API breaking change between 2018.2 and 2018.3, since this project is mainly used as a testing/inhouse project for use with the latest master branch of SRP and 2018.3 I'm not going to make an 18.2 version.

But it is close

 

There is no official word on it, nor do I believe there is an official date or anything. I'm just letting you know here, probably not allowed to, but I think people know it's been delayed as normally we ship a beta a week after a release.

I won't go into details as to why, but it makes sense, and trust me in the end it will be worth it.

 

Hey all,

I've made the Github repo public now, the default branch atm is Packages/3.3.0 as we have yet to release a newer package of LWRP, the Master branch should always work with master of SRP repo if you want to stay on the latest.

The main scene is the Island, in here you can play and the boats will automatically try race around, if you hit 'H' it brings up the camera controls and some performance stats.

https://github.com/Verasl/BoatAttack

Hope you guys find something useful in there, especially look at the PlanarReflections.cs and the WaterFX.cs for usages of the new render pass system in LWRP, I'll be adding another one to render a mini map of the race track as I believe that is another good use case where people tend to use a second camera which is not needed.

 

Would love to see those errors as it should work with latest beta.

Unfortunately the WaterFX pass is using the scriptable pass system, which currently only supported in LWRP, I'm not sure what HDRPs plan is for pipeline customisation is at this point but can ask. As for the water resources missing, I have run into this before and it is due to the WaterSystem being a local package, you can manually assign it back to the water script if you want to get it working, but I do need to look into this, unfortunately this might be out of my hands for now and may require updates to the package system.

 

Yes it is much more complex than LWRP, that's why I like LWRP more for having a play with rendering and SRP. You don't have to be an insanely awesome graphics programmer to understand it.

I've pushed an update to the repo which now has the Scriptable Objects assigned as defaults to the Water.cs, not sure if this will help or not.

 

Next year we plan to start work on a Deferred path for LWRP, we are currently in the conceptual phase and have a very very barebones version running, but we are looking into doing some really cools stuff there, you should start seeing stuff in the first half of next year.

I'm not very good at French but the PackedPBR is a Shadergraph shader, so I would try reimport the shader and see if that helps.

 

It almost did back at Unite Berlin this year, and easily did on an iPhone 6s, I've yet added some stuff, also the pipeline has gone through a ton of changes, so this may push it either way.
I haven't don't much profiling on it lately but I believe it's gone down a bit as I've added more stuff to it but I'm constantly seeing whats slowing it down and tweaking things, either on my side or letting the devs know something LWRP side is slower.

The whole thing isn't HDR, the camera is not rendering to an HDR buffer so doing HDR colour correction would be overkill. I went with this option to save on bandwidth and less complex calculations in post, this does mean I loose a bit of visual quality, there are some points in the demo that get blown out too much due to me trying to achieve a 'HDR' look with the lighting.
I do want to create a branch at some point where it is setup as HDR to see what the performance differences are, but there is still a lot left to clean up so will wait for it to be in a nicer state before branching it again.
