IS URP mobile production ready?

Hi there,

Im going to start a new project that ill be launching with Unity 2019.3/4 and want to know if URP is production ready for mobile? Is any one actually used it to deliver mobile games? My game is purely UGUI driven as its a 2D Game.

Please advise
Thanks

 

Not yet in my opinion, but if you are okay with fighting with it a bit, then it should be fine.

If you do switch, make sure you research which features are / are not supported... for example SpeedTree is meant to be supported but it’s completely broken & they won’t acknowledge it, I understand it might not be priority for them, but you will run into various smaller things similar to this that will take forever to get fixed & can interfere with development.

 

I also wont recommend it, maybe 1 or 2 years later when post fx, camera stacking, frame debugger, vulkan api and others get more stable.

Also, there is many topics about crash using iOS certificates.

I'm using URP in production on mobile. I'm yet to release my game but it should be out in about a month. it'll be interesting to see how stable the build is in the wild vs my other games that don't use URP.

 

From my experience (Im use HDRP/URP/LWRP since release) now its pretty stable and sometime better that built-in render pipeline (in performance case case). And right now i'm porting few big games to HDRP and URP almost without problems. Glad that developers of HDRP/URP do bug fixes pretty fast ( update 1-2 time per month ).
So I can say that its production ready, but still you will have to fight with few problems.

 

We just finished a major project tailored to run on iPad Pro (iOS) and URP behaved pretty well this time. We had a similar project a year ago and tried to do it with LWRP but had to revert back to Standard because LWRP wasn't there for mobile yet but I feel URP is good to go.

 

Thank you all for your reply.

Please do note that i'm making a pure 2D game using uGUI Canvas. There is nothing 3D in it.
But i want to use URP for performance reasons.

 

Thanks!! Happy for this to be acknowledged. You can find more details here including someone who already made a bug report.

**The bug report description isn’t accurate, there seems to be quite a few issues with the shaders in general, I’ll quickly outline the ones I saw.
1. Double sided geometry has flipped normals which is not always wanted, an option for this would be sweet, as SpeedTree has an option for this in their editor.( I also think not flipping normals on backsides is more performant, not sure though)
2. Trees do not receive ambient light
3. Billboards do not render their direction correctly, or receive ambient light.

 

Thank you so much, really appreciate this!!

 

Hey, sorry to pry, is there any sort of ETA for this?

All the best

 

Can you also ask for an update on supporting wacom pen pressure on the terrain painting operarions by default?

 

Oh, terrain team will do URP simple Terrain material that will use diffuse + normals only with simple blending? Cuz right now terrain material in URP non optimized and has wrong render queue (From far to close, but should be from close to far).
In standart render pipeline you has terrain(pc) and diffuse terrain shaders( mobile).

That would be great for mobile and Oculus Quest VR

 

@Elvar_Orn
Can you please also ask Terrain team about getting back the "Target Strength" of terrain brush? It's vital for managing height blending.

If you need more details, please forward them this forum thread:

Thanks, What is the difference between build in terrain and the new painting system?

If I can do all the painting in the new painting system and export the results the built-in terrain, thats also good.
If not then I would like to request it to be added to the standard terrain.

 

Great Thanks

 

Tried to convert 2 projects to URP, and performance on mobile was horrible.
It's horrible even on an empty project.

 

Speaking of terrain stuff, the default URP terrain shader renders way to bright on iOS with incorrect lighting.

 

I have been turning off the SRP batcher on iOS, with it on my cpu usage spikes to over 20ms "wait for target FPS" (even though VSync, etc is disabled, & FPS is capped at 60) and with SRP batcher off my CPU usage stays steady at 16.7 over any period of time.

 

I've replied in another thread, but I'll mention this here as well: https://forum.unity.com/threads/per...ions-of-unity-post-processing-and-srp.786944/
This thread has several replies from developers and can shed some lights on current state of URP performance and what to expect in the near future.

 

Is it better to hold off on URP? A couple of posts floating around that making me really nervous switching my project over. I don’t mind waiting but I don’t have the bandwidth to debug lower level issues.

 

i would say if your project is going fine and you don’t need any features from URP then there’s no need to switch.

i only chose URP because I started a new project with it but i still wouldn’t update any old projects to it.

i will add that eventually i will update older projects to it as it has improved a lot but like you I’m a solo dev and don’t have the bandwidth to figure out new solutions to old problems at this time

 

I don't think terrain ever is a good idea for Quest. Because it touches on too many intermediate buffers and Quest is just too strapped for that kind of stuff. If you can dodge it by using great mesh pieces that lod, you really should. 4 splats is also just not sane for Quest. It's fine for a mobile title but a mobile title isn't required to achieve 1440 × 1600 per eye at 72 frames per second without fail. A mobile title is fine at 30 frames per second (regardless of mobile hardware in Quest).

Sure, you can do it, but you would sacrifice a lot of perf you can use for other things.


I think URP is ready for mobile dev 100% but I'm not sure it is stable for VR yet. I would for sure develop with it for VR (I am) but only if release is a ways off.

 

@Elvar_Orn
An important question :
Do the bug fixes in the latest version of URP apply to previous versions as well? For example, I want to use the unity 2019.4 LTS , which finally supports URP 7.5 . Will the bugs fixed in URP 10 also apply to URP 7.5?

 

need to see in issue tracker is that bug was backported to your version

 

According to the old tradition, new versions of Unity include two features, one is new features and the other is fixed bugs, which are also applied in previous versions. It is now expected that the bags fixed in the new version of URP will also apply for Unity 2019.4 at least . because they said that URP was including in unity 2019.4 LTS

 

Is URP ready now ( may, 2021).. he-he? Do it work normal on old phones(Samsung A20-A10-A30)?

 

Download my game and see, it’s made with URP.

I was reading this post like 7 months ago when I was trying to decide on urp so I thought I’d give my thoughts. I’m using latest 2020 LTS URP Render for Jonk, Inc. Runs on anything that has at least OpenGL ES 3 that handles linear color correctly. This is basically everything after 2016.

FYI for anyone new to mobile dev…google is moving to 100% arm64 native and api 28 or Android 9 for any new updates or releases on google play. Apple is already there and require arm64 to publish anything and is starting to wash their hands of old devices. It’s pointless to try and make mobile apps run on ancient hardware. New low bar is anything Android 9. Unity has pretty much stopped all dev work on standard renderer. Everything is going into urp for mobile. There are 2-3 year old bugs in standard renderer that aren’t worth fixing. Everything looks amazing on urp out of the box and shader graph is the future. Frame debugger has been working really well for me when trying to squeeze performance out. Haven’t had any stability issues.

 

If you need camera stacking, URP is terrible on Android.

Hi everyone.
Please help me. I'm using URP in Unity for mobile.
When I run app , app was stopped.
What's wrong with this?

 

Look at console output, read errors, fix errors.

We can't really help as we have no information.
