Unite Now Session
Ready to take your game visuals to the next level? Join us for an in-Editor demo of recently released graphics features sure to improve your game. We cover popular tools like Scriptable Render Features for Toon-style Outlines and Camera Stacking for UI.
Together with this Unite Now session we are also hosting a Q&A here in this thread to answer as many of your questions as possible.
A team of product experts from across Unity will be available starting after the session. Our Community team will continue to field questions to foster an ongoing discussion with the community. Please feel free to ask your questions in this thread.
Some basic rules
Don’t bundle multiple unrelated questions in one reply. One question/topic per reply.
Only questions related to the topics of the session are permitted.
All questions will be fielded by our Community Managers (@LeonhardP and @AskCarol)
Replies will have to be approved by the moderators to show up in the thread.
Once approved, the questions will be forwarded to the relevant experts.
We really look forward to hearing from the community. Thank you!
Hey, thank you for the introduction to URP. Learning it myself over the last couple of weeks, it did take some getting used to, since it’s quite different to the built-in RP. So thank you for clearing a few things up!
I do have a question, though, so I can better wrap my head around the intended workflow.
What I’ve been trying to get going is a Bloom PP effect, just using the built in bloom and a global PP volume. This appears to be applied after the AA has gone over the picture, and so there is some noticeable flickering on small emissive object (like start in the sky).
How would I go about so that the bloom is applied before the AA pass happens?
The question was forwarded to the right experts. We are just awaiting their response but due to time zone differences, they might not have seen your message yet. Sorry for the wait and rest assured, it is coming
Is it possible to check which versions of Android the URP supports?
I tried converting my game to the LWRP back when it first came out but noticed that when running the game on older hardware, the environments were black and nothing was visible. I’m keen to upgrade from Unity 2019.1 to 2019.4 LTS (I’m very keen on using ShaderGraph) but the idea of moving to a newer platform, only for it to make my game unplayable to a number of users, means I’m hesitant to do so.
You mentioned about reflection probe improvements in video and Im curious do you add reflection probe mask so we can choose which reflection apply to which render layers?
An excellent talk from @Andy-Touch as usual. I’d also like to tip my hat to @Andre_Mcgrail and the team for the excellent work that has been done on the boat attack demo and URP and thank you for not only releasing the boat attack demo but also maintaining it.
I’ve been very critical of late with Unity but I have to say I’m very impressed with the progress that is being made with URP.
The final piece of the jigsaw for me personally is deferred rendering so its nice to see that is coming along in the video. Any idea of an ETA on this?
I’m also pleased to hear that you are looking to release more examples. I hope they also come in the form of a vertical slice because one of many peoples criticisms (me included) has been that Unity does not eat its own dog food, but this for me is a big step in that direction and I would love to see at least one further example of equal quality.
Something else I would like to see is a similar approach being made to HDRP for examples. Possibly even a version of boat attack with two scenarios, one a straight copy of the URP version but correctly setup in HDRP so we can compare and another HDRP version with all the bells and whistles.
I’d also like to see an upgrade path from URP to HDRP in a similar way that you have going from built-in to URP/HDRP.
Do you have a screenshot or video of the flickering that we could look at? Technically, AA should be applied after the Bloom has been applied so perhaps there is something else happening…
I uploaded a video of this on Reddit. I also noticed that this does not happen when playing a build of my game. It appears only in the editor / play mode. With it not present in builds it’s not a complete dealbreaker, it’s just very hard to work on the look of the project without being able to see how it will look in the build.
I downloaded the examples. 3DCharacterUI on Nokia 5 produces 6 FPS(i only update to 2019.3.4f1). I was expecting a reference solution, but received something not applicable.
What to use for 3D on a mobile? Built-in or urp? If urp, then where to get performance?
Deferred doesn’t currently have an ETA; id imagine it could be available later in the year.
Yes; they are Vertical Slices. I just finished working on a new 2D Example Project that is a vertical slice and uses Universal RP. It’ll be made available later in the year. And I also started working on a new 3D Example Project, which is also a vertical slice, that im factoring in using some features that we haven’t as much Universal RP example material on (Terrain, VFX Graph with URP, Camera Stacking, etc). Its coming along nicely! I think all future projects going forward will be some kind of Vertical Slice; but also with some more isolated examples as feedback from users is they tend to find smaller projects easier to learn from and lift mechanics/code/shaders into their own projects.
Boat Attack in HDRP would be an interesting project! But thats probably more for the HDRP team to attempt.
One initiative we are working on is a closer alignment and compatibility between Universal RP and HDRP; systems like VFX Graph, Shader Graph, Volumes, Post Processing etc already have overlaps between the two in terms of workflow and compatibility (IE: Shader Graph’s PBR Master Node works with both Render Pipelines).
Sorry for delay in reply; it was the weekend plus public holiday in Denmark! Im back now and with some extra info from our Senior Rendering Artist:
The problem is that the stars will go subpixel, and if they are very bright, and the bloom is set to be very strong, it will flicker/flash whenever the star becomes big enough in screen space to be picked up by the bloom.
You need to make sure the stars are large enough relative to the resolution of the bloom (if the bloom is half res for instance, you need the stars to take at least 2*2 pixels in screen space).
As an expensive workaround, in the quality settings of the URP asset, you could set the render scale at 2x, which will in practice double the res the bloom is operating at (but also massively increase everything else).
Technically, stars shouldn’t bloom in the first place… so I’d be curious to see why you them to bloom.Obviously, if it’s a fantasy game, that’s another story, but the subpixel rule will apply, no matter what, and no amount of MSAA can really solve this.
