    Hey everybody!

    With the 2021.2 release, package samples are coming to URP.
    We want to grow the sample collection as features are added and also want to make sure we include samples for the workflows that you are struggling with.

    If you have any thoughts on what you would like to see in the package samples please reply in the thread.
    Maybe you've been wondering how to do some cool effect in URP or maybe you would like to see some specific API in action. Anything goes!

    Thanks!

    I personally always struggled with effects like ripples on puddle from footsteps or trails on snow etc. where you need to inject some data to the render texture. Would love to see an example of this in URP

    Would love to see an indoor set example.

    Thank you for asking this!

    Personally I'd like to see an example of a procedurally generated environnement: advices on how to handle lighting in such a scene; can we use realtime global illumination? If so, how do we tie precomputed lightmaps together?; are there optimisations to do regarding Light Probes?; is volumetric lighting achievable?; tips & best practices in general would be useful.

    Otherwise, even though that might be too specific, I've always wondered how the custom depth of field effect was made in the remake of Link's Awakening (the blur effect is not two parallels lines, it seems they take the ground height into account).

    Effective batched rendering for low-middle end mobiles (with vulkan support) without static batching
    Best practice how to render i.e. small town from constructor using:
    - gpu instancing
    - srp batcher (and how to use it so it will not exceed mali varyings limit)
    - effective use of texture arrays to lower batches count
    - one batch instancing to render many submeshes of one mesh in different places and material overrides using gpu instancing. Like Static batching but without static batch. This way we can make mesh with submeshes of all city constructor parts and draw all buildings in 1 batch because it uses one mesh, one shader, one material with texture arrays, unique transform per instance and unique material overrides per instance. But how to correctly and effectively do this in URP?
    - how to use TextureArrays for lightmaps to lower batches count
    - how to create good looking visual without lightmaps for low-middle tier mobiles
    - how to create optimal city (location) mesh constructor for all this

    edit: actually it is DrawInstancedIndirect, MultiDrawInstanedIndirect use in Unity for efficient draw many pieces of city constructor

    Just curious. Will you ported Lens Flare Sample from HDRP to URP?:p
    I can't find Lens Flare Sample from URP package, but I found some samples from HDRP package.
    Just tried and found it is compatible to URP.

    @lilacsky824 Yes there will be Lens Flare samples in URP as well. It might not be the exact same presets though as we want to keep the amount of textures (file size) to a minimum.

    TrailEffect.gif
    Hey @Onigiri I took your idea and made this sand trail effect. The sample will come with 21.2. It uses a custom renderer feature and an orthographic camera to render a trail map inside the boundaries of the sand box. Hopefully it's useful for leaning some URP intricacies :)

    definitely some custom post processing stuff with render passes.
    sampling light in shader graph (like the blog post you did a few years ago).

    And sample with a VERY BIG map and baked light there. Something like a castle or undeground or parking with vehicles.

    All Unity have is a small 2x2 meters maps for mobile games.

    I really like the 3D Skybox camera stacking example. Its a good use of the stencil buffer.

    Is it possible to get it to work with transparent objects though?
    As the base camera writes each pixel to the stencil buffer (even the transparent ones) the background will not be rendered behind any transparent objects. E.g. particle quads stamp huge squares out of the background.
    I even tried this kind of setup:

    BaseOpaqueRenderer - write stencil
    BackgroundRenderer - compare stencil
    BaseTransparencyRenderer

    But this way the background is drawn on top of the transparent base objects.
    This also has the downside that all transparent shaders are invisible in scene view now as the MainCamera is not drawing the transparent objects and the scene camera seems to mirror the main camera in this regard.

    Ok the 3 renderer approach actually works for transparent stuff. You just have to make sure to use the same near and far planes as the depth buffer of previous cameras will be interpreted incorrectly otherwise

    Advanced use cases of Graphics.DrawMeshInstancedIndirect / Procedural / Now would be great

    Can all of the URP Package Samples be updated to account for the "New" Input System? It's annoying to open the samples and be met with warnings/errors about the old input system is being used for the scripts used in the examples.

    There should be a an ultra low settings sample (ie: something that will run at 72 fps on the oculus quest 1). Something with no post-processing, shadows, a bit of terrain with no normal textures. It won't look good, but it would be extremely useful for the many folks that complain that URP is slow.

    Unity 3d samples are not too much beautiful

    Something like this can be a good 3d sample for URP:

    531.jpg
    The only difference is the art and not the rendering... Unity needs artistic works

    All artists are using the UE and all programmers are using the Unity

    I recommend that you ask some UE's artists to create a sample for Unity. This don't needs too much money

    Hey @UnityLighting
    The samples are designed to focus on specific features of URP while having as low file size as possible. We definitely want to do beautiful scenes because URP is capable of it, but package samples might not be the place to release them. The new HDRP template was received very well by the community so we are looking into the possibility of URP getting something of that caliber.

    An example of a day-night cycle as explained here.

    Day-night cycles are very popular in games these days and would be nice to have a sample to follow.

    Hey @kurroarashi. Real Time GI with Enlighten has been supported by URP from 2021.2 and would therefore be the recommended workflow for day/night cycles. Would you still be interested in a sample that shows how to do a day/night cycle with Enlighten? Something like this: enlighten.gif

    Hey @spajus could you say a bit more about what you'd want from a sample like that? Maybe some specific effect or use case you'd like to see recreated.

    Oh! I apologize, I wasn't aware of Enlighten being supported. I was under the impression that it was still deprecated. I personally have a basic idea for how one might use enlighten but if you could polish up the said day-night cycle example (maybe using some post-processing, using interpolated lighting etc.), I think it might be very helpful to people (including myself).

    I am. That would be very cool sample to learn for sure. Also all the ideas the guys are writing here are very interesting too for URP

    URP sample "LensFlare(SRP)" is not available in orthographic
    The Flare in the sample works fine in lensflare, but disappears when I make it orthographic.
    Please tell me how to get this to show up!
    Please!

    I did something like this for my pipeline. Perhaps you can develop the idea from my example and make it richer in content. In my case, this weighs 33.3 MB.
