Official 2D Renderer in Universal Render Pipeline in 2019.3

Having separate forum is really cool. Can you fill us about the tilemap support for the shadow casting? When will it be supported? Soft shadow?

 

Hey, cool work on the 2D lights.

I want to highlight a need to cull light better, since it is not being done well and when I generate a larger scene with lights it still goes through all of the lights in the scene that should be frustrum culled or distance culled at the very least. Can take 8ms in a not too big scene. We do our own culling now on everything but it would be nice if it was not needed for the lights.

Also want to mention that there are some iffyness when you want to use meshes and bones that are rotated quirky, the normal map stuff uses the rotation a bit weird since it uses the same functions for 3D normal code. I will see if I can get time to share this at some point.

Would like to take the time and show that we are using it for Source of Madness
Here is a small visual tease.

We use the shape light to highlight the entrance to the shop for example, I also made a special light type for the global light that adds and acts as a sort of ambient fog.

Also we at Carry Castle will be at GDC to speak at the machine learning talk o/

 

Is it possible to have more than one 2D Renderer Camera in the scene for doing funky blitting stuff? It seems that camera stacking isn't supported (will it do so any time soon?) and trying to grab rendertextures from more than one camera isn't allowed at the moment?

 

It is not anything fancy, we spawn a lot of prefab/rooms in a big grid, and now we distance cull grid cells based on openings. However we only need to do that because the lights take too long to render when there exist a lot of them in the active scene even if you are not remotely close to them. I think it got to do with how you do the global light but I need to take a look at it again. Preferably it would be nice with some inbuilt culling for the 2D lights like there are for most featuers and other light types.

The normal map texture you create is affected by rotations that a 2D renderer should not care about so our 2d rendered meshes gets weird artifacts since it is very difficult to import completly clean armature setups into unity. I need to find my documentated images to explain this properly, but in essence we do not get even light distribution on our "2D meshes" because things are rotated and that affects the image you create for the light directions.

The big issue with the normal is when we stack our objects infront of each other and they get vastly different lighting result because of their different transform matrices.

 

I'm getting a lot of inconsistent behavior when trying to add any of the experimental 2D lights to the hierarchy. Sometimes it adds a light, sometimes it doesn't. There are no errors in the console when it doesn't.

Makes me believe there are some rules or conditions that need to be met that are unclear and uncommunicated.

Using 2019.3.2f1 with URP package 7.2.1

Likewise, when I do get a PointLight added to the hierarchy, adding the Light 2D script gives me a warning which I do not agree with since I'm using the 2D renderer data with URP and everything is assigned in the inspector



Nuking the default assetPipelines that come with the template seems to clean up the situation. So I'm guessing there's some references that are not being reset when starting a fresh project from a template

 

Here you can see the funkyness of the normal map/light render. Snippet taken from a gpu profiling when it "renders" the normal map/lighting map

 

I followed every step, but I'm not able to add any 2D light to the scene...

 

By template, I mean starting a new URP project, ala...


The issue is with both 7.1.8 and 7.2.1, although this time I saw an error in the console. The first gif shows not being able to add a 2d light.



The second gif shows it working AFTER deleting the default pipeline assets.

 

@Chris_Chu Thank you for responding!

I did assign it...

 

@Livealot, I didn't read your previous comment at first, but it solved my problem too! thanks!
Is deleting those files something we want to do, though?

 

Is there any plans on supporting SpriteRenderer's Flip X with normalmaps?

 

Hello! I'm getting garbage generated every frame by the RenderPipelineManager.DoRenderLoop_Internal() call. Closer inspection suggests RenderingUtils.RenderObjectsWithError() is what's allocating the memory, specifically Material.CreateWithShader() further in.

Any idea what might be causing this to happen? RenderObjectsWithError sounds like something I've set up might be causing this?

 

That's a very good question. I've been wondering this myself also.

 

Thanks! What kind of thing would cause RenderObjectsWithError to call? Anything using the legacy Sprite shader? (Edit: It seems like that's just called with every camera rendering pass, so not ideal that it's just naturally making 0.4kb of GC Alloc every frame.

I have a couple of extra cameras in the scene (doing some reflection-based rendering shenanigans) that are calling GetCameras() and SortCameras() that's also creating garbage every frame with Array.Sort(). I know it's not much, but the only memory alloc happening every frame in my scenes at the moment is coming from the Universal Render Pipeline and that seems not so good

Edit 2: I did a deep profile of the Lost Crypt demo and interestingly I'm not seeing the GetCameras/SortCameras call making a GC Alloc call there, even though that's pretty much where I cribbed the reflection rendering from, haha! I wonder what I'm doing differently that would cause those functions to behave differently for me?

Edit 3: Ok! It seems that having one camera rendering and one camera going to a rendertexture creates zero GC Alloc calls, however having three cameras (one rendering, two going to rendertextures) or more is what starts getting Array.Sort(cameras, new CameraDataComparer()); called every frame. Hopefully something simple that can be fixed if you're able to look at this as well!

 

URP 7.2.1 still not fixed

 

I was wondering if are there any roadmap or version target that we should expect it to be use for at least more than experimental reasons?

 

This seems quite bad news. For my opinion, shadows are weakest part currently (other than your list ofcourse). So we can easily say it's targeted after 2019 LTS?

 

Does anyone else have a problem with a pixel perfect camera, that it 'zooms out' randomly?

I use pixel perfect camera (experimental) from URP and also Cinemachine and I have set reference resolution to 640x360 (with no any other options checked), and when testing with phone (android), it starts with correct resolution, but quite quickly zooms out.

I also tried with upscale render texture checked, but it didn't change anything.

I'm using Unity 2020.1.0b2 and latest URP packages and it doesn't happen in editor. Is there way to 'lock' zoom level or something?

 

I recently started having this issue on PC builds for windows. Got so annoying I took out pixel perfect camera till we find out why it is doing it.

 

When would I add a similar sprite depth of field effect?

 

Hi, I am doing a pixel art card-based game. I am using the new Unity 2D lights. I have a ScriptableObject for the card's data but I can't swap the light cookie from the unity "2Dlight" script because of its read-only. Any advice?
I am using the light cookie to display the image of the creature and do highlights.
is there a way of editing the Unity Script?

 

Hello all,

I'm working on a 2D game for WebGL and was wondering if this package fully works on this platform.
I've been playing with point lights and shadow caster, and they do not seem to work properly.
The same scene in the editor:

and in WebGL:



Seems like the normal map is working but was wondering about shadow. In particular, the casting lightsource is a point light.

Thanks in advance,
Diogo

 

I'd really like to see this prioritized - I've seen dozens of other people asking for it since 2D renderer was first publicly available, and in my opinion this is far more important than shadows in 2d atm. As it is, high quality, professional games made with 2D renderer are essentially restricted to pixel art games - not having z-write on the sprite shader removes a lot of options like water, depth of field, etc. Even Ori, the game that has been the face of Unity's website for the longest time and still tops the "Made with Unity" chart, is quite literally impossible to recreate with 2D renderer atm, not because of performance issues, shadows or the other aforementioned things, but not being able to have depth based effects.

 

On another note, I've found it really handy to create "manual" shadows using the 2D lights using a custom subtractive blend style from the 2D pipeline asset, I think including a proper shadow/inverse-light blend style for the 2D pipeline would be an amazing addition, as it gives us complete artistic control over how the shadows look in a scene!

 

Will there be a custom falloff distance for shadows aside from Shadow Intensity setting in lights?

 

There's no need for that.
I ended up raising the default quality settings to Ultra in WebGL and it started to work.

Thanks for the reply anyway.

 

Hello, is there a way to use the 2D Renderer with a scriptable render pass and a graphics command buffer? I'd like to try and draw something additional orthographically in screen space - similar to URP's 3D RenderPasses by just grabbing a commandbuffer and drawing a mesh in the Execute(ScriptableRenderContext ctx, renderingData) function.

 

Actually I was able to figure it out by just switching the inspector to be on Debug view instead. By any chance will this field be exposed in the future?

 

was also wondering about camera stacking for 2drenderer. any eta on this?

 

Also, I was wonder how to add emissions to the shader, using shader Graph? The Sprite Lit Master node only has 3 inputs... Adding to the color is not the correct way. We need to be able to add colors after the lighting.

 

Hey again,

I'm trying to use shader graph to create a custom shader for a material on URP.
I was wondering if I can use the computed lighting anyway?

Maybe these variables also apply for the 2d Lights. Is that so?

Thanks
