Workaround for Efficient Outline Effect in UE4 with Instanced Stereo Rendering
I wrote this article after struggling to find any relevant UE4 documentation on the matter, and an extensive googling failed to provide me with the right incantations. So I've recorded my solution here for posterity, niche as it is, in hopes that someone with the same problem comes across this one day. So ride along with me and lets shave this Yak!
You can scroll down directly to the guts of the workaround here.
Context
I recently began work on a personal project in VR for a mobile chipset based headset. I installed the most recent version of Unreal 4 Engine to check out the official VR template project.
The template is a great springboard, especially for configuring all the dials & knobs in project settings for optimal VR rendering, such as setting up forward rendering, instanced stereo, anti aliasing set to MSAA, etc.
The template also comes with a great example implementation of a selection mechanic, an arc that appears from your controller when selecting a new location to teleport to:
For my project, I wanted to implement a new feature for selecting objects: placing an outline around an object. This is a very common effect in games and is sometimes accomplished using a post process. The basic idea is use a stencil buffer (and/or a depth buffer. I am going to refer to a stencil buffer for simplicity.), and in your outline material, you consider all the neighboring pixels of the stencil buffer, and if the current pixel is on the boundary of a stencil value change, then draw an outline there.
On a mobile chipset such as the Oculus Quest however, post processes are prohibitively expensive, because reading and writing out buffers the size of the entire viewport is a slow operation on that hardware.
Local Outlining
Tom Looman provides an excellent strategy to achieve a post proces effect like outlining while avoiding a full screen post process: use translucent meshes that locally surround an opaque object you wish to outline. The translucent object's material is where the outlining effect lives, so the outline is only calculated on the pixels of the viewport that the translucent mesh occupies. It also eliminates the need for adding an entire post process pass for the effect, because within the UE4 forward renderer, translucent objects are drawn in a pass after the opaque objects.
Trouble
So I paid a small fee to Tom’s Gumroad account to access an example implementation of this idea provided on his blog. The effect is well illustrated and easy to demonstrate in the project. However, it was really just a sketch of an idea, and not intended for specialized contexts like VR. Which, is totally fair.
Needless to say, I ran into some issues when attempting to use it in my VR project. For one, the effect is broken when using the VR template default of forward renderer with MSAA. And additionally, the outline appears in only one eye when the VR template default Instanced Stereo Rendering is enabled.
Bummer! Forward renderer & MSAA, & ISR is a really powerful set of rendering features I wanted to take advantage of on my VR project. I want to stick with forward because I am targeting mobile chipsets, so I’ll switch to FXAA for now. What about ISR? I can probably live without that, since I don’t know whether it will pay off for me yet: ISR helps you if you are CPU-bound. However, I had some time to look into it, and it just bugged me because It Should Work, so I dug a little bit and wanted to share what I found for posterity.
Workaround for Sampling Custom Depth & Stencil Correctly in ISR
The problem occurs when sampling into a stencil buffer to find boundaries on the stencil for our outline effect. We sample the stencil using screen space UV coordinates for the pixel currently being shaded.
However, when ISR is active, and the second eye, the right eye is being shaded, the screen space UV coordinates returned by the built in Screen Position material node give you incorrect results. To get correct results, you need to scale the U value by 0.5.
Additionally, after you’ve scaled the right eye U value by half, you need to sample your stencil or depth texture using an HLSL call. Submitting these coordinates into the built in Scene Texture material node does not give correct results. So you must perform the sample using a Custom material node with the HLSL:
return SceneTextureLookup(scaledUVs, 25, false);
13 and 25 are the hard-coded numbers for accessing custom depth and custom stencil buffers within UE4 HLSL, respectively. The false is just for disabling bilinear filtering.
This feels like a bug to me. Certainly not the desired behavior from my point of view as a user. Something is wrong with how the Screen Position and/or Scene Texture material nodes are handling the use case of Forward & ISR.
But there you have it. Here is a quick sketch of a material function that returns a sample from the custom stencil buffer and gives correct result whether you have ISR on or not. ISR is considered "off" by the shader system when the viewport is monocular, or if the viewport is stereo AND the left eye is being shaded. In other words if you query the ISR state in HLSL, it returns true only when the right eye is being shaded. This can be queried via return IsInstancedStereo(); HLSL call.
Note: For any picture of a node graph below, click image for larger res with more node visible
So basically anywhere that the original material is sampling custom depth or custom stencil, you'd use these material functions instead.
Disclaimer: I am not a tech art whiz so there may be a more efficient way to express this, but you get the idea.
Here's a beautiful image of a stereo pair rendered with ISR enabled and the outline effect in action!
And finally, here is a giant code block of the above material graph nodes I copied out of a vanilla UE4 version 4.27 project if you want to paste it in quickly:
