Unreal Engine – Soft Glow Outline UE5554

Performance

At at resolution of 1920×1080 on a NVIDIA GTX 980 (released in 2014) it only takes 0.3ms at 100% and 0.16ms at 75% resolution scaling, to render the outline effect on medium quality setting and 8 pixels in size.

You can also see approximate performance numbers for different settings in this video.

Scalability

In the default AutoQuality mode, which seeks to optimize sample counts at different outline sizes, the effect offers a quality parameter, which allows you to choose the quality/ performance trade-off that works best for you. If you need more fine control, you can disable AutoQuality mode and set the sample counts manually.

In addition to that, the performance cost scales very well with resolution scaling and the cost of using multiple outline styles at the same time stacks linearly.

Rendering Compatibility

While the effect was designed to work best with TAA, it does have automatic fallback solutions for FXAA, MSAA and no anti aliasing built in – look at the video/ screenshots to see what it looks like at different quality settings with different anti aliasing methods. The effect also automatically adjust to any screen resolution or resolution scaling.

Included Content

This product includes the Soft Outline master material and 20 material instances, each featuring a unique style.
