uh.. you happy with the crunch number ?

Why not just license it? Let it live and make done money at the same time.

Maybe hire more people instead of making employees work 100 hr weeks? Thats insane.

Soft Outlines in Unreal Engine 4

Tom Looman shared a new guide for Unreal Engine 4 users. The artist continues to experiment with outlines inside the engine, trying to recreate effects from Left 4 Dead or CS:GO.

Ever since I first wrote about creating outlines in Unreal Engine 4 I’ve wondered if it was possible to render them as soft outlines instead of harsh binary lines much like you would see in games like Left 4 Dead or CS:GO as seen below.

Recently I did a quick experiment using a modified version of SpiralBlur, a node that’s available in Unreal Engine 4, and is using some custom shader code. Here is the result I got:

Looks pretty good! The effect is a little more expensive than the binary outlines since we do several steps in the SpiralBlur node to get to look decently smooth. Later in this post I will talk about performance. The final image shows an extreme setup with high Distance param so show the fade-off more clearly.
