# ThreatInteractive/Prototype-SWRT-Hard-Shadows-For-UE5.7

> A prototype plugin for Unreal Engine 5.7: a spot light whose shadows are ray traced in a plain compute shader, with no hardware DXR. One hard shadow ray per lit pixel is traced against a two-level BVH built from the light's own shadow casters.

## Useful for

- Build a project with the plugin and place an SWRT Spot Light to compare shadows against an engine spot light
- Enable r.SWRTSpotLight.Debug to measure BVH node visits and lane waste per frame
- Study the compute-shader shadow tracing implementation as a base for a custom non-DXR plugin

## Why it’s here

- Star-counter measurements on 2026-10-07 (UTC), 00:20–03:06: 57 → 58 stars (+1). This is the change over that interval.
- Estimated end-of-day forecast: about +45 stars, using observed gains and the previous day.
- The repository is 2 days old and already has 58 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.
- Top new repositories this week: #196.
- About 10 forks a day — people are taking the code.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 5
- Issues and pull requests: 0
- Watchers: 2
- Average over the last week: 34 per day
- Usual pace: too little history (under two weeks)
- Stars in the last hour (measured): 0

## Stars per day, last 4 days (oldest → newest, today is partial)

2026-10-04 … 2026-10-07: 0, 0, 58, 1

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
