Description

Describe the bug

In the photo you can see a sink and a faucet on the sink, which, in theory and according to the reference (look at the "expected behavior") should cast a shadow, but NRC is not able to process this quickly and keep it in its cache

Image
How do you reproduce the bug?
  1. Download Garry's Mod and launcher from CR and Xenthio (https://github.com/Xenthio/RTXLauncher/releases/tag/v1.0.13)
  2. Half-Life 2 must be installed on your computer
  3. Select map "d2_coast_05"
Image
  1. Disable bots in the context menu (button "C")
Image
  1. Get to this house
Image
  1. The windows should be broken (as in the photo), as it will be dark with them
Image
What is the expected behavior?

NRC should look roughly the same as ReSTIR GI, as well as the reference

ReSTIR GI:

Version

1.1.0

Research direction

Reproduce the issue on map d2_coast_05 using RTX Remix 1.1.0, then compare NRC output with ReSTIR GI and the 1024-frame reference at the described house. Investigate the direct-sky illumination and shadow-cache behavior; done means the sink and faucet shadows retain detail comparable to the references.
