# render.hd.black_frame

> Talos 0.7 · Since 0.7

an HD frame read back for `--record`, `--out` or a capture came out black (the mean of its colour channels at most 5/255), once per run; `record.json` counts them in `blackFrames`. Usually a closed mesh around the camera: its ray-traced shadows block every light outside it, and GI replaces the flat ambient with what bounces inside

## Meaning

an HD frame read back for `--record`, `--out` or a capture came out black (the mean of its colour channels at most 5/255), once per run; `record.json` counts them in `blackFrames`. Usually a closed mesh around the camera: its ray-traced shadows block every light outside it, and GI replaces the flat ambient with what bounces inside

## Fix

give the enclosing mesh a material file with `"castShadows": false`, open it, or light its inside; `render.quality` overrides `rayTracing.shadows` / `rayTracing.gi` false tell which effect it is
