Reads the color at the single point specified by U / V and outputs it as Sampled Color and Brightness (0.299R + 0.587G + 0.114B). Whereas RTAverage covers the whole screen, this one looks at just the single texel you aim at.
- U / V default 0.5 (clamped to 0–1)
- Disconnecting the input resets it to black / 0
Readback happens once every 3 frames, and because reading back from the GPU is asynchronous, the value lags by several frames. If you sweep U/V quickly, the color you get is from a slightly earlier position.
