Squares in the sky - TerminatorNL/LagGoggles GitHub Wiki

The colour is calculated by the contents of the chunk, and not the chunk itself. All contents in the chunk are summed up, and a gradient is created. To make this chunk turn completely red, the sum must be 10 times higher than the GRADIENT_MAXED_OUT_AT_MICROSECONDS option in your client
