lookupSkipThreshold property
The magnitude under which texture lookups will be skipped.
You probably don't need to change this.
Default: 0.01
Details
The hex tiling shader mixes between up to three texture samples per fragment. As an optimization, if the magnitude of one particular mix is below this threshold, the texture lookup will be skipped to reduce GPU memory bandwidth usage.
If the final coefficient of a texture sample is less than lookupSkipThreshold, the texture lookup will
be skipped.
Implementation
double lookupSkipThreshold = 0.01;
