So for this biome sampling, the 5D point of temperature, humidity, continentalness, erosion, and weirdness should be taken from the block's (x,y,z) position but then another sample should be taken depending on the W position and those two should be blended sogether in some way. This will lead to slices roughly keeping similar biomes but some slices will have more temperature or maybe more weirdness, allowing from each world slice to have it's own unique feel to it.
