Hmm, seems like there is an issue here. Comparing 5.3.12 map with 5.3.16 map as attached. Not sure if it might be a side effect of something else, as I think the colour range is OK sometimes (I think I noticed some irregularities with 5.3.15 but assumed I was imagining things at the time) - maybe the preview below triggers it? - I might investigate further if I get time.

Lately I noticed Therion color gradient starts from 0 m altitude to maximum cave altitude. Because caves don't reach 0 m almost all color range is unused and most scraps are colored with similar colors. If I remember correctly some time ago Therion used all color range because color gradient extended from minimum cave altitude (not 0 m) to maximum. Am I missing something? Is there a way to use all available colors? Thanks, Marco
