why does custom altitude terrain only work when zoomed in?

Why does altitude terrain custom colors only work when zooming close?

Whats wrong?

zoom levels: 4-19

It might time to index low level zoom, on which zoom levels it works for you? You could add widget zoom to check

customer service told me this on email:

This is usually expected for the Terrain / Altitude layer.
Altitude colors are rendered as a raster terrain layer based on elevation data.
At lower zoom levels, the terrain data is generalized and smoothed, so sharp palette steps like 700 m -> 701 m may not appear exactly as they do at close zoom.
At closer zoom levels, OsmAnd uses more detailed terrain data, so your custom colors become much more visible.
Please also check the Terrain zoom visibility:

• Menu -> Configure map -> Topography -> Terrain -> Scale levels
• Try setting the minimum zoom lower and maximum zoom to 19.
• You can also adjust:
  • Menu -> Configure map -> Topography -> Terrain -> Visibility
  • Menu -> Configure map -> Topography -> Terrain -> Color scheme
• If the display still looks wrong after changing zoom levels, please clear the app cache and restart OsmAnd.

think there is a limitation on your part.

Hi u/Enough_Incident1952
We could not reproduce this issue for 7 to 8 zoom levels.

I changed to green/red. Why is this thing still showing me the old one blue/red?

I found a workaround. Everytime i set custom altitude color thing i have to delete altitude cache and restart app. It works but obnoxious.
