Known Issues with 1.2.20

The new terrain rendering feature in aven is still somewhat experimental, and has a few known limitations:

• #55 You can see the terrain through itself, which isn't meant to happen
• #56 The altitude of the terrain and altitudes from GPS fixes don't match (typically off by a few 10s of metres)
• On Windows, loading terrain from a zip file doesn't seem to work, but as of 1.2.20 you can extract the zip and load the files directly from disk instead
