    Hi,

    Any chance to increase these limits to 4096 (same as actual Heightmap resolution limit) in some future update?

    Thanks

    I have a change in flight that raises the limit for both to 4k. Hoping it will make it into 2019.3.

    Just wanted to ask how things are going? Will it make it into 2019.3?

    Thanks.

    Since it's (still) not in the Unity documentation ... what does the text "Require resampling on change" actually mean in your screenshot?

    There are no API methods with a name anything like that, apart from SampleHeight (which definitely is unrelated). And, of course, the docs for Unity Terrain are still "haven't been written yet, since 2011...", so ... Shrug.

    What it seems to mean is:

    "The first field will do nothing. But the 2nd and 3rd fields below it will create automatic 'RESIZE' buttons if you start editing them. If you're using the API, no resampling is required, this message is a distraction".

    I'm guessing the Helpbox is positioned incorrectly in the inspector (it should be one row lower), and that resampling is ONLY a requirement when editing via the inspector.

    NB: as documented in another thread, the inspector is broken here anyway: it forces POT textures when there's no need for them. Short answer: don't use the Unity Terrain inspector when editing terrains, instead write your own one.

    Is there plans to add support for compressed (DXT1/DTX5 etc) base map textures? Rendering a large amount of terrain with an uncompressed texture isn't really ideal for performance.

    Hmm, yeah that is probably badly worded. It's supposed to just be a warning that changing the height or control resolution will automatically re-sample your data, which is a destructive operation.

    The heightmap requires power of two + 1 resolutions, but the control and base texture resolutions are more flexible, it's true. Should probably add an "other" choice in those drop downs.

    We do not have plans to add compressed basemap support to Terrain in the immediate future; but that's something we will look into for the new renderers we are building.
