    Hi

    Recently I have been getting a lot of errors the first time I select the terrain tools in the editor.
    Once all tools have been selected there are no more errors until i deselect the terrain and open it gain.

    See the attached image.

    It happened after updating the editor from 2021.2.11f1 to 2021.2.16f1.

    Anyone have any idea on how to fix this? It would be greatly appreciated as configuring my project again from scratch is a pain. Offcourse I can rollback to 11f1 but 16f1 fixes some other errors.

    It seems to be a project thing. Removing Terrain tools and using the builtin functions have no errors.

    Creating a new empty project with a new terrain does not have this error.

    It also creates some filterstack files in the application persistent folder. Id be happy to upload them if you think it can help.

    Same issues, and was able to stop the errors, but still not able to sculpt. Most say read only, and if it doesn't it still doesn't draw.

    Fix seems to work for me.. seems to be an issue with the Masking system. I susspect the issue maybe related to the UI as it mucks up whenever I select an edit option without a filter and it outputs to error.

    Just to confirm fix for any having issues. You need to add a mask type to every edit option.. should be 19. Shink the Terrain inspectors foldout and re-expanding it if the ui screws up, then add ony of the filter types and disable it. Once every edit option is done you shouldnt get any errors.

    I've just had the same issue with 2020.3.33f1 LTS. Not entirely sure, but importing the Standard Assets pack seems to have caused it as I was able to use before that TerrainTools 3.0.2 for about an hour without errors. Afterwards this would occur any time I had TerrainTools installed regardless of its version. After some investigation:

    2020.3.33f1 LTS - this occurs with TerrainTools 3.0.2 regardless whether I have the Standard Assets pack, none of the fixes/workarounds in the thread posted above seem to be working,

    2021.2.17f1 - occurs as soon as I install TerrainTools 3.0.2 regardless whether I have the Standard Assets pack, the brush mask workaround seems to have fixed the issue,

    2021.3.4f1 - appears fixed with TerrainTools 4.0.3 regardless whether I have the Standard Assets pack.

    It should be noted that previously affected projects got fixed after restarting each in 2021.3.4f1 and importing TerrainTools 4.0.3 (3.0.2 disappeared from the package manager after and was not available anymore).

    I'm having the same issues in unity 2021.3.2f1 with terrain tools 4.0.3
    sometimes the above workaround helps but mostly I can not use any of the tools
