"Selected File must bewithin the project directory"

[peq42]

Whenever I try openning a file for the sky texture, I get that message. IMO, there's no point in having a file selector if that is a requirement.

Either A) files should be selectable from the resource tab, kinda like unity does or B) once picked through a file selector, they should be copied to the project's folder

The issue is that you are trying to select a file that isn't part of the project.

While the system could automatically transfer it when you attempt this, it really comes down to usability design choices.

To use it, simply go to the "Resources" window, right-click, and select "Import File". Or just drag and drop the file into that window.

Once you've done that, the file becomes part of the project and can be used anywhere.
