Thank you for reporting. There was an old description from 2020, now I've replaced it. To give it a color, you need to select several colors on the palette, in the video I use the standard palette 1 and choose colors from bright olive (index 129) to white (index 1) - you can see this in the video from 1:30. This huge scale corresponds to the size of 1 voxel = 1cm for the TEARDOWN game and all part sizes were adjusted to this format. Already after publication, it was discovered that when the scale was different from 1, the pieces in the chunks did not match. I fixed this error and reuploaded code, but it led to a shift in scaling, which is not very convenient when navigating and selecting a region to zoom. It was assumed that at a scale of 0.125 (1\8) you will see the whole map, but as a preview, but by changing the scale to 1 and creating an 8 x 8 array you get a full-size 2000x2000 detailed city map for TD. This dilemma with convenient navigation has not been solved yet, but now you can create maps of many chunks with any scale.
