HI,
Actualy landscape layers are shown as a list in the paint tool which is painful to use while working with many of them as you have to scroll up and down.
The “layer info” name takes a lot of space which is useless.
The content browser has the option of showing content as list, column or grid (tiles) so I guess it’s shoudn’t be not hard to implement (for someone who know how to edit the engine UI)
Here’s what I mean :
And a way to use the picture of the diffuse texture as layer icon, instead of a sphere with the compiled material. Because depending of a how you made your landscape material, all layer icons could look the same.
