With Brushify you can eliminate Vertical stretching on landscape slopes using the built-in Tri-planar Mapping feature.

In this example Tri-planar mapping is used on a large vertical cliff wall.
How to Enable Tri-planar Mapping
1 - Open MI_Landscape
2 - Find 'Reduce Texture Stretching on Slopes (Triplanar)' tick box and enable both tickboxes:
3 - Wait for the shaders to compile.
4 - Triplanar is now activated
Voxels
Because Tri-planar mapping allows for vertical walls, it also works well with the Voxel Plugin (read more about that here) Holes and Vertical walls are textured without stretching.
