Never seen a pattern like that in Terrain Editor.

1. Did you check the "fractal" checkbox at the start? That would be incorrect, as you are using a heightmap to create a terrain mesh, not a procedural ('fractal") terrain.

2. Best to use multiples of 16 (256 x 256, 512 x 512, 1024 x 1024).

3. Usually you want a blend of 100%, so only the heightmap controls the terrain (unless you are mixing a heightmap + an existing terrain).

4. Not sure about Vue 4. Above is for Vue 5 Infinite.
