Hi Im using JME2, I want to create a MeshCollsionShape from a terrainBlock with the same heightmap as My terrainpage.
Problem is the terrainPage stays on 0,0,0… I tried translating the terrainBlock but it seems that the created meshCollisionShape is still on 0,0,0… So, how do i translate my terrainBlock same as the translation of my terrainPage.
Thank You
Screenie:
The colored one is the terrainPage, the grey is the terrainBlock
Here my code,
SpaceTerrain2.class creates the terrainBlock, terrainPage
