I've been messing a bit with an editor for somebody and am trying to deform the terrain.

I can get the polygon they clicked on which is fine, but in the VertexController the mesh size is only 1024 (the terrain region is currently 32x32 with 2 triangles per 'tile'). So I was wondering how exactly the getDestinationMesh()

• applies to the actual mesh.

The array size seems to be 1024 so 1 index per tile, but each tile is made of 2 polygons so how does this work?

When I try to deform the terrain the polygon they clicked on I thought might have been just *2 the index since there are 2 triangles per, but it doesn't seem to be the case and the actual location I change is off from where I am clicking.

Thanks in advance for the help.

Hey I was using one of the examples here (that I typed out line by line and omitted some of the objects and stuff) and then I ended up changing the plane size to be almost double in size. Whenever I start moving around a bit and rotating the camera, it seems to crash and spits out an ACCESS_VIOLATION.

Here is the minimal output, if you need the full log just ask and I can post it.
