I have two MeshInstances. First with CubeMesh and second with ArrayMesh. I assigned water material on cube and for ArrayMesh(triangle) i have this code:
var vertices = PoolVector3Array()
var arr_mesh = ArrayMesh.new()
var arrays = 
arrays[ArrayMesh.ARRAY_VERTEX] = vertices
var id = arr_mesh.get_surface_count() - 1
self.mesh = arr_mesh
How can I make the triangle looks like the cube?
