New Terrain System - How Do I Work Around This?

public SurfaceData GetSurfaceData(Collider collider, Vector3 position, int triangleIndex)

        {

            Texture texture = null;



            // If the ground is a terrain.

            if(collider.GetType() == typeof(TerrainCollider)) 

            {

                Terrain terrain = collider.GetComponent<Terrain>();

                TerrainData terrainData = terrain.terrainData;

                float[] textureMix = GetTerrainTextureMix(position, terrainData, terrain.GetPosition());

                int textureIndex = GetTerrainTextureIndex(position, textureMix);

                texture = terrainData.splatPrototypes[textureIndex].texture;

            }

            // If the ground is a normal mesh.

            else

                texture = GetMeshTexture(collider, triangleIndex);

       

            if(texture)

            {

                for(int i = 0;i < m_Surfaces.Length;i ++)

                    if(m_Surfaces[i].HasTexture(texture))

                        return m_Surfaces[i];



                return m_DefaultSurface;

            }

            else

                return m_DefaultSurface;

        }

Not used to the new terrain system yet, and I am trying to update an older project. How do I fix the Splat texture obsolete error? Not a gamebreaker...but driving me bonkers.
