# SetMeshMemblockVertexNormal

## Description

Provides a quick way to modify the normal of a vertex inside a mesh memblock. It uses the attribute data from the beginning of the memblock to work out the vertex offset and change the normal values. Vertices start at index 0.

## Definition

SetMeshMemblockVertexNormal( memID, vertexIndex, x, y, z )

void agk::SetMeshMemblockVertexNormal( UINT memID, UINT vertexIndex, float x, float y, float z )

## Parameters

- memID - The ID of the memblock to modify
- vertexIndex - The index of the vertex to modify
- x - The X component of the new normal for this vertex
- y - The Y component of the new normal for this vertex
- z - The Z component of the new normal for this vertex
