Hi! I need Your help with script becouse without it I can not put the other script on the player. Maybe You know what need to do? It writes “The nested type MeshInstance' does not exist in the type MeshCombineUtility’”.
using UnityEngine;
using System.Collections;
/*
Attach this script as a parent to some game objects. The script will then combine the meshes at startup.
This is useful as a performance optimization since it is faster to render one big mesh than many small meshes. See the docs on graphics performance optimization for more info.
Different materials will cause multiple meshes to be created, thus it is useful to share as many textures/material as you can.
*/
[AddComponentMenu("Mesh/Combine Children")]
public class MeshCombineUtility : MonoBehaviour {
/// Usually rendering with triangle strips is faster.
/// However when combining objects with very low triangle counts, it can be faster to use triangles.
/// Best is to try out which value is faster in practice.
public bool generateTriangleStrips = true;
/// This option has a far longer preprocessing time at startup but leads to better runtime performance.
