ok so this as been bugging me for a while.
I am looking to fully optimize my exported characters so I want the different levels of the LOD mesh with the original. so use  "instaLOD" right?

only I don't want the original to have so many materials ether, I want the original to have  "Merge UV" so each character only has about 5  materials at most between the main mesh and the LOD

so why not expert them separately and combine them in unity ?
well that is were im at. as you can probably guess the only problem is the original and LOD are using  have separate skeletons and therefor  can't be controlled bay the same animator the same way expecting LOD with original would work.
how can I fix this ?  

I actually can do something similar with this code

  1. using System.Collections;
  2. using System.Collections.Generic;
  3. using UnityEngine;
  5. public class Equipmentizer : MonoBehaviour
  6. {
  7.     public SkinnedMeshRenderer TargetMeshRenderer;
  8.  
  9.     void Awake()
  10.     {
  11.         Dictionary<string, Transform> boneMap = new Dictionary<string, Transform>();
  12.         foreach (Transform bone in TargetMeshRenderer.bones)
  13.             boneMap[bone.gameObject.name] = bone;
  14.  
  15.  
  16.         SkinnedMeshRenderer myRenderer = gameObject.GetComponent<SkinnedMeshRenderer>();
  17.  
  18.         Transform[] newBones = new Transform[myRenderer.bones.Length];
  19.         for (int i = 0; i < myRenderer.bones.Length; ++i)
  20.         {
  21.             GameObject bone = myRenderer.bones[i].gameObject;
  22.             if (!boneMap.TryGetValue(bone.name, out newBones[i]))
  23.             {
  24.                 Debug.Log("Unable to map bone \"" + bone.name + "\" to target skeleton.");
  25.                 break;
  26.             }
  27.         }
  28.         myRenderer.bones = newBones;
  29.  
  30.     }
  31. }

that lets me map extra clothing onto a character however when i try with the LOD the mesh stops rendering altogether.
any thoughts ? 
(I will look back this evening got work now)

Do you add the skinned mesh renderer (myRenderer) of the mesh object to the LOD group > LOD Level renderer list?

That may be why it's not rendering as it only renders what's specified in each LOD level.
By Jbowdoin - 3 Years Ago
Yeah I did and its not rendering despite that .

not rendering is tied to the code, the moment i put that on the LOD model it stopes even if I remove the LOD group all together.
I know its the code that I use for trying to merge the skeletons that dose that and yet it works just fine for clothing 
which is why I'm considering other options

has this not come up before?

surly im not the only one who wants both optimized materials and LODs lol
By Jbowdoin - 3 Years Ago
no luck it seems -_-

why is it so hard to find info on this ?
I know its doable, how else do people set up LOD's from other software to use one animater any way?
By Victor.Soupday - 3 Years Ago
The principle is sound, the problem is it requires all the original bone transforms of all the LOD levels to be carefully preserved, at least until after they have been combined, but also the bone names in the various LOD models exported from CC4 are not necessarily the same, and some LOD exports add extra bones which all need to be untangled for correct retargeting. If any bone fails to retarget it won't draw the mesh.

I've been working on a tool to combine the LOD models from the new LOD generation system in CC4 (Optimize and Decimate) which basically uses the same principle of retargeting the skinned mesh renderers to a set of common bone transforms and re-structures the transform hierarchy so that animations (include blend shape animation tracks) play correctly on all levels, but it does it in the editor and generates a new LODGroup prefab:



With modification it can also combine the multi LOD level exports from InstaLod with any custom character LOD and do exactly what you need.
