3DS Max not sharing UVs between instanced meshes?

NeonGold

So for some reason when creating an instanced copy of a mesh it seems to be creating its own set of UVs for each of the instances instead of using those of the parent and I can't quite figure out why. I have a small bush I'm trying to make (just made of planes) and the object I'm copying are two intersected planes with UVs. I Shift-Instance those, collapse all, check the UVs, and suddenly the UVs for every plane in the scene are there. What am I missing? <br><br>Any insight on this frustrating hiccup is greatly appreciated .&nbsp;

If the planes have been unwrapped and the UVs baked(collapsed stack) then this should never happen. Are you sure you unwrapped them as opposed to just using UVW mapping?

Collapse all is breaking the instance relationship and makes the collapsed object unique.  If you want the stack to be flat (collapsed), simply do the collapsing before instancing..

Yes, but once an instance that had its uvs unwrapped is collapsed then the uvs are baked into the mesh.

Use "collapse to" and not "collapse all", to preserve instances while collapsing the stack.

Hi Neon...I tried a couple of different examples of instanced copying w/ a model (including only portions of it) I'm working on and have not run into that problem. I'm using Max 2015. You don't have part of it isolated/hidden do you?

This. And If the text in the modifier stack is not bold, it's not an instance anymore.
