Ressurecting an old thread.
We have been using this env variable to make usdpreview surface whats picked in the viewport but what we really wanted was just to change prio order of what the viewport uses when having a collect node.

Usdpreviewsurface
materialx
other shader

The reason for this is that we want to show some mtlx shader in the viewport also, for example imageplane where we have more control. But now that one wont work.

TLDR
change it to priority instead of turning off mtlx shader in viewport

You are probably right and I cant say im an expert in encapsulation. I hoped this would still be considered a composition arc where its a stronger refenrece/layer without messing with the underlying reference and break encapsulation. So In my understanding was that encapsulation was presered and proper overrides strength order was applied.

In this example i assumed references and sublayer to work the same but seems like it doesnt.

The goal is to have an assembly of grass and then do a sim ontop of that and then retime instance them. When layering them as an asset it breaks. Layering them as sublayer works fine. In this case we would prefer to have it in the reference because we are reusing the asset in different shots.

Wondering if somebody is usd savvy enough to know if this is intended or not
