3D tex sometimes switches to a different 3D tex (build only)

[robosoup2]

In a build of our game, you can reproduce (SOMETIMES?) by doing the following:

• instantiate a new 3dtex brush (just one)
• instantiate another; the previous 3dTex brush starts using the 3dTex from the new prefab.
• if 3Dtex "A" has more than one copy in the renderer (for example, if I had placed 2 t rex heads) then the issue won't occur

let me know if there's anything I can do to help debug this 🙏

I finally encountered the issue in editor, which must be very rare compared to build
I was able to peek and see that the correct SDF was still assigned in the inspector, even while it was using the incorrect one in reality
