Material Preview Window Not Staying Docked in Slate Editor After Restart

[hvarsani429]

Every time I restart 3ds Max, the Material Preview window in the Slate Material Editor disappears and does not retain its previous docked position. I have to manually reopen and reposition it every session. Is there a way to keep it docked permanently or auto-load a saved UI layout with it docked?
I'm using 3ds Max 2025, and this issue persists even after saving custom UI schemes.

Any guidance or workaround would be appreciated.

Hi @hvarsani429,
Thanks for participating in the Community!

Has this always happened, or has it occurred since a new update, or any computer change?

Thanks!
