When Shader option is set to off the Trident Livery disappears and the dent looks normal.
Shader set to Automatic Trident Livery is shown.

Uhum, I would think that is normal? Not having Shaders enabled doesn't show a texture that is drawn by a Shader.

But what do I know, I'm just a frog. Ribbit.

Inc asked me to post it so they could look at it.

I didn't understand what you were trying to say via Discord. I thought there was a bug.

Yes, disabling Shaders will disable graphical functionality enabled by shaders. That is the expected behavior.
