reflections with baked scene and 1 spotlight...

Hi

im making a cave scene with baked lighting and 1 realtime spotlight (built target is oculus quest). Im no expert at lighting and so dont really know what you can and cant expect to get using the various types of light whilst baking.

I have a material that looks great when using a directional light (see attached) however, when i use it in my scene with baked lights I get no reflections (due to lack of directional light i suppose).

My question is, is there a way i can achieve a similar effect for question whilst baking my scene?

Ive tried using a reflection probe but without any luck.

many thanks for your help!
Nick
