Is it best practice to keep sampler types inside or outside of GLSL structs? I have read online that some drivers might have issues with this but all posts were fairly old. Is this something worth taking into account now a days?
Thank you!
#Sampler2D in GLSL struct?

I have always kept them outside. Texture and buffer bindings are descriptor / bind group like stuff, so they are different from other stuff
I would reorder members to match the layout rules - groups of 4 components, so vec3 should always start at multiple of 4 components, and be followed by one component, dummy padding if nothing else exists.

by dummy padding do you mean like a fundamental type that's never called?

vec3 cameraPosition; float dummy;

perfect, thank you for the advice! Its great to know

Note that using sampler array consumes multiple texture units. You could use array texture instead - that way it consumes only one texture unit.

Great to know as well, I did not know about array textures.

you can only put them in structs if your structs are part of a regular uniform. you cannot use structs containing opaque types in buffer backed interface blocks unless you are using bindless, which I'm assuming you probably aren't
