Ursina - how to add fog correctly

Question

I'm (once again!) asking about a problem with Ursina...

I know that Ursina has a scene.fog, and I'm kind of assuming it's for 3D games. I want to add fog to my game, but setting scene.fog_density and scene.fog_color does nothing.

Am I doing something wrong? How do I add fog to my game?

I'm using the (mostly) default FirstPersonController

My code:

app = Ursina(development_mode=False, show_ursina_splash_screen=True,fullscreen=True,title="Maze FPS")

random.seed(0)
### SHADERS ###
Entity.default_shader = lit_with_shadows_shader

scene.fog_density = .1
scene.fog_color = color.red

I've tried various fog densities (.1, 1, and 3) and colors (color.black, color.red, color.green). afaik it didn't have any effect

Please show what you did. Otherwise it's very hard to say if you did something wrong. — pokepetter, Jun 08 '22 at 17:28
@pokepetter, ah, you're right. Don't know why that didn't occur to me. Sorry! I've added the relevent code. — Psychon Night, Jun 08 '22 at 18:45

The lit_with_shadows_shader doesn't support fog at the moment. The default shader does however. The way you set fog color and fog density is correct.

So I'd need to switch everything to use the default shader if I wanted to use fog? – Psychon Night Jun 10 '22 at 16:20
@Psychon Night There is no shader by default. – Tanay Jun 13 '22 at 10:12
@pokepetter can you help me to make realistic water in ursina? – Tanay Jun 14 '22 at 03:34
