Ursina Python Engine: Lighting, Shadows And Bloom Effects

Question

I Am New To Ursana Engine And I Don't Know It Properly. But I Can Make Games In It. But The Problem Is That My Game Doesn't Have Any <Shadows, Glow, Lighting or Bloom>. So My Game Looks Dead.

Is There Any Way To Make My Game Look Good Using <Shadows, Glow, Lighting and Bloom> In Ursana Engine?

You have to import shaders from ursina and then apply directional light.

from ursina import *
from ursina.shaders import lit_with_shadows_shader 

app = Ursina()
EditorCamera()
Entity(model='plane', scale=10, color=color.gray, 
shader=lit_with_shadows_shader)
Entity(model='cube', y=1, shader=lit_with_shadows_shader)
pivot = Entity()
DirectionalLight(parent=pivot, y=2, z=3, shadows=True, rotation=(45, -45, 45))

app.run()

Also, how do you control the brightness of `AmbientLight` – SamTheProgrammer Mar 17 '22 at 17:00
As ursina is made from Panda3D then you can go to this [Panda3D Lightning Docs](https://docs.panda3d.org/1.10/python/programming/render-attributes/lighting) and see the [Coloured Lights Section](https://docs.panda3d.org/1.10/python/programming/render-attributes/lighting#colored-lights) – Tanay Mar 17 '22 at 19:08

did you find it useful? – Tanay Mar 19 '22 at 10:16
Somewhat, but I believe that there is a direct Ursina implementation I used a while ago, but I can't remember what it is. It should just be a parameter to AmbientLight() – SamTheProgrammer Mar 19 '22 at 10:49
Perhaps alpha=[whatever-value]? I will try it later. – SamTheProgrammer Mar 19 '22 at 10:50

I am also exited to know how to do so if you found something please tell me. – Tanay Mar 19 '22 at 15:13

@Password-Classified i found the solution `AmbientLight(color = color.rgba(100, 100, 100, 0.1))` – Tanay Apr 01 '22 at 13:14

You can change the rgb values and alpha if you want – Tanay Apr 01 '22 at 13:15

You have to add lights and also apply lit_with_shadows_shader to entities that will receive shadow.
