How to use a lightmap texture in the shader graph

Hello everyone, I have a lightmap texture and I want to apply it to my shader, how do I do that?

 

What do you mean ?

Where does this lightmap come from ? What is on it ? An object, a entire scene ?

 

is the light map of the entire scene

 

Where did you do the scene ? In a 3D software or in Unity ?

If you did it in a 3D software, you should probably import the scene in Unity and bake the lightmap with it. Change parameters to get a result as close as possible as you have already done.

Or else, if it is from Unity, you do not need shader to see. It is already visible normaly when you are in the editor or in game.

Can you provide some images ?

 

I made the scene in unity

 

I wanted to put my own light map

 

From where ? Where have you baked this lightmap ? Because Unity can make one for you directly usable.

 

I made a procedural level system and also a light map generation system, but I don't know how to apply my light map that is being generated

 

it creates the light map per pixel

 

The global variable for the lightmap should be unity_Lightmap, and you'll need to take some extra steps to access that:

Keep in mind that you'll also have to make sure you're using the right UV set to access it, which should be UV1 instead of UV0

 

Hey bro, did you find a way to implement my own lightmap? my lightmap baked from blender @GamesStudioDreams @Murgilod
