Question
As the title,I have read a lot of docs and tutorials but i didn’t find any about filters
i have not find any available way to solve this problem
maybe a bit more description what you mean with filter ? Camera , there is option for Composition where I believe you can make lots of thing to happen.
From screenshot I assume you on about light transmission and color change through alpha transparent surface ?
Yup, what I want is a filter that can change the color of the light that passes through
Using the word ‘filter’ can indeed cause a lot of ambiguity sry
Changing the color of light in the world does seem to be quite troublesome
Thank you very much for your reply
so what is your current setup for it ? - settings in material section
Did you use shader material, standard3dmaterial ?
cube, plane for “filter_effect” ?
I have absolutely no idea on how to make this effect bruhhhh
maybe material or shader?
You don’t know what you did in scene ?
Provide much info as you can, people then might wants to help you if they know answer then .

What do you need this for? What’s the specific use case?
Are you thinking of those color filters you can put in front of lights to change the color? Like a white LED and a red filter to get red light?
If so, you can’t do this with traditional lighting models. Normally, lights don’t understand the world: an infinite wall can separate a light and a character, and the character would be “lit,” (ignoring shadowing techniques for a second.) I’m not saying it’s impossible, just that the solution might not be intuitive or realistic. (Maybe you can just project a texture?)
However, Godot has some global illumination features where light does behave more realistically. I don’t know how “light filters” will work with global illumination but that’s where you’ll find light behaving more like real world light.
