There is an effect I never found how to do it, and until now I always used some tricks with 2d sprites. But there are cases where it won’t be possible to fool the eye. In a nutshell, how can I make a material glow? The glow parameter never did anything in my attempts.
How can I do something like this?
It´s done by a shader.
It´s called: Bloom Shader.
…a post process shader (pixel shader).
There are a lot of tutorials for HLSL or GLSL Bloom Shaders.
Take a look around in the web.
Started some days before with Godot. Not touched it´s shader-system so
i can not tell you much how to do it in Godot but if you understand
GLSL or HLSL it should not be a problem to implement it in Godot.
Godot offers Glow and Bloom settings. In order to use bloom, you need to enable glow first, then set bloom to a value above 0. You can do this in a WorldEnvironment node.
