I was able to create 2D Normal Map reflections using GDevelop Light object 💖
The current system supports:
Multi lights reflections in the same time.
Green channel flip (Flip Y).
Takes gdevelop ambient light color into account.
Takes the light object radius into account.
Respects light obstacle behavior.
Sprite animations.
Light object color.
Ambient boost.
Intensity.
Pixel perfect & smooth.
And much more ! :3
Most likely I will turn it into an extension to make it super easy for everyone to use 😊
