Question
How can I code shader of pixel glow.
More specifically: I need a shader that creates a pixel glow around an object. As far as I know it’s impossible to do this with the engine’s built-in tools.
Try using the WorldEnvironment node with glow enabled.
Here’s a tutorial I recently used.
It’s not specifically for pixel art, but I don’t see why it wouldn’t work for it.
