Pixel Art Shaders v1.4.0 – Update Log (2025-12-04)

New shader effect - Iterative Fire

• Iterative Fire: a feedback-driven animated effect built on the Utility class FeedbackTexture. It evolves frame-by-frame, producing lively flame motion with palette control.
• Fancy Demo and Examples added to the live-demo

• Setup: this shader requires rendering into a texture each frame and feeding that texture back as previous_frame in the next draw. If you prefer not to implement the feedback loop yourself, you can purchase the examples and utility classes for a plug-and-play setup, watch my Youtube-Short with the explanation or use the free GIF/spritesheet export to capture the effect output.

Premium Content Changes

• Added enhanced example scenes demonstrating advanced shader usage for iterative fire
• New Example Scenes for iterative fire shader:
  • example-scenes\mage-maging.tscn
  • example-scenes\falling-godot.tscn
  • example-scenes\godot-burning.tscn
• New Helper Classes:
  • FeedbackTexture - Creates SubViewport and texture handling for the read/write dynamic to have shaders effect apply iteratively addons/pixel-art-shaders/helpers/feedback_texture.gd

UI and workflow improvements

• Image borders: under "Image Settings" you can add borders around the source image. This lets effects extend beyond the original texture bounds (useful for glow, fire spreading, outlines, etc.).
• Added UI for secondary color palettes, that is (optionally) used by the new effect

Fixes

• Single sprite with background now properly positioned and scaled

Technical Details

• Version bump from 1.3.0 to 1.4.0
• New Iterative Fire shader does not work to it's full extend without additional scripting (examples available in the premium package)

Migration Notes

• No breaking changes from version 1.3.0
• All existing shaders remain fully compatible
• New shader works only properly with a SubViewport Texture feedback loop.
• Existing projects will continue to work without modifications
