Post
Applies post-processing effects and creates feedback loops by blending the current frame with the previous one. Right-click to adjust blend mode, opacity, scale, and gain.
Post does three things on every frame:
Takes a snapshot of whatever was drawn.
On the next frame, blends that snapshot with the new frame.
Outputs the result so the loop continues.
The Post node doesn’t require any input to work. Simply placing it in the editor creates an independent post-chain, marked with a purple connection line. This gives you a dedicated place to build post-processing and feedback effects without rewiring anything in your main graph — Post always reads the final composed frame.
If you want to understand how feedback works, why Post behaves the way it does, and how to use it in your creative workflow, check out our guide on Feedback Loops.
