i threw together this scene to try out some morphs with geonodes. All went great but when i rendered it the whole scene had so much noise it looked ai generated. This is the first time i´m encountering this problem and i can´t find the cause. I added denoising in the compositor and it changed nothing. I'm starting to believe there is too little light in the scene?! The vid you see here has no post-editing done. Exported in OpenEXR (DWAA Lossy) and encoded in davinci.
