Rendering bugs included floating and upside-down palm trees.

Haha, great catch🤣 Opus 4.8 apparently decided palm trees are exempt from physics.

At first glance the scene looks great, but the zoom-ins tell a different story: floating trees, upside-down trunks, and palms growing straight out of buildings 🌴

Here’s the zoom-in video😂

The desert vibes are real, but so are the anti-gravity palm trees 🌴
