“Blender Just Changed Forever”: an Overview of new 4.5 Features

Smeaf takes a closer look at Blender 4.5 and highlights how this release reshapes everyday workflows.
He focuses on the following main changes:
- Manifold Boolean Solver: The new solver delivers buttery-smooth, real-time boolean operations, eliminating the glitches and performance bottlenecks of the past. This is a game-changer for modeling, sculpting, and animation workflows, especially for complex or animated booleans.
- Fluid Simulation Stability: Mantaflow receives significant stability and UI improvements, with baking speeds up to 1.5x faster, making water and liquid simulations more predictable and efficient.
- Geometry Nodes Expansion: New nodes like Normalize Mesh and Camera Info open up creative possibilities, allowing artists to join geometry without topology destruction and create camera-based effects.
- Animation Workflow Upgrades: Snap-to-keyframes, duplicate shape keys, and bone overrides streamline character animation, saving time and reducing frustration.
- Vulkan Backend: After six years of development, Blender replaces its decades-old OpenGL system with Vulkan, unlocking multi-core CPU utilization. The result? Faster load times, smoother viewport animation, and improved performance across the board—even with high-poly models.
