Blender 5.2’s New Grease Pencil Fill is a Game Changer

Blender 5.2 LTS introduces a game-changing update for 2D artists: the Delaunay Fill Algorithm. In this in-depth tutorial, I explore why this shift from pixel-based flood fill to a geometric solver is a “huge deal” for Grease Pencil users.

The new engine provides faster, more accurate fills that are zoom-independent, finally solving the frustration of “unable to fill” errors on complex geometry. The video breaks down the technical differences between the old Pixel method and the new Delaunay Solver, demonstrating how the update handles gap detection and “Internal Gaps” with far greater precision.

Viewers will also learn practical workflows for Inverse Filling and how to navigate the new settings in the Grease Pencil 3.0 transition. Whether you are a professional animator or a hobbyist, this guide ensures you are ready to master the most significant improvement to coloring in Blender 5.2.
