How to Optimize Your Blender Scenes with Limited Dissolve

In this video, we build on our first interior render in Blender by optimizing the mesh for better performance and cleaner geometry. Starting with a complete home layout from Sweet Home 3D, we walk through selecting the camera, enabling viewport statistics, and using wireframe mode to analyze topology.

Learn how to:

Set the active camera for accurate scene navigation

View and analyze geometry stats in the viewport

Use Limited Dissolve to reduce face count from ~390,000 to ~80,000

Adjust the dissolve angle to balance detail vs. performance

Preserve material boundaries while simplifying the mesh

Restore detail in key objects like the fridge by tweaking dissolve settings

By the end, you'll understand how to clean up unnecessary geometry—especially on flat surfaces like floors—while maintaining visual quality. Perfect for anyone looking to streamline their Blender scenes without sacrificing aesthetics.
