AO Connector is an automated Blender addon that simplifies the process of adding Ambient Occlusion (AO) to materials. It intelligently detects your material setup and automatically creates the proper node connections to enhance depth and realism in your 3D models by adding subtle shadows in crevices and contact points.

The AO Connector panel is located in the Properties panel under the Material tab. Once installed, you'll see the "AO Connector" section with collapsible categories including Actions, Preview, AO Properties, Utilities, and Special Toggles.

AO Connector works with materials that use a Principled BSDF shader with node-based setups. It can handle both simple procedural materials and complex PBR (Physically Based Rendering) materials with multiple texture maps. The addon intelligently detects Base Color, ORM (Occlusion/Roughness/Metallic), and separate AO textures.

Yes! One of AO Connector's key features is batch processing. You can select multiple objects and apply AO to all their materials simultaneously with a single click. This is a huge time-saver when working with complex scenes containing many objects.

Yes! AO Connector provides real-time adjustable parameters including: Distance (0.01-10.0): Controls how far the AO effect reaches Samples (1-128): Affects quality and render time Intensity (0.0-1.0): Controls the contrast/strength of the effect Shadow Color: Allows you to tint the AO shadows All changes update in real-time on selected objects.

The AO Preview Toggle allows you to quickly turn the ambient occlusion effect on and off in the viewport without removing the nodes. This is useful for comparing your scene with and without AO to see the visual impact, or for faster viewport performance when needed.

The Lock AO feature prevents the addon from modifying a specific material's AO setup. This is useful when you've manually customized the AO nodes for a particular material and want to protect those changes from being overwritten. You can lock the active material individually or unlock all materials on selected objects at once.

AO Connector is smart enough to detect ORM (Occlusion/Roughness/Metallic) packed textures commonly used in PBR workflows. It automatically extracts the Red channel (Occlusion) using a Separate Color node and combines it with the procedural AO node, giving you the best of both texture-based and ray-traced ambient occlusion.

The Ambient Occlusion node does add computational cost, especially in Cycles renderer. However, AO Connector provides controls to balance quality and performance: Lower Samples values render faster but may appear noisy The Distance parameter can be reduced to limit calculation range Use Only Local to exclude inter-object calculations The Preview Toggle lets you disable AO during iterative work

Absolutely! The addon can detect standalone AO texture maps and intelligently combine them with the procedural AO node using multiply blending. This gives you enhanced ambient occlusion that leverages both your baked AO textures and real-time ray-traced occlusion.

AO Connector stores your original material connections before making any changes. When you use "Remove AO," the addon completely removes all AO-related nodes and restores your original Base Color connections exactly as they were before. Your material returns to its pre-AO state without any manual cleanup required.
