Add Mesh: Neural Network Creator generates fully connected neural network structures inside Blender that can be visualized and customized with a click. It provides three creation methods: a 2D Neural Network quick mode for flat structures, a 3D Neural Network quick mode for volumetric ones, and a Geo Neural Network advanced mode built on Geometry Nodes.
In the quick modes, 2D networks support up to 30 layers with up to 10 neurons per layer, while 3D networks support up to 20 layers with up to 100 neurons per layer. Neurons can be spherical, cubic, or disc-shaped, and are created as instances, so editing one updates all. Synapses are separate objects for individual styling, layer spacing is adjustable through the Layer Distance Factor, and each network sits in its own collection.
The Geo Neural Network mode uses Geometry Nodes for a non-destructive workflow with editable parameters and no fixed limit on layers or neurons beyond your computer's performance. It supports any mesh object as a neuron shape, per-layer materials, and layer offset on the X and Y axes.
