Connector Unity

Twitter Follow Community forum users website docs


This repo holds Speckle's Unity Connector package + a sample project (Speckle playground).

The package offers several Unity Components to send and receive data from Speckle, and allows developers to easily develop their own components and features. It has a simple UI, and is missing some of the comforts present in other connectors. The connector uses our Speckle .NET SDK.
