Aqueduct

Aqueduct is a node based procedural material engine for creating, editing and sharing material graphs in the browser. Materials are built from composable GPU shader nodes, drawn from a built in node library or extended with custom nodes, and every graph stays transparent and editable rather than being baked into a black box. It is built for technical artists, game developers and studios that author materials for real time engines. An Unreal Engine plugin syncs channel packed material .uasset files and texture maps to Unreal with one toggle, so edits to a graph show up in the engine in real time. A native MCP server lets agents such as Claude Code and Codex edit graphs, render them and create new shader based custom nodes with adjustable parameters. Graphs can be shared as links that open as fully editable, live rendered snapshots, exports run up to 4K, and a CLI supports pipeline automation or a locally hosted MCP. Pricing is published in two tiers. The Community License is $0 for individuals or companies below $200k in annual revenue or total funding, and includes the editor, unlimited projects, custom nodes, MCP access, the CLI, the Unreal plugin and commercial use with no attribution, plus 5 Cloud MCP render minutes and 1 GB of bitmap storage per month. The Studio License is $49 per seat per month for organizations at or above that threshold, and adds a team workspace, priority technical support, 250 render minutes and 50 GB of storage. Additional hosted usage is billed separately. There is no perpetual license yet; the vendor says one will follow a local desktop version of the editor.
