Wysilab has presented Instant Terra v1.4 which now allows users to create and share components.
Create components from nodes in the graph to reuse in your project or export them to other projects!
Open the component graph, click on any node, and see what’s going on inside in real time!
Create new component inputs and outputs, including terrain, mask, value, color map, and vector map.
Drive parameters within a component by linking value parameters to the node’s optimal connectors.
Create component libraries to use in your project.
Export your components as .terralib files and import them into your other projects.
Use the Global libraries to automatically share your components among all your projects.
