The color codes is a work in progress feature, only the NEW nodes introduced in this version 1.8 have this capability. You can choose from a new option in the addon preferences if you're using a mostly dark, or mostly light Blender theme, to let SceneCity adapt the colors to your theme. In larger and more complex graphs, that kind of information becomes more and more important to debug errors.īecause color codes are used, they may or may not be suited to your Blender theme. The nodes that should have executed but couldn't because of a previous error will be in yellow. In case of error which one provoked it in bright red (with the usual error message in Blender's console), so you know exactly where you did wrong in your graph, usually because of a missing or invalid input.

Secondly, after execution, the nodes will also show you which ones have executed correctly in green. Execution would need to be triggered, and would waste your time and processing power in computations that would lead to an error anyway. That will make your life much easier to be able to spot immediately simple errors such as missing inputs, even before executing anything. The nodes now use their background color to show you useful information, and therefore speed up your workflow.įirst, which ones have missing inputs are colored in light red.

The execute node is NOT compatible with all the previous nodes, that will come progressively with each subsequent update. This is very useful while you're modeling, a road or building for example, and you want to quickly and easily execute SceneCity to check the result regularly in your 3D viewport. That way, you don't have to click on them or even see them, no matter what you're doing inside Blender. It will execute the execute nodes of your choice, that means all of them (across all graphs) that have their checkbox enabled: 'Execute when using key shortcut'. To work faster, you can also use the new key shortcut: CTRL + SHIFT + E. You can have one or many execute nodes in the same graph, and each one of them can execute one or several parts of your node graph, meaning you can execute, in a single action, completely different operations (big or small) in the order you want. When you press the button of the execute node, all the connected nodes will execute.

You now plug the nodes as you want, chaining procedural actions, then you plug the output of the last node of your generation process to an execute node.

That method of execution was cumbersome with larger node graphs, and was error-prone. You no longer have to execute the steps of your generation process on the nodes manually and individually, that means no more 'action' buttons displayed on the nodes. The way you execute your graphs is now more streamlined.
