Model steps are used to show different models or areas of models in a workflow.
The shirt configurator product on our demo store uses the model step to change what kind of collar, cuffs and placket a shirt has.
You can use this step to customize any kind of model you like. You can also add new models to the scene when used with a condition step.
In this example we have a wine bottle, the customer can choose to add a wine box for extra cost. The model step is used to update the scene and show their updated selection.
You now set this up like any other step. Fill in your general information and add your desired glb's to the options.
