This is interesting. If the image is generated successfully, it would be nice to have a sense of how the image was created in what workflow, more than using a WebUI.
@nop i generated this one later and seems like it came out good.
And yeah supposedly this way of generating images seems to provide more flexibility in the creation of a workflow and more understanding on how the image generation works. You could chain several nodes and provide a finished image within the same job.
I've used nodes a lot in blender so it's not a foreign concept to me but i think still would take some time to get used to it.
