I've never heard of isolating the green channel of the normal map and using it as a paint layer. What effect does that create exactly?
WARNING They dont listen to their users as much as they like to say they do. Check their forums. Plenty of requests go unanswered. Their "To Do" list has been outdated. They lack staple features such as a Text Tool, Adjustment Layers, Channels, Layer Styling, Proper Cropping. Paintstorm cant even resize a photo correctly (It will always leave a border when resizes). You also run into square artifacts occasionally. There have also been several instances were paintstorm was detected as malware, once called out, the dev reuploads a clean version. This happened at least twice from forum reports and Virus Total. Aside from the very obvious lack of support and maintinence. The brush system is good. However a good brush engine will not replace the other basic features and functions paintstorm lacks. DO NOT expect support. This is definitely a homegrown app and it shows. If you want a versatile brush engine, clip studio or even krita is where its at.
How it works
It works by sending a weblink to your email, which when clicked, allows you to access and look around the rendered results. Think of it as Google® Streetview® for your own building designs. All it takes is a few minutes to set up and render.
It works on phones, tablets and desktop computers and nearly all browsers are supported. The best news is that you do not need to learn anything to get started. All you need is Lumion 5.7 and a few minutes later anyone can take a look at your designs.
Build your scene
You create a project on MyLumion.com by using the Lumion software package. Lumion allows you to import a model from a CAD package like Revit or Sketchup. After importing, you add trees, vegetation, materials, people, weather and anything else you need to express the intention of your designs. Showing your model in the context of life-like objects allows you to let people experience how your design will feel once it is built.
Once you are done enhancing your model, you click a button to enter MyLumion.com mode. In this mode you can define several viewpoints in your scene. Later the customer or colleague can switch between these points to view the model from different angles.
Render the 360 panorama
With all desired viewpoints in place, you hit the render button to send your Lumion project to MyLumion.com. After providing your email address, Lumion will quickly render many images and combine them into 360 panoramas.
Upload to the cloud
Once the panoramas are automatically uploaded, Lumion presents you with a button to view the result in your browser. An email containing a link to the result is also sent to your email address, so you can view your project at a later time. You can also forward the link to other people so they can look around in the scene that you rendered.
