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 Their "To Do" list has been outdated.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.
Have a look at a mighty Rock Generator for 3ds Max by Poly Design. The script brings tons of useful features, giving you all the tools to generate all kinds of rock shapes in no time.
- This script generates procedural random shaped rocks both low poly and high poly.
- Low poly mesh matches too close to high poly mesh so you can easily bake a normal map from high poly to low poly.
- The low poly mesh is automatically relaxed UVW mapped.
- Low poly mesh has clear non-overlapping UV’s.
- You can change advanced parameters or you can simply click “random seed” then click “generate detailed rock” it will give totally different results.
- If you want to create same rock more than once, you can use same seed number to generate rock.
- Use live parameters to quickly adjust shape and details.
- Live resize mode has been added.
- You can now create asteroid like rock shapes
- You can use manual edit tool to manipulate rock shape
- You can use intensity slider to negative values for interesting effects
