Texture with Slope Blur Greyscale
The Slope Blur node is one of the most useful and powerful nodes in Substance designer. It can be used in many different ways, but in our case it will mainly be used to create a damage effect on our cornices, our bas-relief and so on.
When you blur a noise with a blur node, it creates artifacts that once fed in a Slope Blur, will generate a very interesting erosion effect. The blur Intensity gives you the control on how chiselled the noise is. The Slope Blur Intensity gives you control of how far the effect is propagated.
Another trick to pinch a shape with this node is to plug in the Slope Input the invert of what you plug in the greyscale Input. Rather, if you plug the same shape in the two inputs you’ll get an inflate effect, as you would in Zbrush.
The program is a real toolbox, so don’t hesitate to explore different sequences to create your own recipe.
