I have recreated the node setup to generate a curvature map from a normal map, the result is closer to substance designer. Important note: the normal map must be imported in Linear mode (that means converted in sRGB):…
It's impossible to tell from just a picture, but make sure that the normalmap is fed through a Normal Map node, and that its Image node is set to Non-Color (as opposed to the default sRGB). You will have to first pack the image or save it to disk after baking in order for the option to be available from the Image Node. All…
@wilson66 This would be very easy to do using the Sverchok node based geometry addon. This can be used to generate a unique transform matrix with slight randomization to place each paving stone, not to mention a lot of options for randomizing the stones themselves. Creating the array could be done within sverchok using a…
Getting a simple sphere gradient in the node editor is a pain. I feel obligated to tweak all parameters using a color ramp all the time. And we all know that the color ramp node needs some serious care from a developer. :p ahah
