This video will show how you can use COPS (Composite Operators) to generate normal maps inside Houdini. The convenient thing about COPS is that it is lightweight and easily editable, which means that you can iterate and make many different versions using a combination of COPS and SOPS (Surface Operators... eg. geometry) to get the image you want to make. You are essentially layering all the elements together, as you would in any 2D image editor - but inside of a 3D application :)

    I've always wondered how to get those pluses on the nodegraph and how to get the straight line node connections?

    Thank for you this excellent tutorial. Is there any end to Houdini's magic?

    @MrBrN179 you hit D for options over Network Editor Pane and select "Points" for Grid Display. You may want to enable "Snap to Grid" and then change Grid Spacing. I changed mine to 0.5 x 0.5 and as for straight line, choose in Display tab > Link Style > Rounded.

    @ Daryl :) thanks for the kind words. As for the magic.. who knows what we can pull out from the hat :)
