Bump maps are easy for the user to mess with, but more costly for the renderer as it has to lookup neighbouring pixels in the map and calculate the normal. In a normal map, the normal comes directly from the color and no additional computations are necessary. Normal maps can store a gradient with a single color that doesn't correspond to flat, whereas a bump map would require a gradient. Therefore bump maps may require higher resolution images and at higher bit depth to avoid banding effects to show up, especially at high zoom levels. Cubic interpolation can help, but it won't do magic. Using normal maps the normals are independent on density; a 5 degree tilt will be 5 degrees no matter how dense you repeat it, but the height perception will vary instead. It's opposite for a bump map; put those peaks and valleys denser together and keeping the height, the normals will vary. Use *ONLY* normal maps whenever depicting known angles are critical. Normal maps can be tricky as hell to manipulate (blend, rotate) if you want to do it correctly. Sure, simple overlay may work *good enough* if angles aren't critical, but it won't always work as intended if doing texture bombing, triplanar mapping, or you can't be bothered to setup proper UV space. Personally I usually work with bump maps instead of normal maps; the hit on offline rendering isn't that critical for me, I (usually) can deal or work around the downsides, and they're just far easier to manipulate whenever I want to eliminate seams or texture repeats. I also like to randomize the look of the assets I use multiple times in a scene, so baking out a normal map just doesn't work that well for me. Normal maps are technically the better option result wise, but often convenience just wins for me.

OK. So, if I understand correctly, normal maps essentially take the geometry that pokes out of a plane and flattens it into a hologram as part of the texture. In the same way that a hologram can be seen from a bunch of different angles and show different shading depending on the direction and intensity of the light source, it _cannot_ cast real shadows on anything around it that weren't captured as part of the holographic process that made the image. I guess another way to think of it would be like if the surface was made up of flat LCD panels (with absolutely perfect 180° viewing angles). You could make it so that those panels react to things like lighting and viewing angles with cameras and tracking and such to make the panels display a reasonably convincing illusion of depth that reacts to the viewer, but nothing can ever poke up past the surface of the screens used on each surface. This means that the different colors in a normal map are a bit like looking at an anaglyph 3D image (the old red and blue type of 3D) without the glasses. The more the color is distorted away from that flat, magenta/lavender-ish color, the more that the original protruding shape is being flattened down to a plane. By contrast, a height/ displacement/ bump map _can_ cast shadows, since it's essentially just a way of storing Z axis data in a flat image. Height and displacement maps are _basically_ the exact same thing, the only difference being how the engine renders the same data. A height/ bump map uses the same sort of "hologram" method that keeps the surface flat, while a displacement map _will_ actually poke out from the surface (and cause a bunch of geometry to be added) Please correct my horrible interpretation of these concepts.

Normal maps (and I think bump maps?) cast shadows that react to dynamic lights, but the actual polygons still looks flat from the sides. The displacement map doesn't create new geometry, it just modifies the existing geometry, but for best results you would want a fairly dense mesh.

Thank you!! This was a life saver!!! My textures were looking pretty weird after I used my normal map, which made me panic. Then, I remembered the extra nodes that go in between, but wasn't sure if I needed them. You helped me understand what exactly I needed, and I am quite happy with how my texture looks right now!!!

Great video! just a small clarification in 5:45. the Blue channel is actually used to normalize (make all of the vectors the same length) the vectors the Red and Green channels produce, it's just faster having it stored in the Blue channel than calculating that when rendering, but really, you have all the info you need in the R and G channels.
