[@RC_Russell_Designs]

But, for a beginner, way to fast. Great info thou.

[@SoapyTarantula]

I really liked how you quickly explained the pros and cons of each method. A lot of tutorial or tip videos don't really go into *why* something shouldn't be used all the time, so its a surprise to see someone that does. Well done!

[@DamianMathew]

SoapyTarantula ah that’s a good tip! I didn’t even actively think about this, just automatically mentioned it. I’ll try to always mention reasons in the future. I’m glad you liked it and thanks for your comment!

[@ABaumstumpf]

While height, displacement and bump-maps are all very similar they are NOT the same. Heightmap specifically refers to the height of maps - duh - and as such is a simple 2D greyscale image. It is not even about shading or displacing but generating the actual geometry. It is very often used in games as it is a very simple yet good-enough method. (In general the landscape is represented solely by the height-map with no other data needed for the geometry, for the rendering the index in the map is directly used for x/y coordinates and the value of the map is used as the height). Bump-mapping specifically refers to shading Only. Those maps are also just greyscale but contrary to heightmaps they are used on objects to change how they interact with light. In general this is done in the simplest for taking the gradient to the surrounding pixels as the slope of the pixel and using that to compute the brightness. Normal-mapping commonly uses 3 channels (albite 2 channels is enough) and directly stores the normals at each pixel - so more accurate than good old bumpmapping. And displacement-mapping is kinda like an application of height-mapping on 3D objects - allowing the actual geometry to be altered. This can use a variety of textures and interpretation of those - the simplest is using a simple 1channel greyscale to only get the amount it should be displaced along its normal. The more powerful version is 3 channels - height + 2 normals - as that gives more control over how edges in the texture look like (You can make them hard edges or smooth curves). This of course needs actual geometry. And it also comes as a 3D displacement where the 3 channels represent a displacement along all 3 cardinal directions, making overhanging geometry and the likes possible - the most powerful variation. As you are dealing with actual geometry here this of course is in general far more powerful but also resource-intensive of the methods so far. If you just want the nice highlights on a coin it makes no sense to have a very high poly-count and displacement-mapping when normal-mapping will basically give the same visual result. But if for example you have the outside of an old stone+wood building with rough edges then displacement really brings it to shine. And as having all the geometry in very high detail is usually a waste of resources it is mostly used together with view-dependant tesselation: an object far away and small does not really benefit from tiny displacements, better to just tesselate the nearby objects to give them extra geometry for better visuals. There is also parallax mapping: bump/normal-mapping have the problem that they only affect the surface-normals, parallax-mapping also tries to compensate the texture-coordinates based on the viewing angle. If you look at actual bump/normal-mapped geometry while changing the viewing-angle you notice that only the lighting changes, the texture stays static - while with parallax-mapping you see a stronger 3D effect as it looks like the surface is experiencing parallax. But this too does break down on shallow angles as it is a simple 1 step lookup-offset (You check the texture-coordinate for its value, then use that value alongside the viewing-angle to look up a new texture-value that is far closer to what you would see if the surface was actual 3D). This takes slightly more performance than normal-mapping (which is identical to bumpmapping in performance) but gives way better results. And finally there is parallax occlusion mapping: It tries to solve the inaccuracy of parallax-mapping by using an iterative process that allows for the texture to hide (occlude) it self without causing big artefacts. It is again more costly due to being an iterative multistep process (often in the range of 5-10 lookups) and breaks down at sharp corners, but on smoother bodies it gives a near identical visual result to displacement-mapping while requiring far less geometry and still usually being quit a bit faster. The terms sadly often get mixed together, specially parallax mapping in recent years go highjacked by 2D game tinkerers with no idea what they are talking about (no, not even just confusing it with parallax scrolling but just outright making up shit).

[@DamianMathew]

ABaumstumpf great explanation! And interesting you mentioned parallax, in Blender this has not made it’s way yet (as far as I know at-least). l get your point, maybe I wasn’t clear enough in my video. What I tried to say is, that there isn’t really a difference in the map itself (bump, displace and height). The map will be black and white, unlike a normal map and can be used for bump, displace and height. I get that they are different, but what I tried to say (mainly for beginners) is that there isn’t a difference and you can use all 3 for the same thing. I mentioned this because beginners are also often confused about albedo, diffuse and base color. I get that these are also not the same, but for beginners it is easier to understand if I just say they are “the same” you know? Often when I explain things like this I try to make it understandable in a way I guess, so people are not confused with all the detail. They can learn the details after.

[@ABaumstumpf]

@@DamianMathew Yeah, bump, displacement and parallax maps can als use the same texture, just different maths and visual results - i did enjoy your video anyways.

[@DamianMathew]

ABaumstumpf yeah exactly. I will try to be more clear in the future, I still need some practice in using the right words for making clear on what is a fact and what I just mean in general. I am glad you liked it!

[@DamianMathew]

Glad it was helpful!

[@JayJapanB]

You can also make complex meshes by applying in the displacement modifier then decimating the mesh. Can be useful if you want to break a shape or silhouette up without massive polycounts.

[@DamianMathew]

[@francofx]

I think last method is best with 2k or 4k textures, and use it on some key elements of our render. So using a mix of 1st and last method would be fine... (for concept enviroments)

[@Anakianaj]

Sometimes YT recommendations *do* work. - Just got into Blender and was wondering about the difference between the maps in terms of names and function. And here you explaining just that in a way that I don't really have any questions left - Thanks! 😊

Thanks a bunch. The explanation about gpu ram at the end was super interesting. I haven't found anyone talk about.. what makes a good blender computer.. or something. Also, idk if I should render with my gpu or cpu. CPU is better but I did just have to replace my 3800x after 6 months of use so... just thought about that. Hmm, bad batch? /shrug lol

[@arkhamrejectscommunitybatr6599]

If I wanted a 3D print a wall showing the texture. Would a differential map be the best way to go about that? Also I don’t care about the color or shading is there a way to turn that off to hopefully allow my computer to not die during this process. I literally just care about the texture

is there a way to displace the image and bake it into the image and then use a low poly model to get the same visual without actually having to render the displacement in the final render? Using it in an animation sequence as well.

POM is amazing but hard to implement from scratch when a beginner. I'd like to learn how to directly paint height maps on the model using POM as a preview.

[@NexVice]

So what's worst? More Triangles or BUMP Map?

[@DamianMathew]

Depends on the case to be honest. Generally you could say that more triangles are usually bad. Because renders longer and melts your PC. And when sending it’s high mega byte as well.

You are completely right. The correct way is always to use non-color data. On my examples I think it won't make a visual difference, but on Normal Maps it definitely will.
