You’re missing something. POM or Parallax occlusion mapping, is a good option to replace displacement, it doesn’t increase the polygon count but it does provide depth. The only weakness it has is it can only go into the surface, not out of it. It’s better than normal mapping.

[@telefonkirtys]

Dunno about blender specifically, but parallax displacement doesn't need any specific maps. It's more of a Shader effect and if your software of choice support it. It should work with standard displacement maps.

[@gamerboygb6041]

​@telefonkirtys with enough effort, Blender can in fact support POM

[@unyu-cyberstorm64]

2:47 I'm not criticizing but wouldn't a rubber that absorbs all light appear black instead of white? I've been trying to understand what makes something reflective for a long time and I don't think it's just how smooth it is. You could polish any material to a 'mirror finish' of flatness and it wouldn't be as reflective as the metal used in mirrors. Why does a perfectly smooth, flat rubber surface scatter light so well? Is it that some of the light penetrates and bounces around before returning to the environment? I think this is the explanation but I'm not certain, I've always heard it explained as surface roughness being responsible but I'm not convinced.

[@renealbrechtsen9743]

Now I'd like to know how to make those maps. Particularly normal and roughness maps.

[@Dumka78]

My bad, You need to enable experimental feature set under cycles, and them add subdivision surfaces modifire with Adaptive subdivision enabled.

[@mattburkey]

This is a great overview, but you would do well to inform newbies that not all normal maps are created equal. There are two types OpenGL and Direct X normal maps, and the difference between the two is the GREEN channel is inverted. Therefore, if you load a normal map and the shadows on it looks 'not quite right' somehow, you're using the wrong kind of normal map. In the intance of Blender - which uses OpenGL normal maps - loading in a DirectX normal map will look off. How can you tell which map is which? Sadly, there's no simple way until you apply it to your model. Luckily, the fix is simple, drop an 'RGB Curve' node between the normap map texture and the normal map node, and simply invert the green channel. Alternatively, uses a 'Separate RGB' node, with the green channel connected to an invert node, and then all channels back into a 'Combine RGB' node. Unfortunately, these two standards have co-existed for years so, you just have to fix them as you see them. A good way to check is to add a green inversion solution as detailed above and switch to a rendered view (Eevee/Cycles) and simply press 'M' to mute/unmute the node and as you toggle back and forth you can see which version works better. Keep up the great work! (The same is true loading OpenGL textures into a DirectX based engine/renderer)

[@TechTotal94]

Thank you, I understood a bit, but I want to see it practically. Do you have any KZbin video that can explain it to me better?

I need help am new to blender and I was just trying out this...... And then I can't find the displacement node which I can apply the height map

[@GraffinityOfficial]

Maybe it is not visible because you are using eevee instead of cycles.

[@fury7992]

@@GraffinityOfficial I have another doubt... Can I use a displacement map instead of a bump map and vise versa

[@GraffinityOfficial]

@@fury7992 well height map can be used to displace the plane but it can also be substitution for normal map, if you use bump node. This is a friendly advice. If you think something can work, try it first and then ask if something is not clear. It will be faster for you to find out than waiting for my response. 💪

I'll never understand why normal mapa must be set to non-color if they have colors

[@GraffinityOfficial]

I think it is because blender is not actually using the color information, rather data stored as colors. My theory is that Each RGB channel is used as a greyscale texture which is then converted into XYZ coordinates.

[@phizc]

I think the default is to apply gamma correction to color images. That would mess up the normal maps since they're saved with a linear color space - I.e. the difference between 0 and 1 is the same as between 254 and 255. With colors after gamma correction, the intensity change between 0 and 1 is much less than between 254 and 255. I.e. without gamma correction, going from 1 to 2 is 100% increase, while going from 100 to 101 is a 1% increase. Gamma correction makes it possible to reproduce smaller intensity changes in dark areas.
