*@Jonathan DelleCave* Thank you for pointing this out! This is a feature that is new in Blender 2.90. I did not realize this at the time of recording, but luckily Blender 2.90 is going to be released later today. I'm glad the course is helping you!

*@Huân Lê-Vương* Yes, I'm using a plane, but you can also use a cube and align the UVs accordingly

*@Huân Lê-Vương* There I simply went into edit mode. If you want to be able to see the wireframe in object mode you can also activate it as a viewport overlay.

*@Simon Thommes* thanks.

*@Kevin Tatar* I mostly figured things out on my own. A lot of this comes from math education and then trying to apply it to creating patterns. I like to figure things out myself but also when I started doing this sort of things with shader nodes the resources were really sparse. Now there is more, but as far as I know there still is no other comprehensive course for it. That's why I am making this series.

*@kroneborge* Awesome! That is totally valid. It is essentially the same method. I was doing it this way as well when we had very limited functionality on the vector math node.

I would recommend to still get used to the way of using vector math nodes though. Having a more compact node setup makes you node-tree much more readable and also flexible for quick changes.

*@victor p* As far as I can tell this might unfortunately be a restriction due to the complexity of the material. Can you tell me what graphics card you are using for rendering? And do you have the same issue when trying to render the resulting shader from this video that is linked in the description? I recorded the video using a GTX 1080.

*@Simon Thommes* the floorboard example you attach on the description works fine in my computer

i also using gtx 1080. Any idea why? Here is the blendfile if you have time to take a look at it

*@Simon Thommes* I found the problem, its in the uv map node, if i uncheck the "from instancer" then the brick pattern appear.

*@victor p* Ah, interesting. Good to hear you figured it out!

*@Simon Thommes* Thank you

*@Aron* Correct, the calculation of the pointiness is done before the displacement and thus it does not affect it unfortunately. For emphasizing edges in the shader you would have to create a map of the edges as another pass youself.

@tredeau It is not planned to add more workflow examples for this scene. If you take a closer look, you can see that the nodetree for the stone walls is very similar to the wooden floor boards, that I explain in this video. In fact the only thing that is really different is the rock texture itself. The main part of the shader is the tile pattern, that is the same as what I explain in here.

@L-L The 'never below 0' was a bit of a slip on my part. If the negative values are scaled up enough, adding 1 will obviously not make them positive. The main takeaway to focus on here though is not to necessarily make all values positive, but to center them around one after the multiplication. That way, multiplying with 0 will make this tilt operation have also 0 impact on the height map.

@Simon Thommes Few I'm actually releaved because I've looked for all the possible ways that adding 1 would prevent having negative values and it took me quite a while and I still couldn't figure it out it was driving me crazy ! I totally get how centering around 1 is useful afterward, thanks for taking the time to answer.
