Excellent, learned so much from examples!

You guys are really good at this. If requests are still taken into consideration I would like know how to clone shapes? say I wanna have small circle followed by small rectangle in a grid?

    That is super helpful Hrovje much better than documentation which is totally dry and generic, thank you!

    ok then, is SSS shader possible?  Bevel shader? Ocean with foam shader? :)

    Not only that is poorly done, it is missing some nodes. Notice that triplanar node is not in the docu. This indicates that R20 was rushed although I haven't had single crash with nodes so far but dfid experience some glitches.  I would like to have some real world examples of triplanar, in range, compose/decompose matrix

    It's the manipulating UV's that most interests me,  I think,  with the Nodes.    I need to learn the features of GET CONTEXT,  which are eluding me at present...:wallhead:

    Okay,  I'll submit one!    It's the first good "trick" I've learned on my own using Nodes.

    The Triplanar Node is allowing you to assign 6 different colors to an object---   a simple Sphere---   based on the Sphere's 6 local axes orientations.     Four pure white Lights are shining on it.    If you can do this with colors,  imagine what you can do with bitmaps or generated procedurals...    Things can get real fancy,  real quick!    :wow:

    No big deal,  really,  but it's my first little "breakthrough" with Nodes.    :lol:   (The circular plane beneath is textured with an ordinary Material)

    Check the attached images to see the main difference. The object is a heavily sculpted plane with hige UV distortions, in the triplanar-off image you can see the stretching very obviously. In the triplanar-on image you can see that there is no stretching, though the transition frome one projection to the next is slightly visible. The main advantage is that it takes practically no effort. Check triplanar01 for an example where a simple tileable wall image produces something that works as a secondary item in a scene within seconds.

    I would say so, but I am afraid this exceeds my capabilities, at least SSS shader does, although fake SSS is possible with AO. As far as Bevel shader and ocean shader that would be doable, will try :)

    SSS is not in the books due to some technical limitations that we can hopefully overcome in the not to far future. Bevel shader has some legal aspects due to patents, the basic technology to implement it is there though. Ocean with foam is something realy complex and i honestly don't know if the node based materials in their current form are capable of it. An approximation is very doable though, but still a lot of work to create it in a usefull way.
