Geometry Nodes - Extrude - how to keep original face?

[zeroskilz]

Here is an updated version of the node-group you desire:

… it pre-shrinks the faces, does the extrude, merges, and then puts the “shrink” back (if Individual Faces setting is on).

But yeah, don’t assume just because you have a hammer that every problem is a nail.

Check this as an example of how to make random books efficiently:

Most significantly, unlike the geometries’ Count or equivalent inputs, the Amount input for the Duplicate node is a field input. So, in previous versions doing the following would be non-trivial (whereas now it kinda is (if you’re familiar with GN)): [image] [image] … before you had to come up with non-intuitive strategies to produce enough points and then distribute them in some way, or you had to over-produce points and then delete a random amount. Also, just demonstrating points here… t…

Arrays of books! (Geometry nodes)

Hello ! I needed a little break from my procedural buildings , so after seeing an amazing talk by Anastasia Opara I tried to reproduce her book generator in blender (toward 26mn in the talk) : [image] [image] I didn’t think it would be that much complicated, but eventually I figured out a way of doing it… Mainly because there is no loop in geometry nodes yet, I find that it was hard to replicate exactly how she did it. So I find my own way in the end. For those interested here is a short …

Good luck!
