For those having trouble with missing transfer attribute node part at the end. 1. Add three nodes, Position Node', 'Index Node', and 'Sample Index Node' 2. Connect 'Position Node' and 'Index Node' to the 'Sample Index Node''s value and index 3. Connect the 'Distribute Points On Face Node' to the Sample Index Node's Geometry 4. Connect 'Sample Index Node's Value to the Set Position Node's Position.

Hi, thanks for the excellent explanation. as you mentioned Transfer Attribute node could be replaced with Sample Nearest Surface node. how can be the value connector from that node linked with position connector at the Set Position node. if I make connection directly then I get a warning display: "no group output attributes connected". many thanks in advance for answer.

@JoeyCarlino Жыл бұрын

You need to use the sample index node and in the index slot plug in a sample nearest node. Use the same geometry for both nodes, then you'll have an option to use points.

@gottagowork 2 жыл бұрын

Tutorial idea - since I need it 😁Some kind of curve controlled "slat wall" that will survive boolean cutouts for windows and so on. Each slat should have a random value for it that gets sent over to material nodes (this breaks down for me when I boolean both in geo nodes and as a modifier). Ideally the normal offset from world normals (rotation value would work too I guess) should also be sent over to material nodes. Material nodes can use image based box mapping for straight walls, but around curves you'd need a manual triplanar mapping system which orients itself on a per slat way; i.e. the straight part would have rotation 0 (aligned with x i.e.), rotation 90 for perpendicular wall section, and somewhere between 0-90 along the curve between those two section. Point is random lookup (using random value -> 1D white noise) of a wood texture where each "manual triplanar mapping" orients itself to match the orientation of the slat. I can do the slatwall just fine using geonodes in a destructive fashion, but I'm screwed if the project changes and I have to move walls around, as I have to apply it and separate by loose parts in order to use image based box mapping by rotating the parts origo to match the geometry's orientation. Although I prefer manual triplanar mapping/image box mapping myself, others may prefer UV data to be sent over to material nodes.

great vid! I know you've already explained the transfer attribute switch to sample nearest / sample index, but it seems like the new setup has an issue with the curve not wrapping fully around the object. I believe this is because it doesn't take into account that it shouldn't set spline position to the same point location more than once, but i cant seem to find a fix. any suggestions?

You can use a float curve to change the thickness of that's what you mean. Take the factor from a spline parameter node, plug it into a float curve and plug that into a set curve radius node.
